A thought occurred to me recently when trying to compare the V-drum type sanders to the homemade thickness sanders: why can’t I make a tool that is both? And here are some sketchup models showing what’s in my head:

Basically, there are two tables that use the sanding drum, one on top of the other. For those of you with dust collection setups (not me), I added a dust shroud in the middle that might collect some of the dust.

What do you guys think? Am I crazy? I won’t be able to build this any time soon, but it should be fairly cheap. All the frame members are 2×4s.

Interesting thought. I am also in the process of building a drum sander. I don’t understand what the benefit of the v drum is. I wish I had some experience to offer some insight. One thing I might do is increase the length of the outfeed table.

The top section, the V-Drum sander (anyone know why it’s called “V”?) is similar to an abrasive jointer, whereas the bottom section is just like an abrasive planer.

Are the infeed and outfeed tables offset as they would be on a jointer?

PaulfromVictor, not that I know of. As I understand, the amount of wood taken off is even small than in a jointer. I’m not sure how they get away without offsetting the tables, but search lumberjocks for “sanding flee” or “v-drum sander” to see more about them.

You sir get +1 smartypants point for this idea :D

-- - Jei, Rockford IL - When in doubt, spray it with WD-40 and wrap it with duct tape. The details will attend to themselves.

this is nice ,
the biggest problem i think ,
is raising and lowering the ’ planer ’ table .

on the outfeed side ,
have some holes for a pipe at stagered heights ,
and a notch in the framed table to ride and stop on the pipe .
the front can be raised or lowered by wedge or screw mechanism .

I’d be a little nervous about on the planer part that it would grab the piece and shoot it out the other side…

only problem i can think of is the dust collection… its not just for show on drum sanders the dust collection helps to stop the paper from clogging up which can prevent burns and all that nasty stuff…. you’ve defidently got a winner there are far as the idea goes but i would say see what you can do about some dust collection.

My understanding of the sand flea type v drum sander is that the abrasive is attached to the drum with hook and loop velcro which allows the abrasive to raise up and give some flexibility contacting the workpiece. The drum and abrasive actually sits lower than the work surface untill the centrifical force of the spinning drum makes the abrasive raise up to contact the work piece. A thickness sander being a more rigid/solid sanding surface is not likely to work well with abrasive loosely fixed to the drum like that.

Don’t mean to rain on your parade.

What type of sandpaper will you use? PSA or H&L? The reason I ask is the V drum sander will only work with H&L. If you are planning on using H&L for the thickness sander too there shouldn’t be any problem with your plan. I don’t have a thickness sander so I’m not sure if H&L can be used with it.

Dan, I guess the worst thing I would have to do is have two different drums that could be interchanged. I’ll have to think about that some more. Thanks for the constructive criticism. That’s one reason I put it up here: so I could see what holes people shoot in it and how to mitigate those problems. Thanks!
