[PSUBS-MAILIST] cue ball arm

[Alan James via Personal_Submersibles]

Looks like you have a lot of angle there Hank.Maybe you could use a spare pool ball & abrasive paste to get a perfect seat for it?You said that one pool ball cracked while drilling. I hope the pool ball can't push through if it breaks up.The size pool ball you are using is a children's size. 
I wonder if you went to an adult size ball whether it would be constructed of a better material?Alan

Alan,
Have a look at my cue ball arm assembly at Gamma restoration.  I repaired the original seat for the cue ball.  After Hugh said to forget about making a curved seat, I realized I could make my own seat on a 45 degree angle.  I made the second half of the assembly with a home made plastic seat machined from ABS.  I installed it in Gamma and it turns smooth as glass and has the original amount of range.  With home made plastic seats, it is a breeze to make this because the o-ring still does the sealing.  
Now I just need the plans and my new cue ball to finish the arm.  
Vance, 
I was thinking about mounting an air cylinder horizontal inside the sub to pull on the block and tackle cable.  The deeper I go the more air pressure I add, it will be like an adjustable spring.
Hank
