Woodworker's Tumbler ??

[RedVise]

So, this is a legit method of rounding corners  ?   Not my area of knowledge but kinda surprised me.

From the CL ad:
This is a machine patterned after those seen in several New England Professional woodworker's shops. The purpose is to round the corners and edges of wood parts by tumbling them in this device. In use, the inside of the tumbler is fitted with sandpaper, the wood parts inserted, the lid closed, and the parts tumbled.

The "box" was made by a woodworker and the frame, pulley design, and motor constructed in a professional machinist's shop. I am selling for a friend who had to stop substantial woodworking due to health. No reasonable offer refused.

never even heard of one of these machines but I guess once the sandpaper runs out it could be converted to drawing bingo numbers

A device to make crocket balls?

If I recall correctly, this was a suggestion in a Fine Woodworking article or tip, way back in the black and white days - late 70s, maybe.

I'm betting if they did a "How It's Made" segment on Scrabble tiles, we would see a similar device in action.

I have never known it to be used with wood. I know vibratory tumblers are common with metal.
