Bruce,
Yeah, that makes sense why not to use the PVC. By necking do you mean how some benders turn the tubing into an oval with a ridge?
This is the bender I have, have you ever used anything similar? If I use it properly with lube and have everything clean it should work right?
I'm a little confused though about what you mean with the bracing, should I brace it so the braces are running through the cage and not hitting any tubing? I should be building the cage inside of the car right? Not off to the side? Also what did you mean by hold it safely in the corner? Am I right about tacking the whole chassis together in the car then taking it out to flip over and weld? Or do you usually fully weld it while it's in the car? If you seperate the tack welded chassis from the car to finish welding it and the braces are running through the cage you would have to take the braces out. And that would be bad? And your saying it's best to remove the doors right before putting the body on the chassis for the final time? I was wondering why it's better to take them off instead of leaving them on.
Thanks a lot,
Michael
