color sanding

Typically run it for 5 minutes, then stop and examine the work, take a sip of coffee, contemplate that state of the world, change the disc, etc. and the tank recharges and I start again.

Haha, thats pretty much my M.O. Dean, thanks for the kick in the pants. I should have it Friday.
Sometimes the coffee is replaced with wine ...but same dealio

On a more serious note, the DA produces a ton of dust. Protection is a must. The 3M pink filters that go on the respirator mask are awesome.
 
Thanks for the advice bud, I got a bunch of N95 filters for my half mask. You might have been the one who turned me on to the deal last year.

The older I get the more my OCD and old man aches and pains kick in. Often I only get 4-6 hours of work done in a 12-hour span... Not kidding.

Probably why I like stitch welding patch panels. Weld for 30 seconds, take a 10 minute break while it cools . . .

How come you don't use compressed air to cool off the stitch welds? I know on a structural weld it should cool naturally. I see all the high end fabricators cool the stitch welds with compressed air.

........or are you just joking around :)
 
Y'all ain't old lol. Bill Hines worked into his 90s I think. Last I read Gene Winfield is still working , I think he is in his 90s also. Have to say tho I can't do what I could 10-15 years ago.

Not joking. I let them cool to the touch naturally. It's how I was taught and part of a mindset of going slowly and carefully.
No one would pay me by the hour, but it's a hobby.

Thanks for the link Don. But It looks like it needs 17scfm and the best i got is 11.5 cfm at 90 psi. I don't think I'd be close even doing the calc's .
Looks like a heck of a deal though

I've got a couple ARO palm sanders that are rated 17-18 cfm@90psi. Like Don, I run them at about 50 psi and my compressor that delivers 12 cfm@90psi keeps up just fine even when running the sander continuously for 20 minutes or more.

The cfm rating on these sanders is based on feeding air at 90 psi, measured at the sander inlet, and letting the sander run with no load. Basically, it's a measure of how much air will blow thru the air motor when the only resistance is whatever is required to spin the motor with no load. That gives you a worst case number and actual use will give a smaller number due to lower speed of the motor when under load, or in the case where the user lowers the air pressure.

From things I've read in the past, the real difference in air use from a good sander to a $30 special shows up in actual use conditions where the cheap one may use as much as 50% more air than the good sander.
