Hi all.

Can someone send me the link again for the dry divers cue ball arm thing people are talking about.  I must have missed the email with the link on so i havent actually seen it.

Thanks
James

Jay,
           Do you know how they made the seal on that cue ball?  You're
right about machining stainless, but not impossible.

  The cue ball was handy and readily adoptable for the first manipulator.
Cue balls were originally made from ivory, then nitro cellulose (the first
plastic but a touchy explosive they found out), and then plastic.  A ball
valve will have a limited range of motion due to its standoff from the hull
and will be difficult to work with due to the large diameter hole through
the middle.  Stainless steel would be great for the ball but may be
difficult to machine for the home machinist.

  I want one too !    I don't get the cue ball part,  wouldn't you have to
have a hole thru the cue ball?   What are cue balls made of ?  ceramic?
What about using a ball valve or simply machine a large stainless sphere and
put a hole thru it.
