Hey I bought a set of Sterling Hopping Halves (yeah yeah Johnson I know) and after a couple of days practice the outermost [ of the English Penny is being clingy. Any advice on how to fix this so I can actually perform the trick.

Clingy? What exactly is it doing?

Mark.

It sounds like you may have dinged it out of round. Try placing the sun/moon assembly inside it and rolling in like a wheel across a smooth, hard surface. Put a little pressure on it and you might be able to bend it back enough to work.

To help find the flat spot, put the insert into the shell and look at it carefully with a magnifiying glass. You can usually push the flat spot back out with the edge of a smaller coin, like a quarter.
