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.</div><div id="yui_3_16_0_1_1474286523967_3255">Hank</div></div></body></html>
