How do you people sand the inside of your bowls? Do you just hold sandpaper in your hand and turn the lathe on or do you use some kind of foam holder on the end of a drill? Trying to hand sand a bowl and I can not get it line free.

What do you mean “You People”, just kidding. I do all of them from time to time, Mostly just holding the paper against the inside. I have 2 foam pads, 1 for my drill, 1 mounted through a bushing, with a handle on it. I have not had a lot of luck with the velcro deal though, it seems that they end up getting damaged somehow and not holding the loop very well. In any,case Keep the paper moving back and forth slowly, turn the lathe to under 800 rpms, and if you have a reversible lathe reverse the direction between grits. Occasionally I stop the lathe and hand sand vertically beween grits. Also with hand sanding, I will take a 1/4 sheet and fold in in thrids, it heep the paper under control, and easier to handle.
Good luck.

I don’t know how this might work for you, but I am a carver and I use a flex shaft grinder for much of my shaping. When I have to sand inside the bowl of a spoon that I have carved, I use a 1” automotive style abrasive disc holder/mandrel. This is mounted on my flexshaft and then used to sand the bowl of the spoon. I am able to get all grits up to 600. Since I grind the bowl using Kutzall style bits there is an awful lot of cleaning up to do.

There are a few different methods that can be used. Some of the more popular ones are:
  • Holding the paper in your hand (the one you mentioned
  • Using a hand held (powerless) sander
  • A drill powered sander

Each has a purpose, here is what I like to use. I will start off with a drill power sander (I use a Milwaukee angle drill) with the highest grit possible. I try to start with 220 grit but there are times I need to start lower (near the 100 range). I work my way up to 400 grit using the power drill method. From there I use hand held paper to finish to my desired grit. I have not used the handheld (powerless) sander but there has been some discussion here of it being used very successfully.

If you are going to reverse the lathe between grits and you are holding your work piece in a chuck there is one safety precaution to be aware of. Whenever I reverse the lathe I have 2 set screws in the side of the chuck that lock into the spindle when tightened down. You should never run a lathe in reverse without securing the chuck down first. I have seen a chuck fly off of a lathe this way when the screws were not locked in. To give you an idea of what could happen, I saw it on a metal lathe and the chuck was about 15 pounds. The operator started the lathe and bent down to put something away under the lathe and the chuck flew off and hit a cinderblock wall and broke through the first layer of the block.

The last part was off of your topic but I felt from a safety point it was important to mention.
