Thanks for the great how-to. I have quite a bit of experience on the lathe, I have been turning for almost ten years, I had just never thought of combining my leatherwork with the lathe...
a couple of questions:
Do you use contact cement for all of the gluing? (you mention it on the tube insertion, but not on the "board" assembly.)
Have you tried this with a 7mm tube? the pen in your photos looks to be a bit larger tube. The only kits I have on hand are some Woodcraft Europeans.
Lastly, is your finish a1:1 mix of lacquer and Neatsfoot?
Thanks again for the write-up, it helps alot.
