How to build a vertical round sander? Answered

Hello everyone. I recently started recycling empty bottle by cutting them and would like to build some sort of round sander that stands vertically on the ground or a table. I was thinking of maybe buying and old motor of some sort and attaching a piece of plywood maybe and just glue a sandpaper on it to sand of the edges off bottles to make drinking glasses or vases.Any advices would be appreciated or different ideas. Thank you.

I've heard that these are just way easier to buy than build.

But you can also use a drill press as a spindle sander.

Don't forget to wear a respirator when sanding glass!

In addition to head protection MENSA (Mouth,Eyes,Nose,Sound,Aegis) a vacuum to collect debris would make a lot of sense...

Very important safety note that. Yes glass should be either wet sanded (best) or with a proper respirator. Prolonged exposure causes Silicosis.

I mean, a spindle sander that oscillates all the time is a pretty difficult mechanism to build.

I drill press can be adjusted so you don't wear out the sand paper only in one spot.

But the simplest way is to attach a drum sander to a drill or dremel. I think...

Superb vid the motion is easily installed..
