    Also big weight difference with tube. As I recall 1" sced 40 is about 50% heavier than 1.25" .095 tube. Also tube is cleaner right from the factory. Some suppliers stack pipe outside and it can be a rusty mess by the time they get to the piece they sell you.

    So, I just priced out tubing and I'll be paying like $6.50/ft.... Sched 40 pipe I can get for $1.44/ft for similar dimensions... that will work out to about $70 for pipe and over $350 for tubing....

    Going .095 wall on the tubing, wouldn't that weaken the structure as opposed going with sched 40 @ .120 wall?

    Glad to see there are fellow Canadians here. Once I actually have something half decent to see, youa re more than welcome to come up my way and check out what I got going on.

    Cheers!

    Mike .120 wall is thick and if you make the whole buggy out of that it'll be heavy. I'm not saying its a bad idea, because it'll be really safe. But many have built buggies with .065" .083 and .095" wall tubing, its all about the design of the frame. I'm currently building mine with mainly .065" wall and .100" wall in key areas because I'm trying to keep it lightweight.

    Really?.... Wonder if I can get away with that. Badlands spec's Schedule 40 in their design will a .083/.095 still work?... I bet that would bring the tubing cost down some to make it easier on the pocket book.... I plan to use a 700r Raptor engine, so weight is definitely a concern for me.... plus, using a 110v welder, welding a thinner tube would be much easier!

    Thanks for the input everyone, I greatly appreciate it.

    Man for sure you"ll get away with .095 wall tubing.
    Even look at Martins build, he used some tubing thinner than .065 wall.
    If you triangulate it properly you can use the thin stuff and it will still be strong.

    That's actually what concerns me a bit, I don't really want to change the design at all so what ever changes I did to the wall thickness would need to work with the current tube layout.

    Trust us here - no NOT use the schedule 40 pipe. Go get 1018 DOM and use that instead.

    Changing this aspect of the plans is not going to affect what you're doing one bit - in fact, pay attention to the other ST3 builds here and you'll discover upgrades, changes, things that the plans fall short on. Use the plans as a guideline, not as the final say. Think outside the box a bit and adapt to make the ride better and yours.

    First place to start in this thinking is getting DOM tubing instead of pipe. (yea, I'm beating the horse...)

    I'm getting the feeling I should go with DOM tubing..... The force is strong with this one....


    Ok, so these are the guys that I am going to in Calgary:

    Apparently they don't carry tubing in DOM1018....

    http://metalsupermarkets.com/metals/...led-grades-cr/

    What should I be getting?

    I am completely unfamiliar with metallurgical terms. Dom, hss, etc. Can someone give me a little clarification on the difference between schedule 40 pipe and dom tubing? Like, is the steel the same and the dimensions are different or are they different blends of carbon steel as well?

    Thanks guys, sorry for the noob questions.

    Oh and I'll be using this to bend this tubing so ideally which ever tubing I go with would need to be compatible with it.

    I think your looking in the wrong spot? Look under online store,

    STEEL-COLD ROLLED TUBE ROUND - Metal Supermarkets

    Not sure if this is your local store?

    You don't want that bender.

    Oh..
    DOM = drawn over mandrel = no seam down the inside
    CREW = cold rolled electric welded = seam down the inside
