REQ Help locating rollers

How about using the passive rollers with a driven belt laid over them?

Try a search for "gravity roller". What you are looking for is actually a powered gravity roller conveyor. Try this as one of many links.

================================================ Are you looking to build a power feed like

If you're hoping to put powered rollers in the tables, keep in mind that there will not be enough friction between the roller and the bottom of the wood to add any significant push to the work. Powered rollers need to squeeze the wood between themselves and the machine.

That would work but I'd steel need to locate a rolle that I can drive, which brings me back to the original problem I think :)

No, I;'m looking to add power feed to a 25" wide drum sander, where the rollers will be an integral part of the machine. The rollers you pointed out come at 4" max, way too small.

Yes I'm aware of that. I plan to mount the rollers above the wood, and they will be spring loaded to keep pressure on the stock. That and the right choice of roller covering will move it right along. Thanks for your input :)

Where are you located? Ive a bunch of urethane covered aluminum rollers, nice and tacky, with keyed ends. You make yur own shafting, and keyways, mount on pillow blocks (of which I have all sizes)

The methodology of the left has always been:

1. Lie
2. Repeat the lie as many times as possible
3. Have as many people repeat the lie as often as possible
4. Eventually, the uninformed believe the lie
5. The lie will then be made into some form oflaw
6. Then everyone must conform to the lie

I'd probably think about scrounging the drive roller from an old treadmill and reworking the drive train somehow to slow the speed down.

Hmm. We had something like that at the night job I used to work at, it was a feed module that mounted to an arm, and was used to pass parts through a shaper. The rollers were about 5 inches in diameter, and about the same wide.

But they also had a variety of other planers, and they had integral feed rollers - I would suggest you contact a woodworking tool manufacturer or specifically somebody who makes planers.

The small one we had was made in germany.

--Look for a kewl gadget called an Omni Wheel.

Oh - that's a good idea. Just use the treadmill drive train - it uses a variable speed DC motor (and controller). If the speed range needs to be adjusted, the treadmills have a ribbed belt in the drive and the pulley sizes could be changed. IIRC, Chipmaker has a bunch of these. Maybe he could be talked out of a few, for the right price.

BTW, why do you need more than one driven roller? It seems to me that only the roller nearest the sanding belt would need to be powered. Isn't that the way the power feed on a thickness planer works? Well, one on the infeed and one on the outfeed.
