I’ll put a value on it, then trade it for materials for future projects of mine. Makes for a paperless deal that works for both of us.

You're bringing back terrible memories! I have installed thousands of those damn things. Lol

Nice custom tooling. Will have to file that one away just in case.

Fairly easy to do. Just remember if it’s something that spins, aim for the centreline, and have relief. If it’s on a lathe then the toolholder will allow the adjustment for centreline.

Basically the same as soldering copper pipe. Clean it, add flux, heat til the solder flows, and let cool. Because of the carbide, just let it air cool until you can touch it, then I’ll run it under hot tap water to wash the hardened flux residue off.

Silver solder comes in various alloys and forms (wire of various diameters, ribbon, sheet etc.)

I just use whatever pieces I have in my toolbox from previous jobs.

The flux is cheap, it’s a paste. It has a tendency to go hard/dry over time, add water and remix it and good to go.

Are these bolts to attach buckets on a vertical belt?

From what I understand that is the normal use. These were being used to replace a knurled, pressed in stud on thin aluminum. Sorry I can’t post a pic of the actual bolt in use.

This job may or may not be a repeat thing, if it is, I have the tool already. If not, maybe someday I’ll modify it for something else. For a couple hours of ‘social distancing’ and basically zero cost, it was a fun little tool to make.

I have a few other tools I’ve made over the years, I’ll see if I can get some pics later today.
