![]() 226 forum posts 45 photos | 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?
