How to improve my cabinet blaster

I'm blasting some parts in my cabinet blaster and the slow pace is killing me. I have an inexpensive floor based suction blaster from Northern Tool. I've already gone through troubleshooting it and I think it's just slow because it's cheap. I'm pretty sure I read a post some time ago about how you can add a pressurized tank type blaster to a standard suction blaster to improve its efficiency but now I can't find that post. Is it possible to do something like that? I don't do that much blasting, but if I can't get this thing to improve how it is working I'm going to go crazy! If there is nothing I can do to improve this thing can someone recommend a good affordable (under $1,500) cabinet blaster? Thanks.

Hey Mike I was having the same problem with my cheap blaster that I bought from harbor freight. It turned out I didn't have enough CFM out of my compressor that I had. My home one was only putting out 6.5cfm. I took my blaster to my buddys shop which had an industrial type compressor putting out well over 20cfm and man did it BLAST. Then I NEEDED to run a vacuum to actually let me see in the cabinet. Somtimes flow is also slowed down by the type of media you're using. I like baking soda but it doesn't get rid of rust just paint and filler. But I had almost not flow with some plastic media I first used. Good Luck man

It doesn't sound like you have much of a compressor. That's your first major hurdle. Upgrade to this, as a minumum. It's all about the CFM when it comes to blasting. Once you have a compressor of this size, unless you're running a business, it's probably the last one you'll ever need!

Here's a couple of suggestions for a good blast cabinet. CL is loaded with good stuff!

Then of course there's the Barrel Blaster..................

Media choice has a big effect as well..I use vitro grit which is crushed glass and that stuff cuts well at lower pressures and volume..Makes my little spot blaster work just fine..

My compressor is big enough, My home made cabinet,big enough to blast a rear end, has a sloping bottom and reuses the media with the bottom suction hose. I have read here on HR to get your bucket of media at least as high as the gun so it doesn't have to lift the media up the hose. I usually pressure wash and solvent wash everything so I don;t get globs of greasy mud in the blaster.

And, just to stir the pot.. DON'T buy that compressor.. Trust me, I was going to. :D

OK, pot stirred! I own the SS5N5. Same compressor listed except for an 80 gal tank. Bought it new from TSC in 2006. It gets used almost daily and I haven't had a problem with it in 5 years! I've heard that some have had issues with the compressor motor but I've had none. Maybe I'm just lucky. Anyhow, great compressor. Runs my 90lb pressure pot blaster, blast cabinet, air tools and anything I can throw at it!

Crap, I was banking on nobody owning the pot! ;)

I just personally find there are better compressors for less money out there. I was going to buy that compressor actually!
