Drum Sander

This is a drum sander I finished up a couple of months ago. I would never have attempted this without the inspiration that I found on LJ’s. See my favorites to see all that inspired thiis. Stewart’s site has links for various plans. I also liked Autumn’s. Blake’s machine inspired the clear dustcover. That was a great call. It allows you to see all the action, and troubleshoot if needed.

I made a few changes of my own. Most obviously, the bed is granite. This was a piece that was cutout from my kitchen counters to intall the sink. It has been sitting in my garage for nine years waiting for a project. I mounted the granite to a piece of plywood, enclosed it with a wood frame, and filled the missing corners with stones and fiberglass resin. The bed is 20.5” wide.

All of the steel rods on this are 3/4”. The backside of the bed rests on a steel rod. I made additional holes in the frame so that I can move the rod down to accommodate thicker items if needed. I am not sure if I will ever lower the table, but just put it there as an option. I like the idea of being able to make a sled to pass items through. In theory, the lower holes will still keep the table parallel to the drum, but that has yet to be determined.

The motor is 2hp, spins at 3450 rpm. I used a 2:1 pulley ratio to cut the drum speed in half.

The drum is 5” diameter and wrapped in velcro to attach the felt backed sandpaper.

Already I am hooked on this machine. I don’t know how I got by without it.

Really nicely done !

1700 drum speed is still pretty fast, do you get any burn marks. manual feed? I’m thinking about building one any other reccommendations. Oh yeah where did you pick up the drum

Good job. Really clean build. That always seems to help keep things true.

I know you will love using it. So much these can do.

Looks really nice, you did a great job. I’m planing one, I was going to try a treadmill as the table, it has a veriable speed motor, just need a larger motor for the drum, still in the idea stages.

Great Job! Love the use of the granite! 1700 rpms vrs 1350 I read most sanders spin at should be a problem right? Love it, I plan an buying the Kit from Stock Room Supply as I don’t have enough time for everything I need to get done… Very impressive work my fellow LJ’er A++++++++++++++

Hey, that looks really good. The idea of using granite for the table is a very good idea.
Have you checked how flat is the table? I once got a large slab of granite to use as my table
(in the drum sander) but it had a deep about 0.01”. The stone supplier said it is within their
tolerances and I just returned it.

Thank you for the compliments.

Mreza. The table is dead flat, and being granite, I expect it to stay that way. It is a great worksurface; hard, flat, and almost unscratchable.

Ken and Dock, 1700 RPMs on a 5” diameter drum seemed to be the sweetspot based upon the machines I was looking at (see my favorites). I have not had any issues at all with burning.

The only thing I have found to be careful of is to keep the wood moving through. If you stop it will leave a small mark similar to what snipe would look like. Don’t let that scare you, it is not hard to feed at all. If I do a large piece, I have my wife help with the last few passes. She pulls a bit as the piece exits, just to make sure it doesn’t stop.

The use of granite was a nice touch.

Thanks Autumn.

A drum sander is not something you would think of as dangerous, is it? I guess you get something spinning that fast, with a powerful motor behind it, and anything can happen. My concern is the belt. Mine is exposed, and I can visualize myself sticking my hand in it. I am going to put some kind of shield around the belt at it’s danger spots. Nothing pretty.

Nice work Paul, it looks like a good one. I also very much enjoy building my own equipment when I can. You really put some nice detail into that project.

Excellent job it looks great. Question: What prevents the boards from shooting out the end?
