Appears to be out of print at this time...

I got my chicoines book on Ebay and theres alot of info on what size repo arbour pins are what can work Ect.
Its a great book for anyone who pulls everything apart or likes to.

For sure!

The upper hole is the actual pin hole.

The lower hole is the drilled out centering hole for the lathe. The the blind pin and the arbour pin were absolutely invisible until I broke them free. Hence why I thought the arbour pin was threaded into a blind hole as well. Your blind pin *May* not be in the same place.

Also, the peanut gallery that is my extended family produced lots of useful advice after I screwed up, as is usually the case. If you're having trouble seeing the pins, use a wire brush to clean away any corrosion or dirt, wipe clean, and brush an acid on. It will expose the transitions between the frame and pin. I tried it on a test piece and it worked.... too bad no one told me about it before

Wally,

THANKS for posting it. I spent some time studying mine and pin is totally invisible due to the aging + corrosion of the metal. Even under microscope I wasn't able to tell separation lines. Now we all know where to look. Appreciated!
