I’m looking to buy a 5” random orbital air sander. I have used them in the past, and I know the basics – you need a good, large air compressor with a supply of dry air. I know they use a lot of CFM. I’ve got both. What I DON’T know is what size of “orbit pattern” to get. I’ve got my choices narrowed down to Dynabrade, Mirka and 3M. I’ve used the 3M before, and was happy with it, as well as a Porter Cable. Both were good, but didn’t last terribly long. (about a year)
So, the three brands above all list the orbit size ranging from 3/32” to 3/8”.... What should I pick? I do mostly cabinets, and have been getting into furniture more. I’d use this for the last grits – 120 and mostly 220 grit. I’ve got the Porter Cable “grinder” (right angle) style sander that I use for any aggressive sanding/leveling of joints, so I won’t really be doing any heavy sanding with the air sander.
Any imput is appreciated. Thanks!
Oh, and finally, I hate sanding. So I want to spend the least time sanding, and get the nicest swirl-free glass smooth finish as fast as possible! Just in case that has a difference on anyone’s input!
