914World.com _ 914World Garage _ SOT: New Tool

Posted by: McMark Aug 23 2011, 07:38 PM

Hey guys!

I've been a bit MIA over the last few months, but thankfully it's because I'm super busy. Still not caught up enough to spend much time chatting here, but I wanted to pop in and share my awesome new tool.

I've had a Harbor Freight blast cabinet for 7 or 8 years and it's never been particularly effective. One of the biggest problems was the gun, which is a fairly crappy design and which finally ate itself to the point where it stopped working. I searched for awhile for an alternative deign and surprisingly most every gun I found was essentially the same HF gun.

Eventually I found this gun in an obscure reference, and then finally found a place that sells it. It's actually pretty cheap (IMHO) @ ~$70 + nozzle. I had to do a little mix-n-match work to get the hoses hooked up, but it really wasn't hard. And the best part is that I stepped up to the Boron Carbide nozzle which last about 200x longer than the ceramic.

I got everything hooked up finally today and it was worth every single penny. I blasted a piece of tin which would usually take me 10m or so with the old gun and knocked it out in about 2 minutes. What a complete difference. Finally blasting in my cabinet works like I expect it to.

Good job. I know about that ceramic nozzle. Starts off with an orfice the size of a pencil lead and 2hr's later it's the size of a pencil. Question: where's the trigger. Foot pedal?? I'd really like to see that thing in action. Maybe you could do a quick YouTube video for us demo demons.

Sweet!

Been using a buddy sandblasting machine (More pricier brand)
and notice the drop in performance after a couple of hrs of use.

I thought it's me and he needs more air for the darn thing.
Thanks for taking the time to let us know!

What size did you get and what CFM r u running?

Yeah, I'd like to know which model gun and nozzle you purchased as well.

We have the HF 93608 cabinet at home. It's not the nice 'big' $1000. Industrial model, but I did buy the 'matching' reclaimer vacuum they sell for that 'big' cabinet.

I really miss the big compressor and giant blast cabinet I used to use at work

I got the 1/8" gun and the 1/4" nozzle. I have a huge screw type compressor, so I can't speculate on how a smaller compressor would handle it. According to their literature, the 1/8" needs 21 cfm at 80 PSI.

Here's the documentation...
