<html> <body> Gordon, I've read all the other responses to your post, so far, and agree. The only thing I will add, since you're dealing with all new parts, is to make sure that you have at least a "rough" hammerline set (off the rest felt) and at least "some" repetition lift. I'd also suggest setting the forward/back position of the jack first. Then, just watch for a little "wink" when you trip the jack tail out from under the knuckle. Hope this helps a little.
