In the Canadian Woodworking magazine (Aug/Sep 08) it states this sander “is one of the few air sanders that can be operated on a portable air compressor” this is NOT true. This sander works less than one minute with a portable air compressor. I discovered later in the Woodcraft October Catalog that they note the sander requires a minimum of a 60 gallon capacity compressor or equiivalent to operate. I am sorry I bought this sander.

I really like this tool. It works very well for the purpose for which I bought it- working in tight places. I would further comment on a review I read BEFORE buying this tool. IT DOES REQUIRE A HIGH VOLUME OF AIR!! A “kiddie compressor” will not do! I have a 6 Hp/ 33 gallon compressor and it works OK for this tool. A larger system would be better. So, if you wish to use this tool with a small volume compressor, you may be dissapointed in the performance of this tool.

For the purpose that it is intended, it is a great little finishing sander. I own one with a 3″ head and got tired of changing pads so just bought another. I use it a lot for finish sanding on various large wood art pieces I create on a lathe. I have bought a couple of them and given them as gifts they work that well. This is a tool with a specific use and if used for other than its intended purpose, you will not be satisfied with the results or the tool.It does require a fairly high air volume for long term use so figure on that before you purchase it. Do not blame the sander if the air supply is inadequate.This is a RO sander designed for finish work. If you need to aggressively remove large or rough sanding areas, you have the wrong tool. You need an non RO sander to do this job. Do not blame the tool when you use it for a purpose it was not designed or intended for.

I found that it simply didn’t have enough oomph at all. I just wanted the thing for finer sanding on wood turnings (using grits above 400), but it will bog down under the slightest pressure, even with interface pads. Sent it back. And was disappointed because I really wanted to love this thing.I will say that it has low cfm/psi requirements so, while that is a plus, it’s probably also its downfall.

I am really not sure what the other reviewers are using for air to this sander, I am using a 40 gal craftsman compressor so nothing huge. I can not stop it!! It works absolutely perfect!! LOVE LOVE LOVE this tool!!!!FYI it is an orbital sander with a very small orbit 1/32″ I believe it said in the manual. This means it will just be vibrating under pressure, it is not designed to spin, that is what a die grinder is for. This tool has an orbital motion for sanding the pad will rotate slowly (spin) under working pressure.

A perfect tool for sanding bowls off the lathe. Works like a champ. It does suck quite a bit of air, so you’ll need a substantial compressor to run it. Ergonomincs are excellent, an extremely comfortable tool to use and manipulalte inside a bowl.

This is the second sander I purchased. The first one burned up in a fire. It works well for sanding the interior of bowls. It doesn’t leave scuff marks on he material. I operate it at 80 pounds of air. The sander keeps a constant speed.

maybe I have a bad one, but this unit stops with the slightest pressure. I can stop it with a fingertip!not at all what I expected, as I have a compressor that runs 5.9 cfm at 90 psi. I am attempting to use this with 220 grit and above, as a finish sander. My other air-operated sanders work far batter than this, and it’s definitely a bummer! Have contacted the manu, will update after working with grex.EDIT: original title was “really wanted to like it”, with 3 stars.after speaking with grex service, I learned that the velcro pad attachment is a free-spinning axis. The central drive shaft (which can be seen spinning away, above the pad, if triggered) does spin, and even if the pad stops spinning, the random orbit still works because the main shaft is spinning.I am glad I contacted grex, because what I was expecting was not what I experienced; I assumed it wasn’t working because of that expectation. I told the rep that this information was not in the manual. It would have been very helpful had it been, and I suggested editing it in in the future.I tested the unit today with the new knowledge, and I am very pleased with the tool. For one, it is much lighter that the 1/2″ electric drill I was using. That, plus the 105 deg. tilt, means less stress on the bod, which is huge when you’re playing all day. The sanding action is excellent, and the addition of an after-market medium-density innerface pad made it even better. the fact that it runs on 2.2 cfm means I can run it longer on my setup. luckily, the ergonomics make that far less of a chore than with electric tools.
