More on the Steering Story
--- managed to get the final pieces cut & the plate for mounting the steering gear box installed today. After a bunch of checking & rechecking I decided to go ahead and weld that sucker in place.
Here is the fishplate notched, prepped & beveled.
And a couple of braces fabbed from some 1/4" flat stock. They will weld to the plate but bolt to the frame.
A final test fit of the gear box after tack welding the plate in place.
1/2" thick mounting bracket fully welded.
Reinforcing braces on the inside. They are welded to the plate, but bolted to the lower frame rail. All of the welding was done on the fishplate...not the frame (see below).
I try to keep welding on the frame to an absolute minimum. These older rigs were built with different metallurgy and a totally different design concept on the frames. Stiff suspension paired with a flexible frame. After WWII they went the other way...rigid frames and soft suspension. Too much heat in too many places can cause pre-war frames to fail so you are better off bolting or hot-buck riveting. And since I don't have a hot-buck set-up...mig it is.
Also, any attachments, bolted, riveted or welded (newer frames only) to any frame should be made to the top or bottom rail of the "C" channel only. Never drill through any portion the vertical section of the frame. Chevrolet and other makers have put out a number of bulletins about this, but many folks are not aware of them.
Back to work.
