I had built myself a Vdrum sander but also wanted a thickness sander but didn’t have room for two machines. Then I saw someone on LJ’s built a dual thickness/vdrum sander and that was it. I had to make one.
I started with making the 20” drum from 4” ABS pipe and 3/4” shaft. Made jig to true-up the drum with the router. It worked perfectly.
I purchased a used manual treadmill for the feed mechanism. Ended up making new frame for it.
The motor is a 3450 rpm 1.5hp from a dust collector I had given to me free. Reduced speed down to 1725 rpm by using a 2” and 4” pulley’s.
Lift mechanism is simple threaded rod. The rear of feed mechanism has holes in frame that allows me to adjust thickness of sanding if required. To feed pieces through just turn the handle. I find that I can feed it through and then turn handle backwards and forwards several times without adjusting height.
Dust collection is easily moved from top to just sit on conveyor for use as vdrum sander. I made a fence when in vdrum mode so I can also use it as edge sander or even like a jointer.
Whole unit was put on old vdrum stand.
All in all this sander works fantastic and is accurate within 0.05mm on entire width of 20” drum. Thanks to all LJ’s who posted similar projects for me to get ideas.
Here is a quick video of it. https://www.youtube.com/watch?v=ik2jwVqYHzg
