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?

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?
