I have mandrel rods made for me, I think they are better. They last longer and does not warp as fast as others. I mostly make Sierra pens with a 27/64 tube. The tube fits my mandrel with out step bushings. The bushings are made to fit the mandrel and the mandrel will fit 4 blanks.
I first had one that held 3 blanks and used it for a year and got the new one that holds 4. I use the old one now to pre turn 3 blanks to almost finish size. By doing this I can pre turn them down very fast and never worry about warping my new mandrel. I can pre turn 100 blanks in just over 30 minutes and save me much time when I have an order. I can do as many 10 turnings a day and have 40 pens. 7mm pens I turn 4 blanks also with pre turned blanks. I'll try to post a photo by tomorrow.
