Figured I'de let you guys feel the pain of the time difference for a little while. You don't know how annoying it is to get telemarketers calling you from the east coast at 3 a.m. out here.
Anyway, Here's an easy fix for the Jr. Gent/Barron Pen. I had to try it before posting it. Heres what you do.
For the larger ID tube: Take your barrel trimmer and........... slide the center bushing from a European style kit over the shaft (without the tenon guide). I put a little ca (I MEAN A LITTLE) on the shaft to keep the bushing in place. This bushing is just a hair under the ID of the larger tube and does a great job of cleaning out the tube and keeping the cutters perpendicular to the end of the blank.
For the smaller tube: Same thing except use the smallest bushing from the Euro Kit after you've hit it with a skew a couple of times. Or take a new one and sand it a few seconds with 200 grit sandpaper while it's on the late. When new, it is slightly larger than the ID of the smaller tube of the Jr. Gent. After you sand it, it will fit perfect. Put it on your barrel trimmer and go for it. The barrels are the same size for the Jr Gent/Barron so you can use this with either.
I'll work on the full sized Gent tonight but you have the general gist of it. I used to turn my own bushings but it is amazing how hard it is to get them little buggers exact.
