I have been making lathe turned pens for several years and have always wanted to engrave them. Laser engraving is way beyond my budget. However, the Baker Rotary jig may do the trick, if it can be modified to accommodate something less than 1/2" dia, using a mandrel to support it. Has anyone else done this, or does anyone have any ideas how to do it? I am not intimately familiar with rotary jigs, but they appear to be a possibility.
