Sounds like you got too small a ball to be playin with the big boys out here. My hand hasnt slipped off mine ever.

I currently have the white shelby ****. I like it a lot. Doesn't get hot or anything. However, it has taken a couple of scratches that I don't like, so I'm considering going black.

I got the 8-ball machined this morning:



Here's a close-up of the insert...

Cliff out of curiosity, how did you secure the insert into the ball? Have a picture of the insert out of the ball? I see you threaded the insert and I'm assuming it is a slight press fit with glue and the threaded insert continues about an inch or more into the ball?

Machine the OD of the insert about .001-.002" larger than the ID of the ball, then throw the insert in the freezer before installing it, then let it sit til the insert is room temp. Should hold nicely

I did not take any photos, didn't occur to me--next time I make one I will.

The ball was drilled 5/8"Ø, 1.625" deep--the measured bore was 0.627" after drilling.

The insert was machined of 3/4"Ø 6061 aluminum, the shank is 0.626"Ø by 1.5" opened ended, threaded M12x1.5 a bit over 3/4" at the entry, the remainder of the insert bore was counter-bored (drilled) 31/64"Ø from the "back" end.

It was epoxied into the ball using a Permatex steel filled fast cure product, which IMHO will provide a more secure fit-up than would any attempt to use a press or chilled fitment due to the greatly dissimilar materials, and unknown properties of the ball.

There's plenty of surface area for the epoxy to bond (3.0in²), and steel filled epoxy sticks like "baby shìt to a blanket" on both materials.
