A far better solution is to buy #8 solid bare copper from your local big

Pretty simple. lay out 200-250 ft of it, tie one end to an immovable object
(tree, utility pole) the other end to a trailer hitch on your towing
vehicle, and very slowly pull while an assistant observes. When it breaks,
coil it up and repeat. With assistants, I've done this for four 1,000 ft
spools, each of which yields about 1,200 ft of #9.:)
Do you have a trick to make sure it breaks at one end or the other instead
of the middle?
No, but it's always broken very close to one end or the other.
