Re: 58 3100 cab rebuild
Using the template I scribed the new parts on a 14Ga shhet of cold rolled mild steel. Netsx is cutting them out. I used a plasma torch so I could get nice clean cuts. Next is drilling the holes and drilling the reliefs for the bends.
Pic 1 is the blank roughed out pic 2 is the plasma cut pic 3 is the drilled bolt hole and bend reliefs pic 4 is cutting the front bend reliefs on the band saw pic 5 is a finished blank ready for the bending. Last edited by dwcsr; 11-20-2007 at 08:48 PM. |

Re: 58 3100 cab rebuild
The tricky part is the bends. I can't tell you how many time I've bent these pieces backwards and made junk. It may be helpfull if you have an orginal to use as a guide.
The first bend is the part thst welds to the front of the pillar post. The second bend is the part that welds to the hinge pillar panel. The third bend shapes the top portion of the bracket If you didn't drill the bolt hole out you can do it now. 3/4" hole saw works great. The relief holes are 3/16.

Re: 58 3100 cab rebuild
Now for the bottom part. We need to make a curved triangle to form the underside of the bracket. This can be done on a brake or on an anvil. Its much easier on a brake. I made some guide lines on the triangle piece so I had something to follow while bending.
The reason for the lines is that this piece is an odd shaped triangle and we want the bends square to the short side with the notch. If you follow the bottom it will curve left or right while bending top curve. This bracket when done will look cockeyed but it actually goes slightly outward in the front when welded in place.

Next is the weld up. Make sure you bevel the mating edges. This way you can grind smooth the weld and still have good strength in the joint. After beveling you need to do the final fitting and clamp up. You'll need some small clamps and a spacer of some sorts. I used some machining wedges.
Run the bead on the outer edge and don't weld the inner side. Clean up the welds and finish the edges and your done. I also use Bloxide weldable primer to coat them. Last edited by dwcsr; 11-20-2007 at 08:56 PM. |
