I’m a bit confused as to how I use the barrel sleeve adapters for this kit. It seems that the barrel trimmer would be dulled instantly in the area that abuts the cutting surface of the barrel and the sleeve. Any input would be appreciated.

been many years since I turned a pen. So I can’t answer you question, but if you go to:

and ask, I bet you get an answer.

John: The barrel sleeve adapter slides over the 7mm shaft on the “stock” barrel trimmer. The adapter slides into the pen tube, keeping the trimmer square to the tube. There is no pressure put on the adapter by the cutters on the trimmer. I make my own adapters by buying 7mm tubes, gluing scrap blanks to them and turning them to fit into the various kit tubes. The cutters on the trimmer do not touch the adapters at all.

If I am missing your point, my apologies. Maybe with more info, I can help more.

John, after reading gwilki’s response I understand your question… You are saying the trimmer will dull where it trims the brass sleeve that is glued into the pen blank? If so the answer is yes it will dull eventually but if I remember correctly the blades on the trimmer are carbide, the sleeve is brass. Brass is softer and it will take a while to dull the cutter. I made a trimmer that I could attach coarse sand paper disc to (I cut the discs myself) glued the disc to my homemade trimmer and sanded the the blank/sleeve square. I could replace the sand paper disc when it got worn. That worked pretty well.
