How Do I Shorten an Antique Truck Frame?
How Do I Shorten an Antique Truck Frame?
(OP)
I have a 1941 WWII Dodge pickup truck. I found a perfect ambulance frame for it, identical but 7" longerin the center section. I have been told I can cut it at a 45 dgree angle and mig weld it back together. This would be done about center of theframe, between the axles. I want to keep it "original" so don't want to add gussets. It's built in two layers of steel, about 3/16" and 1/8". I don't think these old frames were hardened. Will this hold okay? Should I have a certified weldor do it?
Also, is there any way to replace the large factory rivets to replace cross a memeber? Again, I want to keep it as close to original as possible.
I would appreciate any expert advice,
Maurice

Cut the frame at a 45 deg angle, as much as you don't want to I would definetly consider using a doubler (fishplate)if it's a single frame. If looks are a concern, can't you put it on the inside of the channel, this would work if it was a single frame.
You said yours is a double,if you can cut both frames so the cuts are not in line, you could probably do away with the doubler. It shouldn't be hard to cut the frames in a different spot as the rust accumulated between the rails should prevent any inadvertant damage to the rail you're not cutting.
As far as rivets go, if you can't find rivets with the appearance you want, how 'bout carriage bolts, not an ideal solution but....
If you're not used to welding, I would consider getting someone that knows what he's doing, after all, if the frame breaks, think of the consequences...Mike

Blacksmith---I have even welded one section (MANY years ago) with gas and it worked ok, not great, but ok! Never brazed one--- A lot of tubing frames on race cars have been brazed together for about a hundred years, though.
