For penturning i have some different mandrells. For closed end and open ends. A standard bar in a MK2 collet and a nut on the other end is one of them.
I use it with the bushings that i bought for every kit.
Today i was busy with some penblanks and i put some bushings on the mandrell but i noticed there was wiggleroom between the bar and the bushings.
The battery on my calipers died so i don't have the exact play. The standard calipers showed 0.4 mm play. Is that normal?
Sanding a alsmost finished blank shows the ends have a little difference in wall thickness. The tube is out of round, What to do?
