Since the clutch part is so difficult to find it seems, I'm wondering if I should just put weld into the pits and sand flat... ? Bronze or Mig Weld... Bronze seems easier, but wondering if the heat would be too much & warp the rest of it Mig you can put in random spots, and wont heat up as bad Thoughts?  |

That’s what I’d call taking on a challenge.
Ever try TIG brazing? More localized heat input than oxy/acet brazing. Melting point of the rod is around 1800/1900 degrees , would provide a little margin between the rod to flow and the base steel melting. Relatively easy to grind flat. Large backer plate to help stabilize heat might be in order.
I’d sure hate to blow a hole though the sheave...
Good luck.

Good points. On top of being nearly impossible to not wreck by over heating, it almost certainly go out of balance too. Might be far better to hold out for a used non rusted out sheave

I think my new plan for this is to take the pulley all apart and bead blast the surface of the pulleys. Then clean them all up and try using JB weld on the grooves. Plan to use a high speed sander while spinning the sheave to get it smooth again. If I ever find a better pulley that will be an easier fix, but the cold weld is my new plan.
Just about got the engine ready to fire for the first time in a LOT of years...
