My next project that I want to make are end-grain cutting boards.
But I heard the horror stories of flattening them through the thickness planer.
I needed a drum sander and saw a lot of plans for home made ones.
I drew up some plans using Sketchup and started to build one.
Picked up all the hardware locally and I already had all the wood in my shop.
The drum is 25 pieces of 3/4” MDF on a 7/8” solid steel shaft.
The 1/4hp 1725rpm furnace motor is linked to the drum via a 1/2” power-link belt.
I even added a safety toggle switch to match the other tools in the shop.
The only thing missing is the sandpaper rolls.
I have looked and found that no one carries it in the Ottawa area.
I finally found some online from a store located around Niagara Falls.
I ordered a few rolls of different grits, but being this close to Christmas I fear that it will be in the new year before arriving at my place.
I can’t wait to make a few cutting boards, so I hope they arrive soon.
Thanks for looking.

I built one also. Love it. Mine has a 30” PVC drum. Most that I have seen (mine included) has the motor in the back and spins toward the front. Did I miss something or is your set up different?

Nice project build. I also was wondering about rotation. My other thought was about holding the work piece tight against the sanding drum?

Very nice and simple. I like the elegance of simpler solution.

On that subject, I noticed looking at a few people that have built these types of drum sanders that some like you have the drum below the table and some have them over the table. The over the table model require table height adjustment.

So my question is : functionally are there any differences between the two types? Are the results or capabilities different between the two?

@ Brian & Roger: I forgot to mention that I have a dust port in the back that my shopvac attaches to. Since the entire box is closed, the only place for air to go in is through the drum opening. It makes for a great downdraft table while sanding.

@BrianA: You are right, the drum spins toward the front, so you feed against the rotation. I could have put my motor in the back, but I wanted the box to sit flat against the wall when not in use and the motor would have been in the way.

@ SnowFrog: The two types of drum sanders that I am aware of is the Thickness sander and V-drum sander. The thickness sander has the drum above the moveable table. This would be the workhorse of drum sanders as you could take off a lot more material than the v-drum. Feeding the stock through is probably more difficult and usually need a type of treadmill belt or something for auto feeding like the planers. The v-drum is just barely touching the stock and is mostly meant for fine finishing. When the drum is stopped, the stock should not be touching the sandpaper. When the drum is spinning, the sandpaper pushes away from the velcro by a hair and sands the stock that way. If you want to take off more, then simply change the paper for a coarser grit. The top-dead-center of the drum and the table remain the same. You can also micro-adjust the table top via two screws on the front of the box to raise or lower the top, the hinge at the back stays the same.

I hope that I explained a few things for you.
Thanks everyone for the great ideas on this site, I could not have gone this far in my first year of woodworking without you.

I would like to see a photo looking down to see the mechanics of it.

Nice sander! What did you use for bearings?
It looks like the two pulleys are the same size. Then your drum is running 1725 RPM. How does that work out?
How do you hold the ends of paper on?
I’m trying to find out as much as I can before I design and build one, too

Thanks, Jim

Nice looking tool!

I have made about a dozen end grain boards and planed them all without any issues at all. I had heard horror stories too, but decided the time that it would save would be worth risking it in the long run.

Lots of glue, solid wood, lots of curing time and small bites with the planer!
