I need to scratch an itch!!! I want to build a locost or rather low cost single seat bike engine off road buggy, long travel suspension type buggy. It will need to be of square section tube as I dont want to invest in a tube bender. Anyone have experience of any plans available for such a beast and where I can get them from?

I allways end up looking on here for tool plans but hes got some car build that might suit what your after

You probably better just forking out for a second hand tube bender and then selling it afterwards. It will make life a lot easier and allow you to build a much better chassis.

any good?

These are pretty useless. Bought one years ago and it was known as the tube squasher! Soon sold it on via the local machimery aution if I remember.

I bought it to build a Midlana but unfortunately that project has been cancelled. I've used it on scaffold pipes and it does an excellent job bending those. I agree about the sand filling method for thin stuff but have only done a couple of bends on an exhaust system which worked ok for me. As I said its been little used

Bear in mind that is a pipe bender not a tube bender. Pipe is ID based, tube is OD. Makes a difference to what it will bend without squishing

I bought one of those for our college workshop and anything of thinish wall it simply squashes it as commented. Sold it on hardly used.

There is an off-roader type buggy design by one Ron Champion- you may have heard of him!

No idea if the design is any good or suitable for your needs but would be good to see someone build one!
