I have the crank puller and luv it BUT how do you know that you are not pulling the 2 crank halves out farther than they should be, believe it or not the crank pin can flex allowing the the crank halves to be slightly pulled father apart than it should be.
Rebuilt cranks can be a .010 or more narrower or wider, when pressing crank halves together the pin will jump a few thousands or more at a time while being pressed together, not just a easy press fit where you can sneak up on a exact number.

That is the whole reason I run a semi-slip fit on 1 bearing so the crank can find it natural center no matter how wide or narrow the crank is.
Anyone looking for a great builder I highly recommend the following.
For CP products dealers I would recommend:
Arlan at LED(site sponsor), Pete Schemberger at Hybrid Engineering, Mat Shearer at Shearer Custom Pipes, Dennis Packard at Packard Racing, and Nate McCoy of McCoys Peformance.

Other great builders I also would recommend: Neil Prichard, Jerry Hall, Bubba Ramsey and James Dodge.

This is brilliant! This is why I can sit here for hours reading threads until my neck is sore. I really dig finding this stuff out. I may never personally apply some/most of it be it still helps
