I like the smaller diameter, longer handle of the micro and decided to see what I could do with the JW. Using delrin and aluminum I was able to shave 1.2 ounces off the weight of a Jim White head.
The handle is tapped and pinned so I don't think it's gonna move. I could see aluminum stripping if you were to get rough with it but it doesn't need to be tight at all to keep the head from moving.
That should work! I thought about that after I built a couple but the CF stretches even with a pin after awhile Delrin is much more solid. I was made all of mine with hand tools and a belt sander having a lathe is awesome.
