Govenor drive belts

[Tony MartyrParticipant @tonymartyr14488]

On a beam engine I built some years ago the watts govenor was driven through a coiled spring steel 'belt' that was bought as a length, cut to suit and jioned by screwing the tapered end into the cut end. I have no idea where I got this material from – can someone point me in the right direction?

I am a bit concerned that such a drive using vee-groved pulleys might not be able to drive the Double tangye arrangement I have made and have seen in photos that a flat belt has been used – scarf-jointed and glued?

Stuarts do it in about 3mm dia and Mamod spring belts are about 1.5mm dia

It used to be a standard item used for film projectors in the 1960's but as they have gone so I suspect has the spring belting from that source.

Have nothing to suggest except ask if these are the same as, or similar to, the springs use in oil seals?

Mamod do closed and open ended steel spring belts.

Thanks to all – I have now found what I needed from Mamod spares
