Somebody edumacate me on cranks and trigger wheels please

You will have to double check the stainless not triggering the hall effect sensor you have. The ones I've used in dairy automation have triggered on stainless.

Thanks. I was definitely going to check - will make something sketchy up using a bench grinder i think. Now where are my safety glasses...

I am planning on having the bolt I want to trigger several mm higher than the others anyway (so theoretically ok with all steel). Using stainless is belts and braces.

Any chance this is of use:
