I can't either. Nor can I see the ones in 109.FYI, I can't see the images in post #108.
I made an expanding mandrel. It's a piece of tubing with a slit about 2" long. There is a tapered brass plug that spreads the end. It grips very tightly and I use it a lot for tapping. Quick and easy to take on and off.How did you attach the hand wheel to the spindle?
