New bottom end feels stiff

[BLACKBEARD]

I do believe that the crank is not seated in the bearings.
I will use the technique that Tobys two strokes referred to.
I'm hoping this is the solution (crank not seated). I am really getting frustrated and bothered by it. If it wasn't my first bottom end I'd be a little more at ease.
Thanks for ALL the support.

I would almost guarantee, almost guarantee, this is the problem, the crank is not seated and it has a load on the bearings. Any time you are going to tap on the crank you need to support the halves opposite the pin, it takes a pretty good hit to move it and without support you could cause a mis alignment. any misalignment will cause vibration, the amount of vibration is proportional to the mis alignment. I use the heat cold method and usually do not have any binding issues.

So I'm gonna take the crank out, put it in the freezer. At which point am I gonna hit it with the hammer? When both cases are on, or one at a time?
