Gunsmithing a little tip for bead blasting.

[300sniper]

maybe no one else has this problem when bead blasting stainless for a matte finish but i sure have. i would blast until it looked great in the cabinet and then when the part was brought out in the sunlight, there were obvious shiners. the part would have to be put back in the cabinet and hit where i thought the shiners were. again, when brought back into sunlight, i'd see more spots i missed.

i had a barrel to do today and had an idea to coat it with dykem before i tossed it in the cabinet. it made it really easy to keep track of where i'd been and where i needed to blast. by the time the dykem was completely gone, i had the finish i was after.

if you don't have the problem i have been having, disregard this. if you do, you may want to try it next time.

and some pics just because.

I usually hit the crown with corse alox at 135 psi to debur it after I shape it with a rat tail file.

Which font style and cutter type did you use on this barrel?

Thanks,

Dennis

Re: a little tip for bead blasting.

The font is called "complex" in my control. I used a 1/4", 60 degree carbide engraving bit. The letters are .125" tall and .009" deep.

Re: a little tip for bead blasting.

Bert,

Better lights, better dust collector, and routine replacement of the glass helps too.

Saves from buying spray cans of Dykem too all the time.

Just admit it, your huffing the chit.

Re: a little tip for bead blasting.

I just picked up a new skat with dust collector. It's gotta friggin' flood light in the thing.
