Could anyone suggest a supplier of flat belting made to measure suitable for my three inch scale showman's engine please?

We had a conversation on this last year, but can't find it.

You have a choice of leather or canvas depending on pre war or post war.

A google search for either leather or canvas belting will find it

Thanks to all who replied. I already had a belt but it was too tight and risked cream crackering the dynamo bearings. I eventually found the maker of the original belt and have ordered from him.

If it only ‘risked’ damaging the bearings, wouldn’t it have been possible to slightly elongate the holding down bolt holes?

After removing the fiddly connector box screws on the fron of the dynamo, hanging upside down under the canonpy to disconnect the concealed voltage regulator, removing the countless tiny nuts and bolts from the canopy supports, then removing all but inaccessible dynamo hold down nuts and then removing the dynamo base from the smoke box extension, hand filing the slots (I have no milling machine) the replacing all the above and finally re-touching the paintwork inevitably chipped during removal.

I reckon a new belt is a bargainsmiley
