back at it today!
it fits! really well. about 2 thou clearance and the bushings were concentric!
the big end. the mounting plate will be here one day
its not really a DIY project without a little blood letting... i didnt break the edge of the larger end and when it slid home, my thumb was in the way. Doh
then i dug this bad boy out of the pile. its the inside of a flange we jetted. 1.5" plate and about 12" diameter now. i will be making it all pretty as well as cutting a bore for a press fit on the shaft. i know the the chuck is over jawed. itll be ok for no more than it is.
