I have a sheave set (2 piece roughly 24" diam) coming in that is cast C86200 alloy and is used on a king crab pot hauler mgfr by Marco Global. It has been trimmed so many times over the course of the years that there is nothing left to trim. My thoughts are to build it back up and machine back to original spec. Having never done a buildup on any kind of bronze, I'm seeking some feedback from someone that has. Silicone bronze mig wire is readily available but manganese bronze is pretty special. Any info coming in would be greatly appreciated as to weld procedure, optional alloys, etc. thanks, chip

Mick,

It never ceases to amaze me how much widely varied knowledge is available here, just by getting a bunch of folk with widely different backgrounds and skills in one place under such a seemingly work-a-day theme as welding.

Hey,

It really is amazing when you start to dig around, what you find.

Thanks for the input. I'm planning a contact with a local "flamespray" outfit here in the Seattle area to see if this is something that they've done before. So far, no one that I've checked with has ever done it. I believe there are many propellers out there with this alloy that have been repaired sucessfully and will check with the big prop shops as well. chip

Hey there,

That Metal Surgery joint has a process called metal brushing. Its is akin to electoplating but is used for build up of shafts and such. That may be suitable if your part is not tolerable of too much heat.
