Anybody got a link to a semi-durable 2-seater off-road-type go-kart made from PVC tubing?

I'm looking for something the boy and thier friends can build, doing 80% or so of the work themselves......Its not much fun for them if I have to haul out a welder and do it all while they stand around and watch, so SCH 80 PVC (with aluminum tube insterts where needed seems like a pretty good alternative to steel for something they can cut and assemble themselves.

It needs 2 seats for a total load of about 180-200 pounds of kid. Its easy enough for me to come up with a basic chasis design, but some areas like steering linkages and live axle/power couplng (chain/v-belt?), suspention ect that I could use a little study time on. Once its done the idea is they can use it around the fields and trails in this area, so it needs to be more-or-less along the lines of a Honda Odessy.

PVC?

I dunno man....

even with alluminum inserts there would be little hope of re-enforcing the joints...


1 good whack, and they may end up with a sore bumm....

ABS would probably be good... although I think it's not as strong as PVC, but it also doesn't shatter... An important feature when you crash into something.... and you know they'll crash into something.

I dont think id trust pvc, unless you filled it with foam and wrapped it in carbon fiber.

I still wouldn't trust PVC. When they hit something and the PVC breaks, there's a very good chance of them getting impaled with what's left of the "Go Kart". PVC doesn't break off nice and clean, you know.

It might be boring for them to sit around and watch you weld, but I wouldn't sacrafice my kid's entertainment for safety.

The kids wouldnt be touching THAT !!

These guys have PVC-framed peddle cars http://www.americanspeedster.com/ , but thier wheel/suspention setup is totally unsuited to the terrain around here (farm fields, ATV trails and gravel roads). It would be easy enough to adapt a 5hp motor to thier car but it still leaves the running gear issue.

When I said PVC with aluminum, I'm thinging more in terms of the tube/gusset method used in ultralight airframes, The main frame would be aluminum tube inside the PVC tube, with the PVC more or less acting as a "coating" and an assembly aide, and a secondary structual tie-in, Once the frame was assembled and glued, gussets of 1/4" aluminum would be bolted to the sides of all joints. very light and VERY strong, for the main part of the chasis anyway. The superstructure would be just plain PVC (or ABS) to save weight and cost......AND, I just happen to have about 20 pieces or so of 7 foot by 2"/.063 wall 6061-T6 tubing laying around as cut-offs from wing spars on my past projects .........All stuff the kids can cut with nothing more than a hacksaw and a cordless drill.
