Drum/ Thickness Sander

When all is said and done, the abrasive belts are required. They have to be costed, obtained and glued.

Not cheap.  :bang:

Hi Simon, this is an interesting project you've started and I'll be watching how it develops as you progress.

I just did a bit of googling for info and found this link to various drum sanders. The Jet sander seems to use a conveyer belt system similar to your design and if you look at the specs you can gather some useful info about drum size and feeds etc......Link: http://www.rockler.com/jet-benchtop-sander-1hp

And the provision to 'crown' the rollers to keep the belt 'on track'?

Let's say that I am farting about with my bandsaw- and trying to replace a broken twin clarinet stand for my wife's A and Bflat clarinets.

Said I'd been there :poke:

I've been a little apprehensive about the idea but gave it a go today. I'd done some tests on spare disks of MDF and didn't have any luck getting the diluted glue to penetrate to any depth, even trying to add a bit of vacuum with a vacuum cleaner. It might be a case of just getting it fairly close to final dimension and soaking it for a while to get just the surface hard. I'm still also unsure how the MDF will react to being soaked in water, as it'll probably take months to dry out fully (especially if the glue seals it), so the whole thing might warp after a while.

But with no other options i'm aware of, im still trying it. If it doesn't work out i'll just replace the MDF with plywood like I mentioned earlier.

NormanV:
The trouble with PVA is that it dries rubbery and will clog up the abrasive paper that you use to smooth the roller. Varnish would do a better job of hardening the MDF roller in preparation for sanding.
