Hi Pete,
Oops... You forgot to mention that you're changing from 5/16 inch diameter to
1/4 inch diameter rope.
Forget about splicing the ropes, you should purchase new pulleys that are
properly sized for your new 1/4 inch rope and replace them too. Otherwise your
new rope will wear out prematurely from being flattened out by a shieve that is
too wide to properly support the circumference of the rope.
