Disk Sander Adjusting Table and Fence

by John

In a previous post I showed an early stage of this component. Yesterday I completed it.

The table now has a central slot, and a series of M2.5mm threaded holes at 10mm spacing. The protractor fence slide also has some 2.5mm holes, allowing the slide to be fixed anywhere along the slot. The motor is reversable, so either end of the table can be used. The protractor fence has holes at 5 degree intervals, and some felt pen marks at 30,45,60 and 90 degrees. I will ask Stuart T to laser some more permanent markings. The brass knob fits neatly into the holes. In this position the sander machines a neat square end in the wood.
here table is accurately held at 45 degrees and the fence is also at 45 degrees, allowing a compound cut.
Sanding a compound cut. All of the angles are accurate to a fraction of one degree. Pretty nice hey?

It occurs to me that the holes in the fence could be used to rotate a piece of wood to make a disk, or an arc from about 5mm diameter up to 150mm dia. The disk could have sloping sides, in the form of a truncated cone. Hmmm….. all sorts of possibilities when you make your own machines.

So this machine is almost finished. I just need an attachment for a vacuum hose, and/or a dust collection container.
