Repairing a Broken Lift/Slide Mechanism

The right side lift/slide mechanism had a crack that weakened the whole assembly.  Fortunately it didn't break completely in half.  Notice the crack beneath the roller in the center of Fig-1 and from the bottom in Fig-2. 
To repair, I thoroughly cleaned the part with lacquer thinner and sanded the surface to be repaired.

I then cut a piece of flashing material to fit over the damaged area and made sure it wrapped around the edges.  I mixed up some J-B Weld and applied it to the surface of the damaged area the size of the patch.  I also worked some into the crack.   I then filled the the hollow area between the side with the crack and the undamaged side.  Fig-3  I made sure all the slide surfaces were clear of the epoxy and none of the repair will hinder the mechanism operation.
Hopefully, the patch and the epoxy that filled the area around the break will be strong enough to hold up.
