Sand Blasting cabinet rental for small parts

[Vikingblu]

Ok, sometimes I'm a little slow to catch on, but I started to count everything I need to paint (and sand) and I ran out of fingers, toes, and well...it was more than 21. So, I can see it would be pretty convenient to be able to blast the small stuff at home and there's a lot of small stuff. Big stuff...I'll either do it manually, or take it somewhere. So I've been doing a lot of reading about blasting (can you smell smoke yet?), but it's difficult to tell from equipent specs what you can really get. Bottom line, my compressor says it's 7.2 scfm @40, and 5.8 @90 psi. (27 gal) Is that enough air to run a small cabinet like the harbor freight model for $119 at home? or 50lb pressure pot hooked to it? or will it be so slow it's just not worth it unless I have more compressed air?

It really depends on what the intent or purpose of your blasting is.
Rusty wheels take an extremly high quantity of air.
Small bits, like an alterator bracket not so much.
Are you removing deep seeded rust?
Are you dusting parts so paint will adhere?

I prefer to degrease and wire wheel parts, so as not to contaminate the blast cabinet.
To test your air quantity, you could hook up an air tool such as a 5 inch grinder or an impact gun and pull the trigger. If it winds down within 10 or 15 seconds, blasting will be aggravating. Waiting for air to build up every 30 seconds is not fun.
