Frame rail repair..

Hi all, (and Deuce in particular)

I have some frame rot to repair on my 36 Ford. I bought a 3 foot length of the "correct" frame material to repair a couple of very rusty areas. One is by the body mount, which is fine, the frame there is straight as an arrow. The other area is up towards the cowl where it has a compound curve, up and in. I originally thought about pie cutting (actually just kerf cuts) into the repair piece to get the bow I wanted and then just weld up the cuts. A respected buddy suggested repairing the section with two pieces cut out of a flat sheet. He said you could just trace the curves in the new pieces and weld them together. Which approach sounds more realistic??

Make the repair patches "one piece" if you can. Use a piece of poster board to make your patterns. Cut and form the cardboard until it lays nicely on your uncut frame. When you lay the cardboard out flat it will give you nice flat pattern to cut the patch out of sheet steel.
Trim out your frame and fit the patch to the hole. Weld it in using the skip method and let things cool off before putting to much heat into it and possibly warping the patch or frame.
After everything is welded up get some primer or other type of protective coating on the inside of the rails to cover the welds. The welded areas will rust surprisingly quick if you don't protect them.

Thanks, Mark. The frame in that location is two perpendicular surfaces, the top rail and the side. I think that two seperate pieces is going to make the better looking, stronger, repair.
