We are restoring a 1988 3-horse slant load trailer and we purchased this sander hoping it would be easy on my wife's wrist who has carpal tunnel in her right hand. (She is doing the work on her own) She was using a palm sander along with a regular sander (both electric) and every night was in pain. This Orbit Air Sander is great. She uses it daily and hasn't complained once about numb fingers or hand. We highly recommend this product to everyone needing a decent sander.

This is a great little sander! It uses solid (no holes) 5" PSA disks that are available from Amazon in a variety of grits. I use it with my Porter Cable 3hp side stack compressor. It uses a fair amount of air at higher settings, so I do let the compressor catch up while wiping off dust.

It is recommended that several drops of oil be added to the machine each day. I found that it tends to shed a little oil right after it is lubed, so I run it wide open for about 15 seconds in a cardboard box to shed the excess oil. This keeps the oil from getting on your work and all over the shop.

It does have a speed control valve which is very sensitive. The lever only travels about 1/2" from low to high. You can also control speed to some extent with the pressure limiting valve on your compressor. Maximum operating pressure is 90 PSI. I have used this for wood and metal projects with great success. On wood with coarser grits, you should start at a lower speed to avoid overcutting.

You will also need a 1/4" male coupler plug to fit this to an air hose. I use "M-type" Milton connectors on my system.

This runs much smoother than the old electric pad sander I already had. I will grab this one first from now on!

Being female using this sander is very easy to use in the line of work that I do. It is so lite compare to the trojan D A's,that I've used my sander most of a 10 hour workday and I'm not as muscle-strained as with the heavier sander. I've had my old Sioux going on 5 years and plan to purchase another one! I highly recommend this product.

I am rank amateur, but this is a great sander...
It's very light so if you're working drywall you don't get tired as fast, i'm really pathetic at drywall so i sand alot...

Of course you need compressed air, but then EVERYBODY should own an air compressor...

The stick-on sanding pad are a great help..

I bought this after a great deal of research, alot of people really like this sander...

This and a decent belt sander and you're covered....
