I got the two on eBay for $20 and they are finished beautifully. They are Chrome plated, the rim is machined smooth, and there is a spot to drill for a spinner handle. I am really impressed with them and one reason is they have about a 1/4" hole so they are open for any finish bore size. I happen to need about .375" give or take a few thou. The bad thing is , I went back to get two more and they are all gone. Another seller has them for $15 each , so I ordered another because I need three total. I went to Enco as suggested in an above post, but the smallest bore is 3/8" and I'm not sure how accurate it is. I need a good fit on my shafts so I'm going with the $15 one. (I should have ordered the doubles when I could).Where did you find them Mark?
Those look really nice. Are they good and solid?
I need to get a couple of them for another project also.
