I bought a used Shopsmith Mark V about four years ago. It came with a whole bunch of extras, but until recently I had never tried out what looked like an air compressor and spray attachment. I admit it looked a bit scary to me :) But when I cleaned out my shop today (a floor remodel is coming soon), I figured blowing compressed air around with one fan on the south window and another on the north window would be great to get get rid of all the dust along the walls (I have a shelving system salvaged from a Borders close-out).

So I got out the old compressor. It connects to the lower shaft of the motor, not to the upper one like most other accessories. I did not even know that I could use the other shaft… I cleaned the shaft, connected everything, put some safety glasses and ear plugs on, and started the Shopsmith at low speed. It worked perfectly. A smooth rattling sound and that old old hose was still air tight and blew out air.

Although the previous owner had all kinds of documentation for the Shopsmith, there was nothing on this item. It looks like it’s from another company, and converted to fit the Shopsmith. There are pulleys, but they are not used as far as I can see. There is nothing like it in the current Shopsmith catalog.

Does anybody have one, or know anything else about it?

I just found a blog by the “shop-smith-toolhunter” that shows two different air compressors that were once available for the Shopsmith:

It turns out that mine is the older version. A lot of info is in the newspaper ad posted. So the pulleys were actually used to connect to the older Shopsmith 10ER.

I wonder if I can spray shellac with this… might be worth a try.

It is amazing what tools we find at times, glad to hear it still functions and that you may have a use for it

Yes, it is really great to have a “free” air compressor. At least for cleaning up the shop it has been working very nicely.

I haven’t tried the spaying attachment yet, but I am going to once I have my shop floor remodeled. I use a lot of shellac, and it would be great to be able to spray it on parts that are hard to reach.

I have a compressor like that also. but the legs do not mount in my Mark V. They are to close together I figured it is meant for the 10er. Turn it by hand and it feels like it should work. Can always use up a salvaged motor and make things work.
