Interesting to me, love the old machinery. My oldest machine is a Craftsman drill press from 1951, made by King Seeley Corporation for Sears. Still works fine.
I have the table top model that’s on the right in the first pic. I have most of the attachments, the multi speed adapter, mortising attachment, shaper attachment, and planer. The ms adapter adds another pulley and belt and allows speeds up to around 17000 rpms.
I bought mine back around 1980, belonged to some young guy’s uncle. Everything came with it including the owners manual. I also bought from him the matching bandsaw, which I no longer have. Gave it to a cousin when I bought my Jet bandsaw. The drill press has essentially three sets of stepped pulleys with two belts connecting them.@firehawkmph
Pretty cool that you have all of those attachments. Curious - how did you come about all of it? Bought it all at one time? Piece by piece? Was it in the family?
I just noticed the catalog lists it as 11 speeds, 20 speeds with the MS adapter. I have a newer Craftsman floor model (~1975). They switched to a smaller belt with 8-step pulleys, for 8 speeds. I couldn't figure out how they got so many speeds out of yours with 4 step pulleys, so I had to find an owners manual online to see. I never would have thought to offset the pulleys to get more speeds. Makes me wonder if I could do that with mine even though it isn't mentioned in the manual.
