So how do you make that work with one solenoid?

I don’t

… I saw no reference to there being only one solenoid

Hello. I wish to make some levers to be operated by electro-magnets.

… note the plurals.

Edit: __ but, if you were so inclined, I suppose it could be done with ‘flat’ gearing anyway … no need for a concentric stack.

It was me that mentioned co-axial ratchet wheels, and in the same sentence referred to 'the pawl'. You wouldn't have more than one solenoid for one pawl?

Sorry, Duncan … we are obviously at cross-purposes

I thought you were questioning my [immediately preceding] remark to James.

I was once told , that to ensure that the armature releases from the Electromagnet, the magnetic circuit should not be complete, having a very thin shim of copper or brass between the armature and "lever"

Possibly Aluminium foil would serve the purpose.

What do you think Robert?
