    I have an idea, still in its very early stages, of building a drum sander.

    I looked on eBay for conveyor belts and they're all big money.

    I just saw a running machine on Facebook tonight...

    They must be ten a penny a few months after all those new years resolutions have finally been laid to rest. And, I assume, they would have all the speed control gear built in and salvageable. And a decent motor?

    I'm honestly not sure as I've ever even touched one of them, so I have little idea really - has anyone here had one apart, and are there good, useful, salvageable bits, or is it all sealed unit proprietary stuff?

    I don't even really know the scale of them, but they look about right for the conveyor of a drum sander build?

    Good motors like 2 hp surface size L130, W43cm.
    How big are you looking at

    Small really. My planer is 10" - it would be nice to double that, bit 430mm width of belt would be fine.

    I've not used a drum sander, but the designs I see pertain to being able to do double the width of the drum by hanging the job out the side, and doing it in two passes. I'm slightly dubious of this, but if it was all solid enough, I guess that could work.

    But, yeah, I'm not talking an industrial machine.

    Ahh, no, it's not that sort of machine that I'm after at all.

    I'll find a photo in a bit, but it's one of those woodworking ones, that are like a thicknesser, but, instead of planer knives, it's a cylindrical sander.

    So the work passes under the spinning cylinder, and it makes it a uniform thickness (and smooth)

    I know what you mean. Just cant think of the name. Some have the belt grit pointing down, the workpiece is slid under on a moving table/conveyor, and pressure is applied to the sanding belt.

    I think they're called something else again!

    (A yard I used to go to had one...I don't even really know why they're advantageous, as you don't get the thicknessing quality from them?)

    Yeah, there are a few different type.

    I dont think they are in tended for thicknessing, more finishing

    Cheapest on ebay for a used small jet is about £500 or so, it seems.

    But, i figure i can spend 3 years, and £800 building one...

    Joking apart, they are a conveyor belt (speed adjustable) and a motor connected to a cylinder that you can raise and lower.

    I mean, i know ill probably spend out way more than expected on parts, and way longer in time, but it cant be that hard, can it?
