[PSUBS-MAILIST] q ball arm

Brian,
I do not have the original arm.  I only have the original seat for the q ball.

 Hank,
         Do you have the original cue
 ball / arm that was made for Gamma a long time ago?

 Alan,
 Thanks'
 So far this morning I have pressure tested the valve with
 the cue ball in it and it was fine.  I went to 500 psi,
 that is all the air I had on hand.  I have one end of
 the valve machined so it can bolt onto the original cover
 plate.  I should be working on my cart but this is more
 fun.  The cart is driving under its own power now.

  made a big discovery. A cue ball arm can be made very
 easily
  with a 1 1/4 ss ball valve and a 1 1/8 dia cue ball.  I
  removed the ss ball from the valve, just to check it out
 and
  found the ball is .004 in smaller than the cue ball.  I
 am
  going to assemble the valve with the cue ball in it and
  pressure test it.  If it works, I will machine the valve
  ends so the cue ball arm has maximum range of motion.

  When I removed the insert that carries the cue ball, from
  the hull, I found it wondewas damaged and causes the cue
  ball to drag causing damage to the ball.  Since I do not
  have the skills and equipment to machine that part with
 the
  radius in it, I will try the valve idea.
