Drum Sander Burning

Like any new tool, through use you discover its idiocyncracies, and the drum sander is proving no different.  Some of the positive points include its ability to sand and thickness particularly short items, something an actual planer/thicknesser cannot manage without undue amounts of snipe, or worse, actually lifting the board into the cutter head where it is shattered by the knives.  This is even more true for particularly thin boards, such as veneers.  The drum sander on the other hand is perfect for both these.

On the other hand, the cutting mechanism is still sandpaper, and as I discovered is still susceptable to issues such as clogging and overheating (and in this case, both).

It is just a matter of learning what can, and cannot be done, and the techniques and methods to avoid the problems.  In this case, I probably had too slow a feed speed, so the sandpaper couldn’t clear all the sawdust, and importantly the workpiece started heating and overheating, to the point that the clogged sandpaper couldn’t cut, and instead burnt as can be seen here.

I’m certainly not saying the machine is at fault – this is very much operator error.  The capabilites of the machine open up all sorts of possibilities, particularly of short, thin, or tricky grained timbers.
