Frame question

[BRENT in 10-uh-C]

Yes, for me 0.125" is excessive. If the assembly is mounted onto a fixture and the cross-measurement is equal, then properly heating and re-bucking the crossmember rivets will correct this. When I use the term "properly", the key to doing this process is to use a small concentrated flame that directs the heat into the shank of the rivet. When done correctly, you will find the rivet beginning to turn red on the underside of where the heat was applied. At this point when the rivet is bucked from opposing sides with a great enough force, the shank of the rivet will swell and the top & bottom will tighten as the rivet cools and contracts. Once completed, the frame should stay within the same cross-measurements with minimal twist.
