Diana Burnishing with Scotch-Brite

[Sudz]

I'm rebuilding my older D34 which has an older Vortex PG2 kit installed. I have seen a recommendation where it is suggested that burnishing the compression chamber bore with a Scotch-Brite pad is a good thing when coupled with a very thin coat of Moly. A red Scotch-Brite pad is rotated to create a very fine crosshatch in the bore. Afterwards, a fine burnished layer of moly is added to the bore. Key here is very little moly is used.

Sounds like a good idea but is it? Is this a common practice among springers?

16 inch or so Wood dowel , 3 inch circle counter screwed in to top holding scotch bright in with nylon washer to guide on the breech face. Drill center hole in rear for blind peg to grab with drill . Spin away back and forth creating a cross hatch pattern. 320 to 400 maroon. Pad. Works great. Molly can be used after doing it raw.

It's kind of a hone and leaves bare metal for the moly to stick to. While I cannot speak directly about your gun, this is a practice I use for similar applications. There's finer scotch Brite than the maroon that I might be tempted to use, 2 shades of gray if i remember correctly. I've used this on main tubes of old pumpers.

Another alternative is a old wheel cylinder hone <fine stone.

I was afraid to get that specific but good point.

Using scotch bright like a ball hone I cut a slot in a dowel to slip scotch bright strips into and form a sort of cartridge roll and chuck it up in a drill.

I’m in the middle of installing a Vortek PG4 kit in my HW95 and was considering honing my chamber or not. Off to the store for some Scotch-Brite. I have some green stuff, but it’s pretty benign I think.

Great input guys. Good to know I'm not breaking virgin ground on this. I was concerned about the moly detonating even though we're talking about a very fine burnishing of the stuff. Apparently that's not a concern.
I'm moving forward with this process as my plan.

Think i will look for a "beater " HW gun at the next show to start down this path of "fixing guns" . Although i do have a NIB HW50 i got for 1/2 price ??

The maroon pads can be used to touch up an actual hone and produce a terrific surface finish. It will cut less aggressively and flush a bit better if done wet. Messy, but mineral oil, spirits, kerosene, or even good old WD-40 would be my preference over running dry. Also the pads shed fibers like mad, so be sure to clean very well after.
