Thread: Trouble Making Domed/Support Washers

A tapered diamond burr, from Harbor Freight ($8 for the set) in a pin vise will open the hole nicely. Also works well for tapering the hole in the scales to prevent cracking, when pinning.

Here is a pictorial tutorial on making domed collars. I also made a mandrel from a bolt and small piece of brass tubing to polish them.

Here’s the polishing mandrel, just a bolt with the head ground down a piece of 1/16 in id brass tubing and nut.

Polish with metal polish and Chrome Oxide.

That's great Euclid - I'd already used your method of a mandrel for polishing - I now need to find those tapered burrs - we don't have HF over here.

I then take a 4-5 inch piece of bamboo chop stick and dimple the end so it fits over the pin head,( just a bit smaller) of the pinned razor.

Put a dab of .5 Diamond paste, rubbing or polishing compound on the tip, chuck in a drill press and polish the pin head smooth. If you make the dimple just the right depth, you can polish the pin and the washer at the same time. Finish with Chrome Oxide and metal polish.

A block of wood with a dimple drilled in it to hold the pin on the other side, keeps it from dancing on the table, or a piece of 6mm foam.

Chopsticks are handy, I always pick up an extra set.

So how are the domed washers oriented with regard to the shank and the scales?

Peened dome side up, either to fill the hole or domed over smooth.

Ah, silly me. I was thinking about the washers between the scales and the shank. Sometimes they're domed as received. Thanks though.
