i am going to take a few inches of an old 10/22 barrel
i have watched a video on youtube from MidwayUSA where they use lapping compound on a coach screw to crown the barrel (dont laugh ! lol)
as its an old barrel i dont want to spend loads getting it done professionally, as its only a wee gun for plinking with
so here is my questions......

1. where do i get lapping compound to do this ?
2. what type do i go for ? smooth, medium or coarse etc ?
3. is it possible to buy it in small amounts, as i only need a teaspoon amount ??

i know someone out there will be an expert at this

cheers
 
Local car spare place should have it, all you need is fine.
Round here the cheapest way to get it is a kit, valve lapping stick and 2 tubs of compound, fine and course, about a fiver.

Valve lapping compound is a little too coarse (even the fine). Best results are from Diamond lapping paste on a soft Brass or Aluminium lap.
Readily available on the evilbay. The pastes are generally from 40 micron down to .5 micron.

IIRC rinkydink kit for around a tenner...

Just one thing, do not use different grades of abrasive on the same lap.
