I have a hundred or so small parts (1 1/2 x 1 1/2″ up to 3 x 3″) to “finish sand.” The best it seems is to use a finishing sander (e.g. my PC 505) turned upside down or some other oscillating sander that way, then hand- hold the part against the vibrating surface. The problem is the heat generated by the sander now rises up, heats up the platen, and the sanding pad separates from the platen. Hook & loop no help because the velcro separates the same way from the metal platen, with the abrasive sheet still attached. . I have tried a variety of adhesives (e.g. 3M 77, 3M Fast-Tack Trim Adhesive, etc) but they all fail. A belt or RO sander “throws” the small part, making it hard hold. I am experienced building large pieces of furniture, but this small part stuff is getting me down.
How do you work with small parts?
Thanks.

I find this type of stationary disk sander very versatile. The table gives good support so it's also safe to work with small pieces.
don't cut early
Man, your making that too much work. Sand those in long sticks and then cut them down. Otherwise if you have already cut the parts. I'd do one of two things, use a sanding block to hit them with. I use to make wooden angles and with the irregular shapes the cutting long and sanding was not an option. If you get into a groove it does not take as long as you think. Also don't sand to a 1000 grit :) do a 120 and 180 and she should be good to go, a 220 on end-grain if thats the case. Other option is a vise to hold them and then hit em with a sander.
Even if you sand, which you should, before cutting the parts; it's still a good idea to finish sand all surfaces after cutting. Bones is right about you making this too much work, though. Glue the sandpaper to a flat surface and move your small parts over the sandpaper. It's very quick to sand this way and working through a few grits is as easy as it is quick. You'll also keep the surfaces flat, avoiding the surface rounding machine sanding tends to introduce.

thanks for the suggestions. I guess I'm too much of a machine guy, so I overlooked the hand options.
EagleAmerica & Rockler offer "small parts holders." Believe it or not, that's what it's called.
