Your ball
valve is only made to turn in one plane and is not designed to swivel
around. The ball would only be able to go up and down and would not
articulate like the ball in the video. By the time you modifiy the ball
valve to do what you want it to do you will be putting more work into the whole
project than if you started from scratch.
I would be
willing to make this device for anyone who wants one for just the cost of
materials and a meger compensation for my time. I would like to test
one under pressure to see if would pass a functioning test.

Hi
Frank,
If you can also remove the nylon type seals used for
the large SS ball valve, perhaps they can be used in the final assembly as
your seals. I have a small SS ball valve at the bottom of my
sandblasting pot that is used to regulate the amount of sand coming out of the
pot and into the air stream. It takes several years of use before the
sand eats away at it enough to not seal anymore. Also I have to shut this
valve with sand are around it all the time, and it still seals properly with
those nylon type seals for a long time. Your arm ball will not likely ever
have any were near that much sand on it, so I think it will work well with the
nylon type seals.
Perhaps you can use
part of the SS valve body and machine it down to the design you want, then
weld it to a small thru hull SS plate that can be attached to a SS ring that
is welded into the hull. This way you can easily change the design in the
future if you feel the need or use the thru hull for some thing
else.
If your still concerned
about the sand issue, I still think rubber boots of the CV joint axles will do
the job nicely, and look good to boot. ;)'

Brent

Hi Guys. A stainless ball from a valve is easy to get, and can be
modified to work. Just weld over the slot where the handle goes, bush down the
hole, and it's all set. Plus, the valve body/seals can be used with a little
modification. The cue ball is great, if you can find a socket the fits it.
