I blasted a jar I had laying around that held loose screws and junk just to test with.  I used Black Diamond 40/80 media. Running my hand over it you can slightly feel it and its pretty frosting looking. How would a AO compare and a higher finer grit ?

I stared with the number 5 nozzle that came with the cabinet. (The TSC bench cabinet.) Its hooked to a Porter Cable pancake compress. The hose is like 25ft or more long. Will get a shorty one (or does that matter in terms of pressure reaching the gun ?).

When I started shooting the compressor came on and I wasn't expecting it and damn near pissed myself. Started me. It worked. Yea.  I did have a hard time seeing in there after blasting for a few minutes. It doesn't appear as if there is a film over the top or the piece underneath the top ? Do they normally have them on ? 

I forget in my excitement to lock the lid down. So couple time got hit in the nose with media flying out. The lid was down just not locked.

I checked while shooting and the compress was doing about 50-60 with the gun going. Good bad or okay ?

I used Imprintables Duracal 530 to make the stencil with. Was a eagle head. I wanted to see if the detail would show up like the eyes and the lines of the feathers. Seemed to. I could have done the eyes better. The vinyl held up great.  The media didn't pierce it or tear it off. And its like $12.50 for a 15"x10 yd roll.  I put the heat gun to it for like 15seconds and was able to peel the vinyl off and didn't leave any glue reside behind. The painters tape tho was a pain to get off and left a residue behind. I removed it before I used the heat gun.

I did not tape off the back of the jar and changed the nozzle from the number 5 to the smaller 4 and blasted the back to see the difference. The smaller nozzle seems spotter in the etching. Seems like I can see the media shape or tiny tiny circles. Is that from me not blasting long enough or too long ? Or is it the nozzle characteristics ?

My tools rust out in my shed from the Florida humidity can the same material be used to remove the rust or should I or do I need to change it out when doing rust or paint removal ? And for those what material is better to use ? Glass beads ? I seen that at TSC also. 80 grit I think.

I can see how you all get addicted to this. Wife won't be happy if she comes home and finds all her glassware blasted up.

THanks

Looks good! I use the 40/80 in my cabinet at all times, etching, rust removal, etc. It's a good all around media, IMO.

Looks like you had a little resist failure in a few spots, are you keeping the gun back a few inches from the surface? You don't have to be right against it for it to etch.

couple times got close. also in a couple places near the top the vinyl was pressed good against the jar. Since I was just trying to see if it all worked I didn't worry about it.
GOing to the dollar store to get some glasses tomorrow to play with.
Thanks

Your fun has just begun!!!

Hey Mark,

50-60 is good, you can always start lower, see what it does and work the pressure up. That's around what mine is. Question - When the compressor comes on is it instantly, like when you first start blasting or after a min or so after starting? You may want to look at a little larger one. Just my 02. TSC has a 26 gal, Job Smart compressor, works really well. I can do one wine bottle before the compressor come on.

I'm not familiar with the mask material you're using, sounds pricey. Regular vinyl and painters tape work great, never had any issues with getting it off. No heat gun needed. Sounds too much like work. Wrap the glass in saran wrap to protect the unmasked part. Cut a window where the mask is and tape around it.

So is the Black Bull media AO?

Now, I'm not trying to be a D*&k or anything but....

I've done this to  . But where's your respirator? If ya had one on it wouldn't hit you in the nose. Ok, last time I mention it.

You might want to hook up your shop vac to.

Have fun 

So on the TSC bench top cabinet how are you hooking up the dry vac. ? Or what size are you using ? My hose is like 2 inches round and way to big. I guess I could cut a hole to make it fit but rather not. And I assume it would go on the side were the triangular filter is ?

Yea will get a respirator forgot to pick one up and was too excited to give it awhirl. In fact when to the dollar store and got a bunch of glasses and bowl and ashtrays to practice on. Yea for Dollar store !

Here's a link to a post from kyjeeper. It shows ya what he's talking about. He's got it covered.  

@ kyjeeper or anyone else - Do you know if the Black Bull media AO?  Huh?

Sorry, I meant to post the link with that, thanks!  

The Black Diamond media from TSC is Coal Slag, not AO.  

Here's their website with more info and MSDS.

That's what I thought. Thanks for the confirmation. 

If the TSC cabinet is like the Job Smart cabinet, it goes on the side. Where the filter is.
