Versatile 5/8" Molder / Dado Arbor
Here's a great all-around arbor for use with dado blades or the Shopsmith Molder Head. Includes a 1-7/8" long 5/8" diameter threaded shaft, two steel washers, a 3/4" thick spacer, a locking tongue-washer and a hex nut. Fits MARK 7 and all other MARK V models. Having extras allows you to have a variety of tools ready to go to work on a moment's notice... without bothersome change-over.
Not for use with the Shopsmith 10-ER, Mark 2 or old Mark VII.
