Last night I made special drills and mandrels for turning Pentel pencils like Don Ward talks about in a PDF. I'm having major issues though. I've gotten down the drilling, with the 1/4" body diameter, 5/32" tip opening, and 9/32" cap clearance, though I may switch that to 7mm.
The problem I keep having is slippage of the turning mandrels or fracturing of the back end when I turn down to final thickness. I am thinking about buying/making s special mandrel to fit my regular pen turning mandrel just for this purpose. How are you guys getting this to work out so well?
