HF 110lb Blaster questions

What is the CFM rating @90 PSI of your compressor?

PSI and gallon capacity mean nothing when considering blasting.

After about 30 seconds, all your gallons of air will be gone, and you will be relying on the througput of the pistons, or the CFM.

If it is less than 10-15 CFM, buy a new compressor before you buy a sandblaster.

At 10-15 it will still be a struggle.

My main compressor is 32 CFM and is fine. My other shop compressor is 8.4 and will not work for anything larger than a tennis ball sized object.

I've been working on a 73 RR hood, and have been through six bags of playground sand, and I'm only about 1/2 way done. (see last sentence)

The sand cuts just as good for me as coal slag or garnet, which cost 5 or 10 times more.

I reclaim about 40% of the sand, too.

Yes, I know...don't use sand.

...and wear a helmet...and a seatbelt...

I do wear a 3m respirator and blasting hood along with tyvek coveralls and welding gloves.

I also recommend using a DA for the easy to get at parts and the blaster for the difficult areas. That will save time, money, and exposure to blast media.
