I was talking
to my 78 year old German friend about making a ball and socket. His
is was a tool and die man who lived through the war as a young kid, he
eventurally came over here and worked for Hughes Aircraft making all kinds of
top secret missle guidence parts. I may try and make the ball and socket
out of aluminum first. I'm not sure whether or not aluminum would work for
this application, it would depend on the grade I suppose.
Here is a
link to the tool needed for the lathe set up:

Brian,
You made me think of
a knife making video I was recently watching. Where they made knives out of
large steel ball bearings, because of there high carbon content. You
might be able to acquire one of these large steel chromed bearings, and drill
through it and weld in a SS tube. Then rechrome or nickel plate that assembly.
Then to deal with the sand scratching or getting in the seal issue Frank
brought up. I was thinking that a second free flooded sell like a rubber boot
off a CV drive axle might do the trick.
Regards,
Brent

of "cue ball" arm

I wonder what other materials that cue
ball, (or sphere ) could be made out of? What about brass, or a type of
plastic?, stainless would be bullet proof, but more dificult to
machine. Also one could use steel with a nichol
coating. anodised aluminum ?

Hi Guys. Here's the link Jon put up for the Mantaray submarine with the
grabber arm for those that missed it. It's a youtube video and fun to watch.
Note that it's in two parts. Thanks again Jon.
