PSI Woodworking PKM-BL Screw-On Pen Mandrel 1" x 8tpi

Q: Concerning the one listed as 5/8" for a Shopsmith. Could this be chucked into a three or four jaw lathe chuck?

You could, but you should not do that. It is designed to be screwed onto the same place your screw on your chuck.

Q: How does this mandrel fit to the tail stock? Will I need an adapter for my tailstock? (I only have a center point)

The mandrel has to be fitted to the headstock and not the tailstock. It fits perfectly to a 3/4" x 16 TPI headstock drive.

Q: Is there normally a little bit of slop in the brad point bit and 7mm brass tube that comes with the legacy kits?

The 7mm brass tube does fit in the blank loosely, but it seems to glue up okay. Don't forget to "scuff" up the tube prior to gluing with a light sanding. I only have the one bit and am just starting out myself, made 2 or 3 pens with no issues.

Q: Where can i find just the extended length 7mm brad point drill bits?

Search Amazon for Frisch 7 mm brad point drill bit.
