Clever thinking. But I wonder if maybe too much demand is being put onto the lathe. Drum sanders usually have pretty hefty horsepower and the size shown would definately be a big drag on the lathe motor.
 
That's a good point. I wonder how that load would compare to say a 10" diameter 6" thick green bowl turning on there?

I would imagine if you ran the sander at the slowest, or 2nd slowest speed, that would provide plenty of torque to power through a light pass. I wouldn't want to try hogging off a 32nd of an inch with it, but it looks like it'd make a great way to gradually flatten out segments for small bowls and such.

I would have to agree with Frank.

The 1014vs pictured only has a 1/2hp motor and the Jet 10-20 has a 1hp motor. Another thing about this is that it seems to take a lot of setup and there are other home made units that would not have the motor limitation. I think shopnotes or woodsmith had a real good unit featured earlier this year.
 
How much strain could it be? How would a 10" diameter 6" thick green bowl blank compare? I know that once you got a bowl blank spinning, you get a flywheel effect, so that might be a considerable factor. Then again, modifying something to do tricks it wasn't designed to do always comes with a certain risk.

I hadn't even noticed it was the VS. From what i've seen of that model, i'm kinda glad I have the primitive pulley style system. The torque loss at low speeds would drive me crazy. I think the plain 1014 would stand a better chance over the 1014VS model.
 
Interesting idea and lots of good comments. I can see the potential concern over power, and yet I can also see where this is good for someone with tight space concerns or limited need for make heavy passes with a drum sander or doing small pieces and has patience. For a pen turner and needing to flatten smaller pieces this saves the concern over planers and small pieces and even with a fair amount of material to remove 20-30 small passes with this is going to take off a considerable amount of material.

If you have a tablesay in the shop and want something a bit beefier though Mudder is correct in that Shop Notes had a setup earlier this year I think may have been 8 months ago (if anyone really wants to know I can look it up in a few days) where they built a unit to sit on top of the table saw and drove the drum from the tablesaw motor thus giving you a sizeable motor and torque capability to remove lots of material from large pieces. Why they kept the size of their design so narrow I do not understand as I would build it much wider than they did if I were going to the effort of making one.

SN #86 was the drum sander issue. http://www.shopnotes.com/main/sn86-toc.html

I think they went that narrow for the same reasons we are discussing about stress on the various parts. In the shopnotes case, i think it was more concern for keeping the whole drum from flexing under so much strain. Then again, that's just a guess. It's got support on both sides so maybe it could be a bit longer, i dunno :)
 
I made a disk sander out of an old facplate and piece of plywood that I use frequently, but had not though about making a drum sander also. I have an ocsillating drum/belt sander already so I don't really need one, but neat idea.
 
I have mine about 1/2 way done. I just need to build the drum. I really don't think there will be a lot of issue with power as this is a sander, not a planer....[;)] I willpost poics later when I finish it.
