However, both sections work OK electrically.

I would rather you don't ask for it until you have had a go at fixing the one in your set first. In any case if can get the original working it will probably be more reliable as your set has not seen the damp that my spare pot has seen.

Hi Andy,

Spent this eve looking at this pot. As you can see the outer shaft has snapped along where the C clip would attach to. (As mentioned it was bent!) The surface area looks quite small to attempt to epoxy it - I won’t be able to re attach the C clip! Both Read good though.

I could attempt gluing the shaft but concerned it will have a weak point with the C clip tight around it.

What are your thoughts?

Would you have a shaft from a dud pot which could be sacrificed to repair this one!
