Default Bead blast recipes?

I'm wanting to bead blast an sp101 and I know different bead sizes at different PSI's will give different shades of matte finish. Anybody ever experimented with this enough to know what will give me the darker grey color I see on some bead blast jobs?

Default Bead blasting......

Not so much the material you use in the blasting dept.....What type of steel are you working with. You can use fine sand, glass beads, and even walnut hull......Are try baking soda and water blasting......What is this dark coloring your referring to.....

This could go wrong quick. I'd stick to some of the least abrasive media, maybe walnut shells, or soda. Did you know that if you loiter too long in one area, you will warp whatever you are blasting? Granted, it's worse with thin sheet, but a gun has some tight tolerances.......

I'm going for a darker matte grey like this

I've seen some on here at FTF talk of blasting their own guns. And from what I've heard it seems ti be a project you can DIY if you have access to a blaster. Maybe I'm wrong.

But it's stainless steel as is with a brushed finish but I much prefer matte finishes.

You will bore yourself to tears trying to achieve the finish you want on SS using glass beads, walnut hulls or soda.

You will need to use something like Brown/White Aluminum Oxide, Silicon Carbide, Carbon Cut Wire, Cast Stainless Steel Shot or Steel Grit.

Media material, grit size and blast pressure will give you many choices of finish.

^ This finish was achieved on my SS Colt XSE using a relatively aggressive aluminum oxide at 90#. A less aggressive grit would produce a matte surface finish.

What grit would you recommend for a smoother looking finish?

I use #8 medium glass beads when I want to take off the finish but not etch the metal. Aluminum oxide will etch the metal and give you a rougher finish which is good if you want to follow up with DuraCoat or Cerekote finish. I've never used walnut media except in my tumbler for cleaning ammo brass for reloading.

The real trick to getting a good finish with your blaster is to have a compressor that will maintains about 10 CFM at 100 psi. I really think you want the finish that the glass beads give you for your stainless firearm.

I must add that I change out the media in my cabinet depending on the finish I'll be going for. If I will be applying DuraCoat or Cerekote, I always use aluminum oxide. If I am bluing, I always use glass beads.

Hope that helped ya...
