In addition to the crank, you want to look at the infeed roller. If it is rubber and based on the SN it was originally, it will be worn and likely will not feed stock reliably. There is an upgraded metal roller from Shopsmith that will add more cost (about $60), but improve function.ChrisNeilan wrote:There is a stand alone power planer available in my area for $450.

Make sure it runs, and visually verify that the feed roller mechanism spins and is speed adjustable.
Check the chain tension on the bottom of it that raises the table via that missing crank. Grasping it firmly, you should not be able to move it anymore than 1/2" If it was run that way, it is possible that cranking it up and down allowed the chain to jump a tooth on one or more of the elevator bolts rendering it unlevel. All can be fixed. All effect price you should pay.

is a tuneup video that you would benefit viewing either way as it will help you assess condition, and will help you service it should you negotiate a price you can live with.
I love mine. It is rock solid.

Besides I have five 10ERs with speed changers and a complete adapter kit.
