I am going to build a homemade thickness sander like Shipwright has done.

I have read a lot of the posted projects and online plans. People have made the drum from PVC, MDF, plywood, and hardwood. I do not like the idea of hardwood due to potential issues with dimensions changing with humidity. I have some minor concerns with PVC pipe due to potential heat buildup

An alternative is 4” aluminum pipe with .250” wall and price would be about $50. My concern with this is how round it would be and difficulty truing it. With other materials, you can use a flat sand paper surface.

For those who have made one, which material would you recommend? Have you had any problems with the material you used?

Also, stockroom supply shows drum diameter of 2” and 4”. My current thinking is 4”.

I built a lathe powered thickness sander I used plywood for the main deck that keyed onto the lathe bed and was held on with bolts the sanding bed was 3/4” MDF 2 pieces laminated together with a strip of maple glued on for mounting the piano hinge for the adjustable table for the sanding drum I made of laminated plywood disks I used hook and loop for sandpaper attachment http://lumberjocks.com/projects/52836 I originally wanted a stand alone unit but couldn’t find a used motor and didn’t want to spend the bucks for new motor so this was my solution. Good luck with yours mine works great I got my original plans for free a woodgears.ca it was for a free standing unit

My question is…What did you make the drum out of and have you had any problems with the wood or MDF in the drum swelling?

I used plywood for the drum disks glued them all together to make a drum and I had no swelling problems

this is a picture of the drum after I un-clamped it after glue up. Once I built the adjustable table I glued a belt from a belt sander to a flat piece of particle board I had laying around 36 grit on on edge 80 grit on the opposite edge and trued the drum with the adjustable table.
