Fortunately, the spindle will pass the barrel nicely all the way. It looks like I'll have to make the spider bolts, so I may as well get a foot of 1/2" brass hex stock while I'm at it. Currently working on a piece of 3/4" steel, crooked as a dogs hind leg, need to fit the action on it between centers so I can face it square. But first I had to shim the tailstock for elevation, it was about 25 thou low. Then figure out a way to spin the bolt as its face is about 3.5 thou out of square. Thats hard on brass. Then measuring the tenon after getting it out, it doesn't match the drawing I have by as much as 37 thou in one measurement. And I need to make a headspace gauge as I've not managed to find one for the 6.5 C.M. Yet. Lots of work before I actually chuck up the barrel. And I found today, that the scroll in this 3 jaw chuck is an absolute piece of crap. So I am tightening it, measuring the runnout, loosening the mount bolts and tapping it gently to make it run true at the size its currently tightened on. This chuck, a Polish Bison that looks brand new, must be a very poor factory second to be that far off. I already cut the registration in the backplate down some so I could move it around.
