So I was originally thinking of building a drum sander got a free plan off of woodgears, but the motor seems to be my only problem with this idea. And this plan just keeps knawing away in my head(not that theres much to knaw on)so last night I’m in the shop and have this aha moment. I have a Gizzly lathe G0462 2horse variable speed motor 40” bed, 8” from bed to center of spur drive my big idea(and not original as it turns out) is mount the drum between centers, and build a removeable, adjustable table that afixes to the bed. My question is could this cause exessive wear, and possibly burn out the motor on my lathe? Because from my perspective thats the only downside. So let me have it go ahead squash my dream, rain on my parade etc…...

Higtron: I actually use an old craftsman lathe with a 1hp motor and it works wonderful. I’ll post some pics later. You have the right idea, I made my table with plywood and I glued a sand paper to another plywood piece in order to true the drum (that is if you are making the drum out of wood as well). In order not to force the motor, I make several passes and each pass I am able to sand up to 1/16 ( of course also depending on the grade of sanding paper you use) I use a 80 grid and it works for me. I’ve even used it to make my own veneer for a guitar that i’m working on. this is the guide i used to base myself when building mine http://www.woodturningonline.com/assets/turning_articles/lathe_mounted_drum_sander/lathe_mounted_drum_sander.html
I hope this helps!

Here is a concept from shipwright:

Here is another link:
http://www.shopsmith.com/academy/drumsand/
toward the bottom is what you are describing

This is a v-drum style sander. This is a commercial model but easy to build yourself.

I think a v-drum sander would be much easier to make than a thickness sander.
Good luck

Well I’ve made up my mind to proceed with this build, I will be advanceing the material through the drum sander manually for now if I get alot of burning I will rethink that at a later date. Now my idea for the drum is cut 5” circles and glue the discs together to form a 18” drum I’m wanting a hook and loop system my question is what is the best glue to use for this application, and say I use contact cement it seems like i would only get one take at being perfect, because any bubbles or voids would telegraph through to to the material being sanded. Also I already have lots of 3/4 ply scraps would this make for a stable drum, the reson I ask is most everyone who has built one and put it on the net uses MDF it seems to me plywood would also be stable, and as an added bonus moisture wouldn’t make it plump just wondering is it just the lesser price of MDF that makes it attractive for this app, or is MDF more stable.

I think the plywood will work well.

Well as it turns out I decided to go with the ply for the discs, drilled a 1/4” hole in each plywood square centered, drilled a 1/4” hole from the edge of my cross cut sled half the diamiter of my finished disc which is 2 3/4” turned a 14” dowel on my lathe and cut all my discs on the table saw it worked slick. I think I’m going to glue them up in batches since there are 19 of them tomorrow I’ll get me a length of 1/4” all thread for alighnment purposes. This is starting to get interesting.

well I was able to get my glue up the drum unit for my lathe powered thickness sander.
the pivot point is a 1/4” dowel on my crosscut sled it worked slick for cutting the discs, and finally the finished drum unit the big end is wher i’ll mount my face plate I used a 1/4” steel rod through the middle of all the discs fo alighnment purposes.

I’ve been working on my thickness sander again I’ve made a sturdy base for the ajustable table it’s easy as 6 wing nuts to mount onto the lathe.

alright I’ve finished my lathe powered thickness sander and I have a few photos and a video of it in opperation. the adjustable table is made of MDF 1 1/2” thick attached to the removable table with a piano hinge there is a hieghth adjusment bolt that lifts the table. The drum is hook and loop sand paper and the velcro mat and sand paper was my biggest investment. I trued the drum by glueing 4” belt sanding-belt to a 3/4” piece of particle board, on one end I had 50 grit and the other 80 grit it worked great. The dust collection is better than I hoped for, I can’t see any airbourn dust escapeing at all.
Here is the link for the video of the sander in action http://www.youtube.com/watch?v=kGVBo1aruZQ

Excellent! This saves me from buying yet another machine to clog my extremely limited work space. I can use one rail of my Record Lathe as the pivot arm. This will be really simple! Thanks for the efforts.

That is really nice and it works good too in the video. What grit paper do you use and what RPM is it running at?
I really like the dust collector because a sanding machine creates so much fine dust that get all over the place.

Now you have just placed another project in the job jar!!

Thanks for sharing!!!.............Jim

It turned out great. I may have to buy a lathe so I can build one.:)
