Stoker,
The bore is consistent from end to end. I measure .238" and .239" on the narrow side of my mistake.
I've had the wind cut out of my sail. I need to walk away for today.
Meanwhile, I replaced the bearings in an electric motor I'm overhauling for my son's table saw.
You do have another option to consider here Jeff, and it is the one I'd likely give the most consideration too, were it me.
PM Research does sell individual parts for their kits, so there is that option for you to think on.
Meanwhile .... walking away can be a very good thing sometimes ...... but you'll be back, I've no doubt what-so-ever!!!
