[PSUBS-MAILIST] machining q ball

[hank pronk via Personal_Submersibles]

Thanks guys
Emile,
I think the hard resin q ball is what Gamma had when it was built.
Vance,
That is great, I am thinking the q ball twisted in the jaws causing the drill to bind.  I can make a fixture to hold the ball tight without damaging it, while it is in the lathe.

 Hank,
 I've sent along some questions to the
 horse's mouth. Haven't heard from him in months, but
 I'm hoping he will get back to us shortly.

 help!
 I tried to machine a q ball today as an experiment before
 the proper one 
 arrives.  I put tape around it and put it in a 3 jaw chuck
 and while drilling 
 the hole through it cracked.  Do I need to make a fixture to
 hold the q ball 
 steady maybe?  I made a home made o-ring groove cutter and
 that worked perfect.  
 The q ball is very brittle, but machines very nice.  Any
 ideas would be 
 appreciated.
 Hank
