This is a question that puzzled for a while, but there is an easy answer.
I will supply the nut and the tool to fasten it.

I'm hoping to make a small batch by the end of May.

The cush nut has 4 castellation's, the clutch nut has 8. The internal thread sizes are totally different.

Mark I think it would be better to make tools that fit the standard nuts as per Robb's tools. Otherwise how would it be easy to remove the originals (Which might be in a perfectly serviceable condition) To then fit your special nuts? Ron

Blimey,

I should have gone to spec savers 😀 as they say in this part of the world! They're completely different 😳. I don't know how I missed that. I hope the rest of the strip doesn't exhibit the same lack of attention. I suppose I just saw 2 nuts with same castellated appearance; and 6 at that so not standard.

Thanks for comments and look out for the nuts and tools.

Cheers Neil
