Hi James
I have purchased the K350 plans and plan to start building as soon as 
possible.I am pressently researching lathes
I hope someone could give advice on swing over bed size and size between 
centres that i would need for building
the K350.Thanks for all your advice.
ps the dry divers sub manipulator ball valve idea could be worth considering 
but being a comercial diver for
many years i have seen ball valves fail countless times due to something as 
small as a grain of sand getting stuck in the seals .As for the mechanics of 
the manipulator i think the same concept as a device used to lift fish out 
of the water by there lower jaw after being  cauht by a fisherman could 
work.
All the best from South Africa

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Cue balls were originally made from ivory, then nitro cellulose (the first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.
