I use a robo sander for my edges after the cut out. Start with 60 grit...then 80 to 120. I had to make a few extra wheels for the finer grits. I made them slightly smaller for each grit. I have a dewalt RO. I'll go to 220 with that....and she's all hand sanding from there. abralon works great for contours ,cut aways.I know what your sayin.I tried finer grits on the orbital,abralon. wet the wood down and said @#$%^&*! ...nice fine orbital swirls....no good! So I think though it's not my favorite thing is... hand sanding has it's place. Have to say a oscilating spindle sander seems interesting...been eyeing one up through grizzly.Think that would be the cats #$$ for your edges. hmmm my dream list..jointer,thickness planer,better table saw,bandsaw,drum sander, oscilating edge sander,lathe,dust extraction....damn santa left me coal this year so hopefully next year ...after I take out a 2nd mortgage to finance the equipment I'd like to have. For now it's what I got...and I'll get by. Main thing is I'm enjoying it. Think the big equipment takes the fun out of it unless your mass production.
