Re: sandblasting ???
to do Cerakote, you will want to use aluminum oxide, so you will want a cabinet that will allow you to re-use the media as much as practical. You need a cabinet that will be enough size for the biggest part (typically the barrel) you want to blast.

Glass will polish more than etch. The cerakote needs a "tooth" to hang on to

Re: sandblasting ???
You can use a $20 Harbor Freight unit and a small pancake compressor with a filter.
It is what I have and it works fine.
Not optimum.
I am going to get a cabinet to be able to recycle the alum oxide instead of blasting into a big plastic tub.
I need to get a bigger compressor too so the pressure stays constant and not have to wait on the compressor.
YMMV

This is probably a good way to get started if you don't have the money for a bigger compressor and a cabinet. The cabinet also 'helps' to cut down on the dust generated by the blasting. If you don't have a cabinet and choose to use a blaster like this, best to do it outdoors...

Re: sandblasting ???
As an option I have used regular old playsand. Getting AO can be next to impossible sometimes and you have to make due with what you have. After blasting with sand you need to degrease the crap out of it to make sure you dont have any silica dust on the surface. I have not had any problems with adhesion when prepping with sand. If you go this route and dont use a cabinet do it outside with a good mask, silica dust in the lungs is not to healthy.
I also use the harbor freight cheapo gun and running sand at 90psi cuts just fine. Here is a sample of sand at 90psi on a stainless buttplate that is almost done.

I think the Grizzly cabinets would work just fine.

Re: sandblasting ???
In the Cerakote training manual is states aluminum oxide or garnet blast media. I picked up garnet from my local TSC supply.
You can catch Harbor Freight blast cabinets on sale from time to time and use a discount coupon to lower the price even more.

Re: sandblasting ???
just make sure you use a proper mask, not one of those cheap disposable ones. as mr. mackey says...sand is bad. breathing sand leads to silicosus
I use a blast cabinet with AO with a vacuum built in. Even then, I still use a mask and a well ventilated area.

Re: sandblasting ???
I had a problem trying to do this. I went to harbor and freight and purchased one of their sand blasting guns. My air compressor's PSi kept dropping out way to fast. It's a 12 gallon air compressor and I had maybe 20 seconds before it ran out of juice and dropped from 120 PSi to 60 where it wasn't even taking anything off anymore.
Any sudgestion's on a tank that will hold PSi @ atleast 85 PSi that won't break the bank?
Thanks much,

Re: sandblasting ???
Your tank isn't big enough to produce the volume of air required. 120 psi is more than necessary, turn your regulator back to 90 and you'll get a little extra time. I've been running into problems with a 60 gallon tank because It's running so much that it gets hot, and the hot air will vaporize any moisture in the tank. The result of hot air is that it is then pushed through the air lines, doesn't get caught in the water trap and when you're ready to spray the Cerakote, the gun will spit some water. Getting a bigger tank and a two stage pump will decrease the amount of heat and result in a beter product. Until I acquire a bigger compressor, I'm limited to only blasting a few actions at a time and I either have to let it cool or do some spraying which doesn't require much air. There's a few ways to side step the problem of water vapor but that requires changing out hoses and not spraying the Cerakote until the air in the tank is reasonably cool.

Re: sandblasting ???
Even know this isn't my post, thanks for the information. I just learned a lot. How big of a tank is recommended for consistant useage like that? Kind of weird, but you would think there would be a smaller tank that is consistant like that after all these years...
Thanks again,
