How do you figure out the no. of drive links? A piece of string around the edge then divide the length?
I still gotta get a chain made for my bow bar. The easiest way is to take it to a shop with the saw you're gonna use it on and they can make one up for you on the spot. Then you can just count the links on the one that's made up and order new ones yourself. I had my bow bar (which was an NOS one for an old Homelite) modified to fit my 041AV Super.
