I purchased an older Shopsmith that came with two SPTs (Special Power Tools) still in their original boxes. A jigsaw and a six-inch jointer. Both were made by Central Machinery in Taiwan to fit the Shopsmith. I had no interest in the jigsaw and sold it immediately.

The jointer box was beaten up pretty bad and showed signs of getting wet, but it was still covered with the thick oils that these tools are shipped from the factory.  New in the box but damaged. One end was sticking out and had some deep corrosion on it, and despite the oils, there was lots of surface rust.

I have been using steel wool and WD40 for many years to remove corrosion. In the past few years, I have switched to 3M Scotch-Brite pads. When removing rust from large flat surfaces such as this jointer, I use a Scotch-Brite pad attached to a 1/4-sheet sander I keep just for this purpose. The pad fits perfectly on the bottom of my sander. I don't use the sander for anything else.

As soon as the rust is removed, I cleaned up the WD40 with paper towels and mineral spirits. As soon as the mineral spirits has evaporated, I gave it a good waxing with Johnson's Paste Wax to prevent it from rusting.

A small amount of pitting and stains remained where the jointer was protruding from the damaged box. However, the pitting was so shallow it will not interfere with the operation of the jointer.

Now I had two Central Machinery Jointers. This one was newer than my original jointer, and I liked how the guard attached much better, so I sold the older jointer.

I do not own a Shopsmith jointer and cannot compare it to the Central Machinery jointer. It works well for me. It is a lot heavier, weighing in at around 100lbs. I would like to have a Shopsmith jointer, but until I can find a bargain on one or can't lift it, the Central Machinery jointer gets the job
