Re: Material for Chassis
Excellent advice.
A good joint jig is also used for cutting the tubing. One would use something that looks like a hole saw on a drill. It will cut the tubing at whatever angle you want so tubing ends will mate perfectly with other round pieces.
I think one can get tubing sections pre-bent to angles, 90 deg, 45 deg. etc. The alternative is to take any tubing that you want bent to a muffler shop that has a tube bending machine.
You can use miter cuts to make angles fro the tubing, but it's not as strong.
Finally, withing reason, given the same weight, a larger diameter, thinner wall tube is stronger than a smaller, thicker wall tube.
