No , it is depends on the width of the drum and the gearing of the coiling gear . The easiest way to find out would be to contact the Secretary of the Steam Plough Club , who will point you in the right direction . Unfortunately the SPC has lost too many senior members recently , but he will point you in the right direction , to someone who knows the job .
The wrong size of rope would mean that the coiling gear would attempt to lap on too many or too few turns of rope . If you look at the muff , the bottom of the rope space , where the first lap goes on , you will see that it has a shallow spiral groove turned on it for the first lap to lay on . This will show you how many laps should be there . Divide the height of the rope space by this figure and you should get a rough idea . Correctly timing the coiling gear is another job which you will need to learn , but it will only work with the correct size of rope ; it is not adjustable , save for timing .
You do need to talk to someone who knows , and who has done the job , which is why you need to talk to the SPC . Details on their web site . Good luck , it is a nice job when you get it done .
