Hello, I was wondering how people make bouncy ball counterweights?
Such as what bit size to use, thank you!
There isn’t really a set bit size, but I suggest just using what ever seems wide enough to thread the string through, but not so wide that it takes away weight from the ball.
And all i do is drill a hole?
Thanks!
yep 
get a rubber ball then drill a hole in it then put your string in it
