where to find lapping compound?

[crout]

I'm looking for a place to buy some lapping compound. I only need like 1 tsp to touch up a barrel crown. do i have to order it or can a pick it up at a local machine shop or hardware store?

Try an auto parts supply. Ask them for valve lapping compound.

automotive stores should have fine and course valve lapping compound. Clover brand used to be in a double ended tub with course at one end and fine on the other. For a very fine abrasive, Simonize with red jeweller's rouge.

Lapping a crown...? I thought that method stopped being used 50 or 60 years ago...

Seriously, have it properly machined.

so how do you finish off a crown once it's been re-cut??

just cut and let er rip?

I'm just trying to smooth out some small blemishes. if it works great if not. off to a gun smith.

"...small blemishes..." How small and are there any cuts/dings in the metal? If you cut the muzzle, it needs to be re-crowned. Brownell's sells the tool.
Fine tool marks can be buffed out with a cloth wheel and jeweller's rouge.

so canadian tire has lapping compound 120 or 240 grit and non of the auotparts stores knows the grit of their valve grinding compound. i guess i'll go and raid a machine shop.

After machining it as smooth as you can I finish the crown with a 60 degree removable piloted reamer. It leaves a burr free smooth finish.
