## Questions & Answers

**Q: Concerning the one listed as 5/8" for a Shopsmith. Could this be chucked into a three or four jaw lathe chuck?**
A: 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)**
A: 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?**
A: 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?**
A: Search Amazon for Frisch 7 mm brad point drill bit.
