Hello Tom and Brady!
Thanks Tom for the information on the aircraft steel. That was all new info to me since I don't have metal working experience.
Thanks Brady for the added direction. The welder will be welding my X-car as it sits on my machine, as getting welded up and then finding something is off is the scariest part of this project. The tubing I bought is 3/16" thick, though I have to check my threads and my tap set.
As to the blue paint, I am afraid I messed it up with all the filing I did to get rid of the cold-formed edge burs. (Had I just needed to file a few feet, I could have kept it nice, but I had to file every rail, on both sides, and got sloppier the more I filed. )
Thanks again, Chuck
