well I am about to go shopping for FCH tooling and I see this. do you think this could handle an entire recvr? benchtop blasting cabinet (http://www.use-enco.com/CGI/INSRIT?PMAKA=SL325-0001&PMPANO=0481495&PMKANO=206&PMKBNO=1888&PMPAGE=70&PARTPG=INLMPI) The last one on the page.
BTW, if needed, can't I just use a hole saw and add my shopvac as a dust collector? My grandpa would be saying "You buying a saddle and shoes before the horse," but what the hey.

I have a similar one and found that you indeed need a dust collecting system. If not then the pressure builds up inside and it leaks around the cover plate seals. I can't say that it wouldn't leak if using ALOX grit, but I use glass beads and they get powdered up quickly.

You should not have to cut any holes in it. There should be a vent filter mounted somewhere on the body and you can adapt that to a shop vac. That is what I did and then ran the vac exhaust out of my shop. Still wear the ventilator/filter though. The dust is nasty and can cause bad things to happen in your lungs.

how about size, will it fit most recvrd barrells like AR M1A FAL etc etc.

It would do fine for a receiver, but are you talking a barreled receiver?
My L1A1 receiver with barrel and 5 slot FH attached is 33.5". I would not want to unbarrel a rifle for parking.

I don't know what space limits you have, if any, but if you are going to be parking rifles, I'd want a 36" blasting cabinet like:

Just my non-expert opinion, ya understand! :D

well the diagonal of that working area is 33.3" if you consider for the YZ plane than we talking 35" from upper right hand rear corner to lower left hand front corner. I'll buy it and send it back if its no good.

IMHO, you'd be lots better off with the bigger harbor freight floor unit, and it goes on sale all the time for $199.

You might think about a pusher vent system rather than suction.
Put a muffin fan to push air into the box and a piece of 4 inch flex hose down to ground level for exhaust.
I am going to try this on mine. Its a little bigger and will mount it on a old gas grill frame so that I can roll it out into the driveway.
You can get the fan off any old computer.

Good luck with your blasting

I agree, I got the HF and I'm happy with it, just think it will be hard to work to the corners of the cabinet in question if the gloves will even go that far.
However I like being able to blast a barreled receiver.

Is there a light on that unit?

I got a Harbor Freight unit last year and like it. It is the 36" unit, was on sale for just over $200, and has a light, outlet for dust collection, selection of nozzles, and extra tearoff plastic lenses for the glass window and light. Worth getting the larger unit to take whole barrels. Nice hatch on bottom of hopper for changing media.

Save and wait, I don't know, I'm happy with mine for doing gun parts.
I forgot the trick to the $199, I think I ordered a catalog online and it came with coupons, been a couple years.

No ticks needed, they just go on sale for $199. from time to time.
Sing up to recieve their catalog/flyers and you'll have a heads-up on the sale, plus some will include a 15% off 1 item coupon.
Check out if you have a store near you, then you'll save the shipping too, as there pretty heavy.

If you get one, do yourself a favor, forget about the supplied sealing tape and use silicone instead.
Someone here told me this, but I had already put mine mostly together.
Ended up taking it all apart a few weeks later and siliconing it all together, it made a world of difference.

Cheers, YV

thanks everyone. I guess this will end up sitting in the back porch. I hope not something worthwhile to steal.

You could build a sand blasting cabinet out of wood.
I used some junk plywood to make my cabinet, I used 1 ¼ thick for the top, back, bottom, & front. And I used ½ for the sides, & lid.
http://i43.tinypic.com/oau60y.jpg
It measures 24”deep, 24”high, 31”wide; the lid is 31”x17” @ 45deg.
It was screwed together and glued; after it dried it was sealed with Dap Dynaflex 230
http://i44.tinypic.com/34oemax.jpg
I cut a 6” PVC pipe coupler in two, and used it to make the hand holes.
I bought a pair of sand blaster gloves from Harbor Freight item # 4468-7VGA & stretched them over the pipe coupler ends on the inside of the cabinet.
http://i39.tinypic.com/312iey9.jpg
Two inexpensive gate hinges for the lid.
http://i43.tinypic.com/30djwpl.jpg
The lights are used salsa jars w/bulb sockets screwed inside the jar with 60w bulbs.
http://i44.tinypic.com/1z2hi7n.jpg
http://i41.tinypic.com/2rpweo5.jpg
A vacuum port (with baffle) for removing the dust not sand.
http://i44.tinypic.com/t80rww.jpg
http://i41.tinypic.com/2hfqv6u.jpg
The lid seal is foam rubber weather striping, I used the Dap sealant on the wood to give the weather striping some thing to stick to. I removed some of the weather striping over the window to have a flow of air & help keep the sand from etching the window. (Red arrow)
http://i39.tinypic.com/2d9sq6a.jpg
The window is 16”x6” Plexiglas covered on the inside with a plastic cover made from a plastic page cover cut and taped to the Plexiglas.
http://i39.tinypic.com/wi6p3l.jpg
I use a handheld sand blaster & a small pancake compressor to blast.
And a 5 gal. shop vac. to pull a vacuum on the cabinet.
I took of the rear door of the sandblaster so I can reload without opening the cabinet.
http://i44.tinypic.com/2hckn7p.jpg
It has been a great cabinet; I have blasted a lot of guns and other things.
Total $$ amount about $35
I previously had the compressor, sand blaster, & the shop vac.

can you do a rifle with that thing? I mean compressorwise. Also, can you elaborate on how the dustcover is made and mounted. Thanks. For the money I make I don't think that much more than that is an option.

If you build it long enough you can do just about anything in it.
Here is the air compressor I use.

I didn't spend that much for it, I found it at a local tool show/sale.
It was broke when I bought it; I had to put a new regulator on it.
But other than that it has worked great.
The time it takes me to refill the blaster is just about the same amount of time it takes for the compressor to refill.
The dust cover is a lid from a Christmas candy tin, and I spot welded a strip of steel from a large coffee can. It is used to deflect the sand bouncing off the parts being blasted from going in the vacuum port, and filling the shop vac.
I'm one of those types of builders that try to get the most out of the dollars I spend.
