[TheForge] clock jack

[Wilson and Son]

I was cleaninig up the shop today and found a very good illustration of a
"Worm-Jack" in "Mechanick Exercises or the Doctrine of Handy-Works", By
Joseph Moxon.  Published in 1678.  It was reprinted on the cover of the NWBA
Resource Handbook printed in 1995 as a Supplement to The Hot Iron News.

If you want a copy of the picture I can scan it.
