While on the subject of Shopsmith accessories, I though it might be useful to show some of the items I’m using.

- the two items on the left are saw arbors. the left most one for saw blades with a 1 1/4” hole (the typical saw blades sold by Shopsmith). the other is for blades with a 5/8” hole.
- the third one from the left is a 5/8” arbor for a stacked dado set. Note that there is a groove through the threaded section. The washer (under the arbor) has a tang that fits into the groove as a safety feature to keep the nut from loosening.
- next is the lathe four prong drive center.
- next is the 1/2” arbor for shaper cutters (item #555117 I mentioned in an earlier post). It also has the safety groove and tanged washer.
- and last is the adapter for 1/2” router bits. Note there are three set screws, one to fasten it to the Shopsmith arbor and two to fasten the router bit into the adapter.

- the left most chuck is an independent 4-jaw chuck with a native female threat of 1” x 8 tpi for mounting to a lathe with that sized spindle. In front is an adapter from Penn State Industries that has a 5/8” smooth bore to 1” x 8 tpi threads for adapting this chuck to the Shopsmith spindle.
- the middle chuck is a older Nova that uses Tommy Bars for tightening the jaws. The native threads on the back of Nova chucks that use adapters is 1 1/2” x 8 tpi. So the chuck will fit lots of older metal lathes with similar threads on the spindle but you’d need a spacer on the metal lathe spindle between the lathe’s registration face and the rear of the chuck. In front are the two 5/8” smooth bore adapters. The “F” model is nearest the chuck; the other if the “S” model and preferred one.
- the right most chuck is a Nova G3, The insert there is the “D” model that fits lathes with 1” x 8 tpi spindles.
