I thought I would pass this polisher/sander idea along. It is in the magazine, Woodsmith, in volume 38, edition 224, for 2016, so that would have been the last magazine back from the one out now. The one that this is in, has a cherry office desk on the front cover. It can be found on the net, in PDF. This station is constructed from plywood and MDF, and is similar to the polishing machine I designed and built awhile back. It would be easy to convert to polishing wheels, or use a drum sander on. They're using a 1/2 HP motor the same as I did, with a pulley reduction.

The two round spindle extensions, consist of 4 round pieces of 3-3/4" dia. x 3/4" thick, MDF, each, that are glued, stacked, and fastened together, using 3, 1/4"-20 x 5-1/2" long carriage bolts, that go through the housing sides, with nuts on the end to pull them together. The end discs have large 1-3/4" center holes, for ball bearings to be seated into them, on either side. The 3 discs behind the ends are drilled out to clear the thru-shaft, with 1" dia. center holes.
Each frame side consists of two pieces of 3/4" plywood glued and screwed together. One could easily use MDF for that, too. Overall, from the end face of the spindle extension, to the inside of the side frame wall, is 4-1/2". The two side frames are held 5" apart with plywood spacers. Overall, from the face of one spindle to the next, is 14". They are using a 5/8" dia. x 18" keyed shaft. However, one can cut flats on the shaft, for set screws, and it will work fine, plus save a good bit of money. I would use a 22" shaft, having 4" of stick out on either side, if it were me.
The round pulley guard on the front, is a section of white PVC pipe.
