[PSUBS-MAILIST] Q - ball arm

[hank pronk via Personal_Submersibles]

Brian,Actually, you use an actual 2 1\8 dia billiard ball.  Then drill a hole through it and machine that hole to 5\8 with an 0-ring groove for the 5\8 hollow shaft that slides through the ball.  Then you make up ends for the 5\8 hollow shaft with o-rings to seal the inside shaft.  You end up with two shafts that slide in and out and rotate.Hank

 Thanks Hank, when I get a little further along I would be interested in that.  I was thinking that a cue ball type ball could be machined with some shaft on each side which might make for a more ridged part. Brian

Brian,Remember I have a Q ball arm socket sitting on my shelf if you need a picture or anything.  I actually made a Q ball arm socket one time from a ss ball valve, the billiard ball fit it perfectly.  I also was going to experiment with making a metal socket without the hassle of machining the curvature to fit the ball.  I thought about making the socket with a square seat and pour in high compression casting resin-using the ball for the mould.  So essentially your making a ball valve plastic seat.  Just  some thoughts.Hank_______________________________________________Personal_Submersibles mailing listPersonal_Submersibles at psubs.orghttp://www.psubs.org/mailman/listinfo.cgi/personal_submersibles
