While I was waiting for answers, I simply took a 'large plastic wall anchor, heated it with a Milwaukee gun and stuck the appropriate size nut inside, and let it cool off. Then I used it as the socket.

Long term, I think I will trake a piece of plastick stick, will heat the same nut, and jam it in the end of it, and then will use that. May be drill a hole across and insert a metak rod to make it easier to rotate.


What I found, I was able top use my metal socket, but then I had to rotater and retract to see the real effect.
The rotate - retract was only needed at the high end of scale adjustment and IF adjustmentl at the low end of scale the effect did not change whether I kept the socket in or removed it.

It is doable, just not convenient.
