Whether hand sanding or power sanding on the lathe few points need to consider. Buy quality sandpaper. Only reason we sand is remove tool marks and even out the surface for finish.
You can do as much damage with sandpaper as with your turning tools. Sandpaper not a substitute for good turning techniques.
Keep lathe speed at lowest RPM’s while sanding, use light pressure, and clean surface before moving to higher grit paper. High RPM’s generate heat and destroys sandpaper. Pressing hard and high RPM’s only burnish wood surfaces and leaves sanding scratches.
Base your sanding sequence on wood species and finishing product. I do not always start sanding with 80 grit sandpaper. Worn out sandpaper is not your next higher grit, switch out worn out paper with fresh. Do not move to higher grit until have removed scratches from previous grit. I have had to improve my lighting because shop light was not enough for my old eyes to see damage done with sandpaper.
This video shows great technique and gives great pointers on power sanding.
I use 2” backup & interface pads with 2 3/8” disk from Vince, and angle electric drill and air drill for disk sanding. Do not think will buy larger disk, because still end up doing some sanding by hand anyway.
