    I'm crapping mi'sen abart goin t'big.

    So took the bar out and measured it with a bore gauge, 41.70. The finish is excellent, so hoping to get it to size without needing a ream. Hopefully finish it tomorrow

    Why not bring it in close with the boring bar and make a lap to finish?

    Such as a Cylinder Hone? I'm not sure if the PB would pickup the abrasive. I guess I could hone it while sat in a bucket full of soapy water

    We'll see what today brings

    :D

    It fits. Line bored a thou over then thanks to Pete's suggestion of using a 3 legged cylinder hone, it was honed to size. It needed tapping in, but once rebuilt the hand wheel moves it very smoothly throughout the full range. Well happy.

    No picture as I'm sure everyone knows what a tailstock looks like:laughing:

    I think some machine bellows are in order now.:whistle:

    How did you secure the tail stock to the carriage?

    I see so the carriage was pushing the tailstock along.
