Retractable pen made from 30-06 bullet casings

I think this is a cool project and the video may teach you some new machining or fabrication methods even if you don’t want to make a retractable pen out of a couple of empty 30-06 bullet casings.

The pen looks like it’s pretty easy to make.  The hardest part might be

Video: Making a tailstock dial indicator stop

This short video shows you how to make a dial indicator stop for a Grizzly G0602 lathe that can be easily adapted to other lathes.  The stop is used with a magnetically mounted dial indicator to very accurately measure depth when drilling or boring.

You may find this video worth watching even
