Dave Barnett here in Hutto, Texas.
Although I've been aware of ShopSmith for years I am just now a first time owner having picked up a Mk5 (ser# 328507, 1956 year of manufacture) at an estate sale last week for a "pig in a poke" price. On my initial removal of the headstock covers it is fairly apparent that the Speedial had been rotated without the motor running at one time or another in the past as the motor belt was riding on the shaft of the adjustable sheaves.... I do not know how long the unit sat idle before I bought it but I think it was at least ten years. I was fairly sure when I hand rotated the attached table saw blade that the motor was probably going to need replacement as well, which has been confirmed. Judging from the condition of the belts I believe they have been changed at least once. Everything inside the covers was clean and still well lubed. The tubular ways had some very minor pitting in the hard chrome but the power head still travels quite smoothly. I paid $300.00 for the Mk5 which included the jig saw, planer, and shaper attachments as well as chuck(s), lathe tools, and assorted shaper heads so I feel I can probably spend a few bucks more and still have a fine tool and a good value.
My initial questions are- 1. Was any serious damage done when the Speedial was rotated without the motor running and, if so, is it user fixable (I'm good with tools and follow directions/drawings well)? My initial examination did not reveal anything that looked catastrophic and the Speedial mechanism still moves the adjustable sheaves. 2. When replacing the motor should I stay with the original 3/4hp motor or bump up to the 1.5hp motor used in later models? I'm going to assume that motors are available from SS.
I'll also be looking around for a good magnifying glass to be able to read the impossibly fine print in the owner's manual diagrams (I have all the original paperwork that came with the tool; I believe I am only the second owner).
Looking forward to a part of the ShopSmith community!
