Time Standard: 3.85 min/round (3 min 51 seconds per round)
Scrape off any wax from the barrel round.
With conveyor belt & drums running, hold the round in one hand, and adjust the conveyor height until the round is just touching the roller bar.
The staves of the round should be running with the conveyor.
As the round is sanded, be watching both the amp meter and the speed of conveyor belt.
If amp meter starts to spike, lower the height.
If belt slows down, lower the height.

Pull round out and feed through again, raising the bed 1/2 -- 1 full rotation.
Repeat this process until the surface is mostly consistent.
For individual spots that are refusing to be sanded, you can leave them and sand with random orbital or surface conditioner. Don't waste time trying to feed through drum sander.
Use a low grit at first to remove the marks, and then a higher grit to smooth it out.

Make sure the dust collector port for the belt sander is open.
Do NOT use the belt sander for any rounds that are falling apart. The belt sander will rip it apart immediately.

Never let your hands get close to moving belt. Readjust hands frequently by resting the round on the metal table of the belt sander.
Take a piece of 150 grit sandpaper, pinch the newly sanded edge with it, and quickly sand the edges. This will smooth out any remaining sharpness or roughness.
