ok I feel stupid 
I was looking at sandblasters this morning. *THEY* said not to use less than 50-60CFM and 80-90PSI.
disregard. Good buy Jim!

Ben I bought my DA at the farm store. It's a cheap chinese knock off, $40.00, but it ought to last a while no more than I'll use it.
You can sandblast with the smaller compressors if you'll stop and let them catch up. Some of the cabinet blasters recommend about 20 cfm to work good. One thing you can do is use a small diameter tip on the gun. The bigger the hole the more air you'll use. 1/8" is about as small as you can get and after use they will enlarge over time just from the abrasive eroding the hole.

DA's use a lot of air, having 60 cfm would be nice but 10-15 cfm at 90 psi would be better than 6 cfm

Jim, I really like your air compressor. I really like the stand that you have it on. What a space saver. That is really a good idea having the air compressor up high and above most of the dust for the intake of the comp. You might want to make a noise barrier around it using a thick isolation barrier.

Thanks Larry. I already have shelves under the stand and have been sorting my tool steel and keeping it on them. I will keep the noise barrier in mind. It is on the end of the shop where it's away from the machines and where I spend much of the time. Maybe one of those accoustic walls would do nicely though if I am not happy with it. I'm anxious to get it running to see.

No it's a single phase Scott. My phase converter was going to be maxed out if I bought a 3 phase, although they run cheaper. For that reason I got this one. It puts out as much air as the 10 horse 3 phase and was really cheaper for me to use in the long run. Monday I'll go hunt down some more #6 wire and finish running the power to it.

sweet compressor jim.
D/A sanders are great,but something to watch out for is the little counterweight.you can get your fingers hit by it and it HURTS(ask me how I know)almost broke my finger.after the tenth time,I chucked it into the spare tool drawer and got one with a guard over the counterweight.

 Been there, done that, several times...yesterday 
Jim...Quincy compressors are perfect for your business. We've got some around the shops and I'd swear they are from the 70's and still going strong. Good preventative maintenance and they will run forever.

I can imagine that would hurt. Thanks for the heads up.

Jody I'm hoping this will be the last compressor I ever need to buy. It's been running in the shop all week and doing great.

It looks like my grill is in pretty good shape. Maybe a bit of surface rust but none that can't be dealt with fairly easy. I am wondering about something. The area where the grill bolts to the frame is closed in and the only way to get that apart is to grind the welds off. I really don't see any need to do that but at the same time that area won't get any paint in it when it comes time to paint. I am thinking of slathering the inside with POR-15 to take care of any potential rust. Anybody have a better idea? Thanks.
