A drum sander with two different grit sanding sleeves is something I have wanted for a while. I suppose I could of bought one but where is the fun in that. The first picture represents my first attempt. I prefer to use a term Norm uses for his first attempt "prototype".
In the prototype I first turned the cylinder, then drilled the center, next cut the wedge. This caused three problems. First the center hole drifted off center. Second the cylinder was now out of round by the distance of the saw kerf. Third when the sanding sleeves were installed and tightened it was next to impossible to get them apart. The prototype also exposed a inherent flaw with wedge design. As the wedges are drawn together it distorts the round shape. I ignored this and keeping the tolerances close the distortion is negligible.

On my second attempt I cut the wedge while the stock was square. Much safer than cutting the wedge in round stock. Next I drilled the center hole. The next machine operation was to drill spring pockets in the center. The pocket drilling operation made the back hold down to creep. I solved this by putting the light hold down in the track next to the wedge. Compression springs help separate the wedges when removing the sanding sleeves.

The next problem was how to mount the stock with a 3/8 hole in the center. My solution was to grind a point on some thread rod, remove the pointy thingy from the tail stock and mount the other end in the drill chuck. By using the lathe chisel sharping jig and the disk sander I was amazed at the accuracy of the center point. To keep the wedges in place during the turning operation I screwed the wedges together making sure both ends of the screw were below the outside diameter of the cylinder. Looks like I run out of picture space. Post to continue.

Drum Sander post continued
Next I waxed the wedge surfaces (JPW to the rescue) and assembled. If I ever make another one I will use a 1/2 in bolt and cut the head off the bolt on the chuck mount side instead of 3/8 threaded stock.

Looks like someone has been having fun in the shop!
I really enjoy when members share projects and add some build details. While I might or might not ever make at particular project I can and do "steal" ideas for other uses.
A job well done, thank you.

ps
Here is something I did some years back and it is still in use today. It makes use of the shopsmith 6" drum sander and shows the option of multi-grit, plus.

Speaking of idea stealing
Before posting I searched "drum sanders" I didn't want to step all over some other post. During the search I ran across your post. I see some form of your design in my future. I should be able to extend the thread rod point and use the tail stock to stabilize the drum during sanding operations and build a table similar to your design. I prefer to call it adapting not stealing.reible wrote: ps

Nice and clever off label use of the sharpening jig. I like it.
