Hello Wally,
Thanks so much for your help with this project. Your post are very much appreciated. As far as the welding, we just used a lincoln mig welder and tacked the outside piece then the inside piece. Sounds like what you used is a sweet method but we didn't have it available. We just went real slow as to not cause any more warping than necessary. We've completed the welding process on the first window and are working on the second. I'll post some more pic soon. Thanks again. Martin
