Thanks guys! Flattery is always welcome.
Dennis, you are right, it
will warp. There are 2 things to do then.
- Don't put in more heat than necessary. That's why I use TIG here.
- Take out the shrink as you go. That's done by grinding down any weld beads and hammering the weld against a dolly thus stretching it. The hammering must extend over the heat affected zone, it's recognized by the blue color. But it must be done with some care. Too much will stretch it, which also warps it. Your best tool here is your patience IMO.
If you're interested in this, you should go to
Metal Meet Forums - Powered by vBulletin where you will find people with far more experience in this than I have.
However I do not recommend you cut up your trunklid as your first job.
