Great info! I enjoy learning something new!
The rachet is a bit different on the two cylinders, one has a sharp "ramp" up to the tooth of the ratchet and the original has a longer more gentle slope. I was focuses on the tooth and how it engaged with the hand it never occurred to me to look there.
I'll take another goo look and see what I come up with.
I am in agreement that material shouldn't be taken off the ratchet.
I ordered two more hands from TOW last night so if I mess something up I have spares!
Thanks again Scorch very clear and appreciated sir.
