Sandblast Question
Hi all,
I wanted to restore some parts from my Corvette. So, instead of bringing the parts to the local sandblast shops, I decided to buy myself a Cabinet Sandblaster (floor model). It works good but it is very dusty.
Has anyone here ever vented a sandblaster outside the garage? If Yes, how did you manage to do so. I don't want to pay $300-$400 for a dust separator since the sandblaster itself only cost $180.
Let me know if you ran into this issue before.
Thanks,
Oakley_77

I vented mine to the outside of the house using a small squirrel cage blower out of an old Xerox maxchine. There was a "hole in the wall" store in Manhattan that sold just used fans. $15. It has a 4" dryer duct size outlet, so I used dryer vent hose etc. The fan is mounted in the top of the box so that only the light dust gets sucked up. I also put a piece of screen over the fan input to stop the larger sand granules from flying out.
My box is home made... the top location was an option in my case.

I run a shop vac as well. Put a filter on the inside of the cabinet over the vent hole and attach the hose externally.
Make sure you have a vent to allow some air into the cabinet. I sealed my cabinet so well initially that the shop vac pulled the gloves right into the cabinet. A small vent hole allowed the negative pressure to dissipate. Works great in my garage without any dust. Just be prepared to change the shop vac filter often.

I used my shop vac initially as well... and it worked fine... but random bits of sand eventually found their way into the top motor bearing and the vac burned up. That prompted me to get the squirrel cage blower.

I also use my shop vac and it works fine but I do have a question - Where do you guys stick the vac hose?
My cabinet is just one of the cheapies and it has an outlet on the side away from the door and another in the rear up top. I just shove the vac hose in the side hole as it is slightly larger then the hose. I assumed the rear one may be an air inlet? It has a "cover" inside the cabinet that is about an inch out from the back 6 in wide and extends about 12 in down. I never take the plug out as enough extra air gets around the hose.
