Sorry if this is resurrecting an older thread - Not a member - I was just looking for info on the 4" Dremel, as I compared it to my 1936, Companion (Craftsman) Tilt table 7" T-saw. - Made by Central Specialty Division, a division of King Seeley for Sears, I have been doing finger jointing on it and other fine work for several years.
The table is only about 11X14, and I just completed mounting it on an old school typing table (the type with retractable casters) to further reduce its footprint. The motor was mounted underneath, and uses a 4" door hinge for a gravity belt tension. The bearings (bronze), despite being 85 years old, are in perfect shape with no wobble or chatter.
While not common, they are worth watching for as I think they would be a great choice for the work y'all seem to do.
