View Full Version : Single seat woods buggy

09-12-2014, 12:12 AM
Well I started a buggy build for my 6 year old boy. He and I started bending and
Welding today, got more done than I expected.
Overall length 76 inches
Track width 45-50 inches
A arm front suspension with 7 degrees rake and 5 degrees castor
Not sure yet about rear I want to use a small lsd either on a straight axle
Or machine some drive flanges and use some small Empi cv's, probably 16.25
I'm pretty sure the can get 25* of range.
Looking to use either a preditor clone motor with a comet torque converter or
I can get a new 150 cc automatic 4 speed with reverse for about the same price (Chinese motor).
10 inch wheels on 22 inch tires
I'm thinking about using Monroe sensa trac coil overs for the shocks
The buggy should finish around 300 pounds so it will be light enough for
The shocks. I believe the sensa trac springs are 60# rating.
Should be able to get 8-10 inches of travel.
Frame weight is just under 100 pounds
Main frame is .083 x 1/2 tube and bracing will be 1 1/4 .083
I know it is overkill but that is what I had in the garage.

Here are some pics from today, still probably need two to three more
Days to complete the main frame.

Great to see you get to build with your son. Now get some action shots of him holding up his end. Maybe throw a dictionary down to sit on and do the Vroom! Vroom!

09-12-2014, 03:27 AM
looks like a good start and building with the kids is going to be the best part:)

09-12-2014, 02:20 PM
Very cool project, I'll have a couple of those in my future for sure!!!!

09-17-2014, 11:33 PM
Was able to get alittle more of the frame completed this week.
We are hoping to start on the A arms by next week.

My kids are already way to excited.
The wife not so much...

Here are a couple pics of the progress

Now that's what I'm talkin' about!

09-18-2014, 01:20 AM
you cant see it through the helmet but we all know there is a huge smile on his face :)

09-18-2014, 11:55 AM
LOL that's agreat pict :D

09-19-2014, 04:31 AM
Vroom Vroom for sure. I love the small builds, everything is so much more stout with the smaller dimensions. I think the look might be saying, "uh dad, how about a steering wheel so i can pretend steer too?" :D

09-19-2014, 08:43 AM
That's the same gear I wear.

09-19-2014, 01:11 PM
My Jammy pants have Tellitubbys on them.

08-25-2015, 10:48 PM
Well after nearly a year my kids have decided they want a two seater.
So I'm gonna change the frame and fab up a two seater.
What I have done so far:
Obtained 13 Hp predator motor
40 series torque converter
Comet reverse gear box
I' will be using the s10 cv's and hubs.
I re drilled the hubs to match the wheels I have 4 on 110mm
I have made some flanges to match the bolt pattern on inboard side of the cv's
I'm hoping to have the track width of around 55" or so.
Not sure whether to go with semi trailing a arms, a-arms, or a three link.
I'm considering giving the3 link a shot

08-25-2015, 11:12 PM
Here is a couple preliminary frame design pics

Looks like my dog threw me a bone

08-25-2015, 11:26 PM
That is a cool project. Heck, you could probably sale the one seater frame, if you aren't using it.

08-26-2015, 06:04 AM
Was wondering what happened with your original thread. Glad your back at it! Looking forward to what you come up with next.

How did you end up making the spool? Are you using a splined shaft or a Keyway?

08-26-2015, 07:28 AM
I'm thinking because of the moderately low HP a 1" keyed shaft would work, but I am open to suggestions. I am planning on turning down the back side of the cv shaft adapters to accept some brake rotors.
Cv adapters are 6061 t-6 aluminum.

08-26-2015, 07:30 AM
My other idea was to fab up to rotor hats for the wheel hubs themselves

08-27-2015, 09:32 PM
Well it looks like I have the track width set around 52 to 54 inches wich should be pretty good for trail riding. Does anyone know the max angle for the s10 cv's?

http://i1290.photobucket.com/albums/b538/jleatham5/woods%20buggy%20build/kids%202%20seater/5805DDE8-5873-4B9A-9B9E-1596FD7720D8_zpsaqzhxyim.jpg (http://s1290.photobucket.com/user/jleatham5/media/woods%20buggy%20build/kids%202%20seater/5805DDE8-5873-4B9A-9B9E-1596FD7720D8_zpsaqzhxyim.jpg.html)

11-24-2015, 04:54 AM
Not sure on the max angle. Any progress to report?

11-26-2015, 04:44 PM
With that small of setup, you'd probably be good with just a single brake rotor and street bike motorcycle caliper at the spool.

What did you use for the inner cv adapters?

You should have enough on your setup there to check S-10 CV angles. Just droop it and rotate the wheel until you feel 1 or the other cv begin to bind. That's full degree.

You may be able to get a bit more width out of the spool to get a bit wider track for better stability. I'd push for marketing the track just wide enough to fit in the back of a full size truck bed. Then no worry of having to haul a trailer and still have a good size width.

Then again, wider the spool thicker it needs to be.

Did this ever get finished?

Does anyone know where he got those S10 flanges? They look beefy!

12-29-2015, 07:59 AM
I have made almost no progress since last post... I spend a lot of time working away from home..
But to answer the question I made the flanges. My son and I have a goal to get this thing done by end of June for a family reunion.

01-10-2016, 07:46 PM
Made some progress this weekend. We got the trailing arms figured out and was able to cut the plates and drill the bolt holes for the s-10 hub mount. I'm gonna make up a jig this week to fab up the trailing arms.
I'm planning on running the arms at 8 degrees and they should be about 28" long. I believe the overall track width should finish out between 58-60.

01-10-2016, 10:46 PM
You should make up some of those s10 flanges...I know some people who would like some!

01-11-2016, 04:32 AM
Which ones, inboard or outboard

01-11-2016, 03:44 PM
Which ones, inboard or outboard

I would think either...how are they mounted to your carrier?

01-11-2016, 04:16 PM
I cut a key way into them and drill and tap the 1" shaft for a retaining bolt.
But what I was asking is if you wanted a flange for the trailing arms of the carrier

01-12-2016, 03:46 PM

01-13-2016, 07:04 PM
Made the trailing arm jig tonight and cut and machined the bushing tubes. I should be getting a chunk of derlin tomorrow for the bushings. I have never made them before but I plan on turning them down to fit inside the 1 1/2 .120 wall bushing tubes with a .25" shoulder.

I made the trailing arm jig adjustable for length width and angle

01-17-2016, 02:05 PM
Made a little progress this weekend not as much as I wanted to because I only had today to do some work
Made 1 semi trailing arm, got some pics here.

I made the jig out of 1 1/4 tube and used 1 1/2 120 wall tube for the bushing sleeves which slide over the 1 1/4 real nice and holds everything straight. Arm has a 8 degree angle on it and measures 20 inches from outside of sleeve to outside of sleeve and has a 28" from center of bushing to center of hub. Got everything bent and cut to make the next one shouldn't take as long..
This stuff always takes way longer than you think..

01-17-2016, 02:09 PM
Oh ya forgot to mention arm is 1" .120 wall. Still have a couple pieces of bracing to add as well as the shock mount. I made and used a arms on my last build, so any constructive criticism would be helpful.

01-17-2016, 02:15 PM
One more thing in case anybody was wondering I'm using a s10 hub mounted on a 10" rim with a 5 inch backspace. Tire is 22x10x10. Wheel bolt pattern is 4 on 110

01-17-2016, 10:05 PM
Arm looks good...nice looking work.

I am impatient with mine...I can barely leave a piece cool down before unclamping it let alone make a jig![smilie=ecstatic.gi:

01-18-2016, 04:12 AM
I'm the same way, but I have finally learned to slow down a little due to the cost of making everything multiple times... Well let's be honest it's a lot more than multiple times. I have a MTN of scrap A-arms and frame parts sitting in my garage.�� Lots of trial and error, mostly error Lol..

01-19-2016, 05:33 PM
I think the arms look great. I was thinking you might need some more bracing, but you mentioned still having to put some pieces of bracing on.

just realized you are not that far from me. I'm over in Birmingham. one more to add to the list of southern folks on here. good stuff. :D

01-21-2016, 07:54 AM
One more thing in case anybody was wondering I'm using a s10 hub mounted on a 10" rim with a 5 inch backspace. Tire is 22x10x10. Wheel bolt pattern is 4 on 110

Can you tell me the diameter of the hub? I am using a 9" rim but I assume that really won't make a difference...pattern is 4x115.

01-22-2016, 04:58 PM
The trailing arm plate that mounts to the hub is 8" in diameter the hub itself is I think around 6", I will check for sure tomorrow morning

01-23-2016, 07:45 AM
S-10 wheel hub measures 5-11/16" in diameter

01-23-2016, 04:55 PM
Made a little progress today... Was able to get the other trailing arm tacked up
Layed out the two arms and wheels. The pic shows wheels 60" outside of tire to outside of tire.
If any has had any luck with making these s10 cv axles a little longer I could use some insight. Considering cutting and using a sleeve to give alittlymore length. I'm still not sure at this point.

Also considering mounting the motor above the comet FNR box and running a jack shaft set up directly under the motor and then to the rear carrier. Then I can get two gear reductions. I would like to be between 8/1 - 10/1

01-24-2016, 05:24 AM
Thanks for the measurement.

How wide do you want to go? I would like to stay within the 60".

Maybe some simple wheel spacers will get you the width you need?

01-24-2016, 04:11 PM
Since I am using the same engine and Comet reversing box, I am curious what your center to center distance is on your Torque convertor with the belt in the photos?
I have yet to receive the Gear box and TC parts.
I went with a 11.5" C-C belt and hoping the gear box is closer to the engine.
I like the results of your "mostly error" trailing arms

That's the same belt I am using, but I'm going to mount the gear box under and in front of the motor, I think it may be easier to get the sprockets centered on the frame. It will eliminate the need to extend the gearbox shaft and I can use a jack shaft for additional reduction

Here's a few more pics,

You can see why I would like to lengthen the cv's a little. Tires are still 60" out to out

How much wheel travel can you get out of those S-10 CV's?

01-25-2016, 04:04 AM
I haven't done a full mock up yet.
Button playing around with the CVs it appears you can get between 10 and 13 inches May be a little more if I lengthen the shafts

herman pahls
01-27-2016, 04:17 PM
13 inches wheel travel would be impressive considering how short those axles are.
How many degrees angle will those CV's take ?
I sure they will take more angle the less power you drive thru them.

02-03-2016, 06:32 PM
Well I got rained out today so I was able to get some work done on the frame

Here are some pics

02-03-2016, 08:53 PM
Looking good!

Do you have shocks picked out already?

I have a set of Predator 500 shocks fir the front and Outlaw 525IRS shocks for the rear...they are like 18 and 19" respectively.

02-04-2016, 03:29 AM
No shocks yet, I'm still trying to decide what to go with. I'm thinking about FOA shocks or possibly finding some used RZR shocks. Another idea is to use Monroe load adjusting auto shocks which are nitrogen filled and have I believe a 60lb Spring on them. Looks like they can get about 11 inches of travel. Around 26" extended and 15" collapsed. I could alway change out the springs if need be.

02-04-2016, 06:00 AM
Progress looks great. I almost forgot how small this thing is... had to go back and read the earlier posts.

02-04-2016, 01:16 PM
I'm shooting for just under a 60 inch track width and an overall length of just around 8 feet i'm thinking the wheelbase is going to finish out somewhere around 6 foot six. And if all goes well the weight should be right at 400lbs

02-04-2016, 02:14 PM
What's your plan for rear brakes?

I thought I had the rotors from when I swapped my Harley wheels but I must have given them away...figures!

02-04-2016, 02:21 PM
Not a hundred percent sure but I was going to possibly mount a rotor to the back side of the cv flanges on the center spool, maybe mount the caliper to the frame. Front brakes will mount directly to the hubs

02-04-2016, 02:32 PM
My sprocket will ride almost directly in the center of the buggy so I can mount my rotor pretty close to center too...thinking same plan on caliper mounting. I have a Vulcan front caliper.

I built the spindles according to the Shredder plans, but used the Raptor snout and trimmed the aluminum piece of the caliper mount...pretty quick and easy.

Got a few more pieces cut and welded on the frame today.. Not as much as I hoped but better than nothing

Looks like I need a couple more days and I should have the main frame complete.

I hope to be starting the front spindles and a arms soon.
I'm gonna try to locate the comet reverse gearbox on the frame this week.

Then I will start cutting and killing the flanges for the drive line.

Oh yea I ordered two of those poly seats from summit today

02-07-2016, 10:05 PM
Looking awesome. Are you going to brace the trailing arms?

02-07-2016, 10:40 PM
Excellent...your kids should be excited as heck!

I think I am building mine backwards. I built the front end, now I'm working on the trailing arms and mounts.

Next I thought may be the seat mounting and then get to the motor, gearbox and rear carrier.

The last thing I was going to do is the cage.

This seems like the way to go for my build since I really have no experience building these.

I was originally thinking 1.25" carrier shaft but now I am thinking possibly 1.5.

I picked up a rear disc with hub from a Cannondale 440 and it may fit a 1.5 shaft...then I could weld it on.

Also, after getting these S10 axles and hubs and building the Shredder trailing arms with 25" tires there is a lot of weight to move.

02-14-2016, 02:09 PM
Made a little progress today

02-14-2016, 02:42 PM

Are the trailing arms done? I would add another tube going to the bearing plate? Take a look at some other trailing arms.

02-14-2016, 03:02 PM
Looks like he has plenty of headroom!

How big is this kid sized buggy?

I want to do a build thread on mine but since I am obviously not putting the time and money into it that most guys do, it looks like crap! [smilie=sad.gif]

02-14-2016, 04:57 PM
Ya the trailing arms are still needing to be completed I wanted to get the main part of the frame done and get the wheels on so I can decide where to put the shock mounts.. I will definitely be adding additional bracing and tubes to the bearing plate, similar to this.http://i1290.photobucket.com/albums/b538/jleatham5/woods%20buggy%20build/9DE66A55-B28C-4AD6-BA97-38E68CE4D0F0_zpsz5zzx7q2.jpg (http://s1290.photobucket.com/user/jleatham5/media/woods%20buggy%20build/9DE66A55-B28C-4AD6-BA97-38E68CE4D0F0_zpsz5zzx7q2.jpg.html) This was one I made, but after I made it I realized the distance between the top and bottom tube was not large enough for the cv axle to fit through.

The buggy size should be big enough for my kids to enjoy for many years. I also made the rear engine area a little bit bigger in case I would ever want to put in a bigger motor.. The overall frame length is just over 8 feet. I wish I had gone a few inches wider though as the seats from summit are a hair to wide.. I may have to make a single bench seat instead of the two separate seats.

02-14-2016, 09:53 PM
I had thought about those seats for our other buggy...a Mano Deuce and they would not fit.

Look into RZR seats...I think they are narrower and you can pick them up on Ebay at a decent price.

08-01-2016, 01:18 PM

08-07-2016, 03:51 AM
Front end is looking really good, I've been following your build. Are your inner a arm mount locations going to stay single shear? Or are you adding another tab to the frame? It would be quite a fair bit stronger if your inner mounts are double shear. Just my thoughts, still Looking great.

08-07-2016, 12:22 PM
Ya i will be adding another tab to the mounts. I just have everything tacked right now in case i have to make any changes to the locations. The a arms still need to be fully welded as well and the shock mounts have yet to be added.

08-07-2016, 06:00 PM
Perfect. Coming along nicely.

Progress is looking good iron. what thickness are those a-arm mounts?

08-10-2016, 12:43 AM
A arm mounts are Cold roll 10 gauge. Im gonna gusset them up a little as well as the suspension mounts which are 1/4 inch.

08-15-2016, 11:36 PM
Started building another front spindle tonite. I got tje majority of tje pieces cut out and put in a little jig i made to keep everything symetrical. I should be able to get it welded up and on the buggy by the weekend.

Made a little progress today. Got the other front spindle complete less the steering and brake flanges
As you can tell kids are back to football and sports so the buggy gets 2nd when it comes to priorities.... More like last.
Anyway heres a couple pics

Those kids need to get their priorities straight! LOL

When they are 50 years old they will wish they didn't play football and they will still be having fun off roading!

Nice looking work as usual.

09-03-2016, 10:24 PM
Thanks for the kind words
Ya these kids have no idea the amount of man hours that go into these projects. It would be nice to have a shop where im not stepping all over myself everytime i turn around. I have more crap shoved into my garage than i care to tell.. I have to unpack it everytime i do some work. More time getting set up and tearing down than actually working��

Finished turning the other front hub today and
finally got it on four wheels.

Thanks MascMan,
was able to make alittle heady on the steering tonite. Got the steering rack mounted and finished the tierods. I had some 1" round bar I machined the clevis from. Not sure if they will hold up. I probably should have used 1 1/4 but all I had was 1". There isnt a whole lotta meat left where the bolt goes through. Couple pics.

Hello Iron
I could not figure out how to get the photo and text on the same post let alone 2 photos.
I am following your thread since you are using the same engine and FNR box that I did for my 9 year old grand daughters build.
I have had it driveable for several months and have had a blast driving it even though I barely fit in it by changing out to a Kirkey seat.
Just to let you know I started out with 5-1 reduction and kept gearing down till I got to 7.5-1 reduction to get what I thought was the best combination of acceleration and speed.
This was measured by the "seat of the pants" method.
What you see weighs 420 pounds and not all the cross bracing has been installed.
How long are you CV axles from flange to flange where they would bolt on to the center spool and then the outer stub axle and what kind of angle will the CV's tolerate at 13 HP power?
I have not been pleased the the acceleration jacking that takes place with the suspension design I went with.
I am very pleased with how much wheel travel I am getting and how well it handles the rough and small jumps.
I am considering your rear suspension design for the next build.
I ended up going with a drive belt that was for 9-3/16" crankshaft to comet FNR.
I also went with a $30 Vegas carb to get way better cold and hot starts.
The E start and reverse are a big plus.
I am looking forward to your kids first drive.

09-14-2016, 09:55 AM
Herman you have a real nice build there. Your buggy looks very similiar to mine.
What kind of top speed are you getting? And what size are your rear tires? I ask because I am gonna be running a 25" rear and I was thinking about a reduction of between 8:1. My buggy is a small two seater, it should probably just be a 1 seater but im stuffing two small seats in it. After reading your posts about the comet fnr gearbox and trying to come up with a jack shaft system to get the right reduction without using huge sprockets, i've decided I'm going to try to build a high low range with reverse gearbox, and take a chain completely out of the equation.

Now to answer your question about the CV axle set up in the measurements I don't have them exact just yet. The track with on the rear the buggy is it 59 inches and the CV axles seem to be short I may have to cut them and extend them. Im pretty sure I can get at least 12" of travel and maybe a bit more, but I do have concerns as the a axles themselve seem to be extremely heavy and in combination with the hubs I am starting to question if the 13 hp motor will have enough power. I will do a mock up of the rear end and axles this weekend and post some pics.

I copied some of your chassis lines from the small single seater build you started this thread with.
I am using 20" rear diameter tires.
I am guessing top speed to be around 30, I have removed the governor, fast enough for a 9 year old for now.
I should set up a bicycle speedometer to get a better idea.

Regarding gearing:
I read somewhere that determining the top speed when using CVT's is a guessing game and you either need to copy what works for some one else or experiment.
I have spent a lot on sprockets experimenting.
The specs for Comet CVT I am using with the 44D driven say 2.83:1 in low and 1:24 : 1 in high.
That calculates out to 35mph with 20" tires, 3600 rpm and 5:1 chain reduction which I thought would be a good starting point.
That combination turned out to be very sluggish acceleration and the engine did not seem to be revving out like it should.
So I purchased a Trail Tech tach/hour meter so I would know what the engine was doing.
This tach does not seem to give consistent rpm readings so that was a disappointment.
So I have geared down several times to get to the 7.5-1 reduction I am at now.
If my calculations are correct, if you use the same driven I am (44D) using and 25" tires and 8-1 reduction, at 3600 rpm you should see 27 mph.
If you use the 40D (which in hindsight I wish I was using) the top speed should be 34 mph.

Tell me more about your ideas with a HI-Low-Rev gear box and removing chains from the equation.
Chains and making tensioners are expensive and time consuming.
Like a Polaris Quad gearbox?

Please keep me posted on your "chainless "gear box idea and your CV axles.
You will get a lot of enjoyment watching your kids drive this buggy.


09-18-2016, 12:51 AM
Well here are some pics of the cv axle angles and some dimensions.
The max angle I could achieve was right at 25 degrees up and down and the wheel still spins freely.
The measurement from the back side of the wheel hub mounting point to the face of the inboard flange is right at 15.5" and it varied less than an 1/8" from full bump to full droop, so it seems there is very little plunge.
The total wheel travel was 11.5 inches, however if I extend the axles I should get right at 13" +or - alittle

09-18-2016, 01:01 AM
Since I am using the same axles and have the same 15.5" as you, do you think you can get 11" of wheel travel?

I know that my shocks aren't allowing me to get that but I'm using quad shocks.

What shocks are you using?

09-18-2016, 01:26 AM
Yes you should be able to the same wheel travel as long as your shocks dont limit the travel.
what I am using for shocks are monroe sensa track coil over, I then added a after market coil over kit so I could put some preload on them.

i appreciate the photos and measurements of the S-10 axles.
I am compiling info on what my next builds rear suspension will look like.
The nature of trailing arm suspension is that you need CV's that are able to plunge or the axle plunges in the CV inner race spline.
I am quite sure that you are getting more than 1/8" plunge from axle level to 25 degrees up or down.
Trailing arm suspension has very little track width changes when the suspension cycles where as rear double a-arm suspension has significant track width changes and very little axle plunge.

What do the S-10 CV axles and outer uni bearings sell for?
Do you need to have cores or pay a core charge?
S-10 axles would be over kill for a 13 hp Predator but they may be the simplest least expensive solution to get good travel/cost.
Keep posting till its done and then there will no longer be any grass in your yard.

09-24-2016, 01:45 PM
1986 chevy s10 (front) cv's and unit hubs ($135.00 ebay) At least thats what they were a couple years ago. Im sure you can still get them for that price. An added bonus, if you need a replacement they are readily available at any auto parts store.

09-27-2016, 09:12 AM
Hey Lugs, How much wheel travel are you getting on your setup?

10-07-2016, 08:39 PM
Great build, can I ask your profession, Ill assume machinist?

10-11-2016, 09:53 PM
Nope... I wish. I bought an Old matel lathe a few years ago and have been teaching myself how to use it. Everything else I do by hand. Way to time consuming. I did also make a air/hydraulic tube bender that works really well. But to answer your question I have been a carpenter for over 25 years, and since the day I started tinkering with metal and motors its all I do when time allows. I do have a desire to build either a cnc plasma or cnc router/mill maybe I can combine the two. I take the machinist comment as a compliment, so thanks

01-11-2017, 10:24 PM
Well it's been awhile since I've posted anything
It's funny how making a living can consume all your time. Anyway here are a few pics with some cardboard body panels, I think I'm gonna try to fab them up out of fiberglass.

01-11-2017, 10:42 PM
To make new trailing arms or not.
I picked up a FNR gearbox with axles and hubs but the hubs will have to mount to the arms differently. So should I just use the existing arms and rework them to accept the hubs or should I start over with new arms or possibly a 3 link instead? Also this new setup has increased my track width to about 63 inches.
Any help or ideas would be welcomed
Here areally a few pics of the new setup

Just a side note this gearbox has a 3:1 reduction and I'm told it's rated to about 600cc.

01-11-2017, 11:59 PM
Five link!

Go look at Kfabs thread or my briggs thread. Look at the pics of the carrier and rear links I just took. Looks like it would be pretty easy to adapt to your setup.

Move your shocks to the outside of the frame.


01-12-2017, 12:26 AM
That is looking good!

You should build that rear end to handle the bigger motor that you will be installing in the future when your son gets a little older...

01-12-2017, 09:54 AM
Looks very well built, what FNR box is that? I see the case is a casting, so it must be mass produced in some way.

01-12-2017, 06:37 PM
BULL I checked out that 5 link it's a nice setup, what about something more like an rzr with a single point of attachment to the frame for the main part of the arm and then two links from the back of the hub to the frame? Or is a test link that much better. Also is there a formula for calculating the angle where the two rear links connect to the frame? Does point where the inner cv rotate line up with the upper and lower mounting points for the two rear links. Should the mounting points on the frame be the same distance as they are on the hub?
Does any of this make sense?
Thanks for your help

JERM I'm not sure where this stuff comes from or for what make and model of utv it was designed for. A buddy of mine picked it up for me. I opened up the gearbox and everything seems to be operational, from what I can tell it's never been used. I have seen very similar gearboxes that come from China. I wouldn't be surprised if thats where this one is from. Hopefully it holds up for a few years but with these kind of things you never know. I had originally planned on using the comet fnr box but this seemed to be a little more stout and it has some reduction already built into it. Plus it eliminates the need for a rear spool setup. I can tell you that I got the whole setup real cheap which is what scares me....

It appears the Comet FNR is getting the boot plus the S-10 CV axles.
Let me know if the Comet is going up for auction.
From my experience with the Comet FNR, I totally agree and I also feel the S-10 axles were too heavy for 13 HP or even 75 HP.
Any idea what suspension design was used with your new axles?
It appears that the inner CV's have a lot of room for axle plunge which is necessary if you retain your current trailing arm concept.
If you go with the 5 link or the RZR style rear suspension you will need very little axle plunge if you place the inboard pivots in line with where the inner CV articulates.
I agree that you should plan ahead for more power in the future.
My plan is replace the 13 HP Predator with a B&S V-twin since my 9 year old G- daughter has already outgrown it on the sand dunes.
Still plenty of power for the dirt.

I hope you are wrong about the axles as I am only going to have 50hp to push them...geared at 11:1.

Well I started fibbing up the new 3 link suspension this weekend. Here are a few pics. Was hoping to get more done.
So time consuming

I will be adding more reinforcement to the main trailing arms. I just got them far enough to where I could visualize how it will all work out,

So here's a question does it matter where the pivot point is on the frame for the trailing arm vertically speaking. I was thinking that it should be level with the axles when they are level but that would put the pivot points up a few inches on the frame, which changes the arc of the arm.

Also based on the pics would it be better to run the rear shocks parallel with the trailing arm or parallel with the axles, either way they will have to be remounted to the outside of the frame.

And the last question would be the inside mounts for the two rear links
From everything I see it looks like the upper link should be shorter than the lower one with the mounting points running on an angle but bisecting the axle where it articulates.

I'm sure I'm over thinking all this but....

Any suggestions would be welcomed

Machined some threaded inserts to weld into the trailing arms. I am planning on using 1/2" rod ends for the two rear links at the pivot points and 5/8 rod ends to connect the trailing arms to the frame. I am wondering if a 5/8 rod end is going to be strong enough though. I will probably use 1-1/4" .083 tube for the rear links since I seem to have plenty on hand or I have 1" .125 I could use
Either way hope to get some more done this weekend.

Those threaded bungs look very nice. I would like to help you with the strength of the rod ends but I don't have much experience testing the different sizes. I think 5/8" will be sufficient although 3/4" would give you peace of mind...

Looks nice. Your sizing should be fine. If you can put the rear heims in double shear it will help - just a bent plate from under the bolt head down to the vertical tube in the rear link on both the upper and lower mounts will make a huge difference in strength.

You're not playing in a sand box, you are going unto the woods...go big now and avoid fixing it later!

Didn't have much time today to do any work but I did get the two mounts for the trailing arms made and tacked onto the frame

Well I was able to mock up the locations of the two rear links, I'm not quite sure of the upper location but was wondering if the camber numbers I'm getting are decent throughout the travel cycle. I have -6 degrees at full bump almost -1 at ride height and a little more than -2 at full droop.

I'm not the camber expert, but those numbers sound okay to me. I was wondering, however, if you were going into positive camber during the cycling of the suspension? If not, then you're probably okay.

01-31-2017, 09:29 PM
Thanks for the reply, nope no positive camber, but should there be some at full droop?

01-31-2017, 11:53 PM
Not necessarily. Once you get it out in the dirt, you'll get a better feel on how much camber you need.

02-01-2017, 10:50 AM
If you keep arms equal space apart on inside and outside mounts, no camber gain. But you can set a neg camber with arms and let it be. Or mount upper arm maybe 1/2" lower on inside mount and have camber gain. Whats you thoughts on having that upper arm mounted out like that? I know strap is temp.
BTW need more threads inside that lower link bar.

The main reason I have the upper mount angled out is because most of the research I have done on the 3 link rear suspension show them that way. I guess it is because if the the upper link is shorter it would create a greater amount of camber gain and loss through the suspension cycle. But I could be completely wrong, this is my first go at a 3 link so any help or insight would be appreciated. The links in the pics are just Temps I used them to try to get the correct dimensions. I calculated the lower link length at ride height, but I now know I should have calculated it a full droop. Hence all the threads showing. I'm gonna use 1.25" tube for the rear links for the final setup once I get it all figured out. I appreciate any and all comments/suggestions regarding my setup because as I said before I'm not exactly sure how this should all finish out.

02-01-2017, 08:16 PM
No, you did it right. The upper inner pivot is at the center of the arc created by the upper outer pivot as it cycles.

02-01-2017, 09:33 PM
No, you did it right. The upper inner pivot is at the center of the arc created by the upper outer pivot as it cycles.

Well that's good to hear, I was hoping someone would say that. I will move forward with current design then. Thanks for the input.

02-02-2017, 08:27 PM
Rear link mounts cut and tacked in place, I have a couple of reinforcement braces I need to add to it, now I have to get the rear shocks mounted. I have not decided weather to run them parallel to the trailing arms or perpendicular. Here is a couple pics of the upper link mount.

New rear shock location.
Well I layed out and cut the new shock mounts, and I am seeking a little input. I'm not to concerned about the lower shock mount as I think it will be plenty strong enough once I add the remaining tubes to the trailing arms along with some gussets, however I couldn't really come up with an upper mount that wouldn't take on some sort of twisting force. I will weld the shock tabs onto the new upper mounts and tie the upper and lower rear tubes together. Also adding diagonal tubes from the lower rear tube to the shock mount and diagonal tubes from both the upper and lower rear tubes to the main frame behind the seats. I have some pics and the red lines represent where the additional tubes will be.

Both shock mounts look great, but it's going to be difficult to get the shock off and out of the upper.

02-09-2017, 01:08 PM
I tend to agree with deaner, plus it looks as if your additional tubing idea is setting up for handling the loading via (for want of a better way to describe it) "pull" control from the bottom side vs supporting the push on the topside. With rear uppers I keep coming back to and using a pyramidal tube structure kicked off the chassis with a plate underneath for the mounts.


Just did this on my daughters


and this one's on mine

Ya I agree with you on the reinforcement from the top I was hoping it would be enough from the bottom only because I think adding tubes from the top will change the look to be less desirable, but function is more important than aesthetics.
Thanks for the input.

02-19-2017, 09:29 PM
Not not much doing lately but I got the rear upper shock mounts tacked in place and checked the shock travel everything seems to be right, I still need to brace the mounts with some diagonal tubes. A couple pics

Looks very cool. I know you changed to a different gearbox setup for ratios, but Incase you do another build for the kids in the future, here's a good gear ratio calculator to help out. http://app.kartcalc.net/#home

It only works on smart phones and tablets, but a computer version is in the works just on the back burner. It's a pretty conservative one in that it recommends a lower (numerically higher) gear ratio but it gives a pretty good idea what you want. I'm sharing it on behalf of the person who made it. Hope it could be of use to you or anyone that uses it.

I played around with the app. It looks like based on the information I put in, I should be somewhere between 8:1 & 10:1. I like how it calculates all the torque and final speeds. Pretty cool. Thanks

No problem, glad it's helpful.

Nicely done,don't think it interrupts the lines at all. nice welds. You could always use the first set of upper mounts as pivot point tabs for a flip up cargo rack that allows access to the fuel tank.

Thanks Xbird.. That's a he'll of an idea for a flip up cargo rack, may just have to do that.

Great build. Fantastic metal working and welds. I'm jealous of your skills! Keep it coming!

Thanks Mcdog. Haven't been on here lately nor have I made any progress on the buggy. Swamped with work and now the kids spring sports pretty much chew up the weekends.

Family and work comes first, while hobbies take a backseat. Well hope you can find some spare time at some point. Would hate to see it get shelved for a long time.
