Hi all
I have a yen to (someday) build a bookbinding press. One of the
mainstays of this is of course the press screw which does the
pressing. I'm wondering where to get a large example of one of these
from. I've seen vice screws on (eg.) the Axminster website, and I'm
sure these could be turned to this purpose. They are spec'd at around
28mm diameter. If I were to decide I needed something a bit larger
than this, any idea where to find one?

(Any links to plans or ideas for building such a beast also gratefully
received)
