Hello Joe,
I found what Mike posted, does anyone have photos?
Michael Orlen:
Soldering a shim on the hook has gotten a very bad name, due mostly to the "coke can shim", the aluminum shim, the brass shim, and the feeler gauge/glue techniques. When done carefully, the process includes block sanding the hook using a correct size of round stock in order to make the hook surface "round" again. It is then tinned with lead/tin solder (acid core will work best) and the correct thickness of mild steel shim stock is clamped in place (again, using a piece of round stock that fits perfectly) and the hook is heated until the solder flows. The excess shim stock can be easily trimmed off with a mat knife and file. The soldered area must then be soaked in baking soda and water, in order to neutralize the acid in the solder....this will prevent after rust.
