Blast Cabinet ??
I'm working on the interior layout of my shop.
Does anyone ( DIY'r ) have and use a blast cabinet in their shop ? I know it needs compressed air. Does it need a dedicated vacuum also ? How messy are they ? I'm looking at the under $300, stand up one at Harbor Freight. www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=39170 Thoughts ? Suggestions ?

Those blast cabinets recycle the blast media. it is picked up by the gun, the blasted on the part, then picked up by the gun again.
This goes on until such time as the blast media has been contaminated, and all sharp edges are broken off the blast media. You dont need a vacuum or filter system with a cabinet like that.

Cary,
I bought the dual door model from Harbor Freight and it works fine without a vacuum. Got the one that sits on a bench and assume that you are looking at the freestanding unit? After using it for three months, cannot live without it now. So nice to have clean parts to work with... Joe

a vacuum would be nice, but it won't come with the small ones. get one with a fan that pulls out the dust into a bag, so you can see better. new bead will be pretty much dust free, but as it gets pulverized and mixed with contaminates, that's when you'll wish you bought the one with the fan.

not familar with the harbor freight unit as i have the 960 model from tp tools. http://www.tptools.com they have smaller less expensive units available as well as all supplies you need.
aside from my welder its probably the tool im most happy with. i use it everyday. make sure your compressor is up to the job, no matter what size blaster you buy. mine has a vacuum and dust colletion. it isnt messy at all. the only mess i made was ripping open the bag of glass beads. i've used it for wheels, engine parts, and tons of other parts. i built a frame with casters to easily move it around the shop. im on my third car rebuild/restoration and its paid for itself in use and time savings.

I have a TP too, and it works fine. What JW said about dust is true, although some media create more dust than others. To blast you need the gun with two tubes attached to it. One is air supply from a compressor, and the other is the siphon tube. You can blast without a cabinet directly from a bag of sand if you want to. With more expensive media, recovery of same is most desirable (read that a blast cabinet). A hole in the side of the cabinet with a vacuum fitting helps to remove dust, but you need an ultrafine filter bag to protect your vacuum cleaner motor.

I bought a Harbor Freight benchtop several years ago. It was a cheap one, and it leaks glass beads out of the bottom seams. Not a problem unless you move it around. If you get a cheap one, I'd recommend sealing the cabinet seams from the inside with silicone caulk before you ever use it.

In general the shop vac won't pass enough air to keep the dust down in a large cabinet. You will need to use some dust collector type of external bag thing. Harbor Freight Tools, Grizzley etc. even Home Depot and Lowes carries them.
The sealing of the cabinet with silicone is a good idea also. TP tools carries one of the most comprehensive listing of replacement parts for sandblasting guns and cabinets. They send free catalogs too! The combo that I've chosen is the $199 harbor freight big cabinet on sale and a good TP gun for the thing. I will use it with a large 1-2 hp dust collector from Grizzley. It will take some experimenting on where the good placement of the vaccum line to the collector. good luck, David Duffield |

Can you give me a little more info on the dust collectors ? It is like one of the systems they use in wood shops ?

Make sure you have enough compressed air capacity planned; these bead blast cabinents require a lot of compressed air. Jim

Jim's comments are correct.
I found an extra 30 gallon air compressor tank on Ebay and hooked it inline with my compressor and that helps. Can blast away for about 5 minutes then have to stop and let the compressor catch up. Sure signs that I need a bigger one. Still, cleaned off two strut assy's and one SU carb last night in the cabinet. Could not live without it now... Joe

Will my 30 gallon 6HP CRAFTSMAN run a small bench top blaster?

Chris,
Your compressor will run the cabinet, the question is are you going to be doing any extended cleaning or do you mind stopping every 5 minutes to let the compressor catch up? Once you get used to having one, its hard to go back. Nice clean parts are very nice to work with... Joe

I am thinking small parts...anything large I'll take to the NAS auto hobby, they have a large SnapOn unit that I can but a front bumper/wheel etc...into 3 bucks an hour. My intention is to clean up stuff as I take it apart, get rid of grime etc....

I'm wondering about this vacuum issue. If the vacuum runs while blasting, wouldn't the glass beads be carried out of the cabinet, when you actually want them to stay IN the cabinet? I could see running a vacuum for a few seconds when you're done blasting or want to check your work, just to clear the air so you can see things.
And yes, a 6hp / 30 gal compressor will do the job. Like others said, you might have to stop occasionally to let the compressor catch up. |

Wavey,
There is a cone filter on my unit. Vaccum hooks up there and clears the dust but the particulate matter stays inside the cabinet. Have not needed to hook mine up yet... Joe

Old porsche is correct in recommending a dust collector if you are going to use it a lot. The shop vac will help clear the dust from smaller projects. It does get very hard to see (a light inside really helps) through the dust. It is worth while considering some of the media that create less dust.

Here's the compressor I'm looking at getting. Nothing fancy.
This should be big enough for one guy, shouldn't it. www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=32357

Cary,
You are a sick puppy... thats why we like you! Can I move in and be the "gofer?" I would think that this compressor would handle almost anything you threw at it, including 3/4 impact wrenches! joe
