    Take into account spring back as you do this. You'll have to "overbend" the arms to get them to fit correctly.

    Thanks. The bottle jack trick worked awesome stretching out the arms to fit the mounts.
    I been visiting family so not much progress.
    Got out and started working on the rear shock mounts this weekend. Probably shouldn't weld anything in permanently until I get an engine and get more weight on them.
    The steering rack I purchased from the guy off-loading his buggy parts and plans is still too narrow for the plans to prevent massive toe-in at full bump. The rack is 14" wide but the suspension pivots are 20.5" apart. I'm thinking of using the small rack to drive a pseudo rack made of telescoping tube to correct the steering geometry. What do you think?

    Got some time at the lathe today and was able to turn some parts I'm going to use for the center spool in the rear end of the buggy.

    Tacked in the brackets for the rear shock mounts. The springs seem a bit stiff but I still need to build the back half of the cage, plus the weight of the engine, coolant, fuel, etc will probably even it out. The shocks are off a late 80s, early 90s Honda CR 250's and the price was right so we will see how they go.

    Also got a bit of work done on my steering system and re-did some work on the knuckles to improve the akerman and the mounts for the tie rod spherical joints. I added a grease zerk to my pseudo rack/spreader and found some generic dust boots at Auto Zone that should work to keep the grease dirt free.

    I would suggest staying away from the the spreader idea unless it's an absolute last resort method. I have the opposite issue, in needing to narrow my tie rod mount points. I've used a spreader in the same manner to achieve this and have battled issues with it for 7 years now. you'd be better off extending the rack length by welding an equal diameter extension to either end of the shaft with drilled and tapped ends for the clevis. There's too much rotational movement between the rack shaft and pinion teeth for it to be as simple as it looks. I've had to sandwich my spreader to lock it in place with my latest version of it to prevent it from rotating upwards and toeing in when it pulled the tie rods up with it. My original one hung underneath and rotated down/rearwards and i had a delrin-type block to act as a stop. shaft teeth end up riding on their end edges, contacting more on an angle and wearing.

    Well I looked into my rack more and it apparently had heim joints that screwed into the end of the rack so all I had to do was remove them and build new clevis ends that extended out further and it looks like it will work perfectly. I also got the tie rods built and attached. Pretty much eliminated my bump steer.

    I also bought some 1/2" drive impact U-joints from harbor freight to use for my steering. They only cost $7 for a set of 1/4, 3/8, and 1/2" drive and if I got one joint for a buggy from a place like Kartek it would be $30 for one joint. I'm sure using the impact U-joint for steering will be a much easier life than its intended use, so I'm not worried about it holding up.

    Coming along nicely. Please be sure and weld in some support bars at the bottom between the front A-Arm mounts. I see you have an X-Brace, but you still need some support or those bottom rails between the arms... lot's of forces going on up there. Same with in the chassis area for seats etc. I built a panther way back in early 2000 with a R1 motor in it... I braced the snot out of it to keep from flexing.

    Thanks. I planned on adding another brace between the lower A-arms to give strengthen it and allow a better mount for a skid plate up front. More bracing will come elsewhere when I get some thinner wall tubing as well.
    Was hoping I would be further along by now (which everyone says about their own builds) but with my high school kid not helping like he said and life getting in the way it happens.

    This weekends progress was me picking up a motor for this buggy. I bought it from Kuma here on the forum. It's a GSXR 750 he used to have in his buggy. Kuma, Great to chat with you and show me your buggy too. Thanks

    Ah, excellent. I always like hearing that MBN members have helped each other out.

    So I guess that's a true "crate motor"? It's even quality checked!
