Removing twists from chain
I have found that it is important to remove the rotational twists in the weight chain on a 30-hour grandfather clock. If you don't, it can derail the weight pully, when winding up, so to speak.
Having set the chain over the strike and time pulleys, and the centre loop being around the weight pulley, which will be in the fully wound position. The two outside down runs can hang free, the chain being parted at the bottom, but this will not always get rid of any twist. Finger-and-thumbing down the chain drives you mad after about four goes.
Answer: simply insert matches across the chain links about every 150mm as you go. Like sailing ship spars, the chain is the mast and with all match heads facing you rejoin the chain.
