Grafting feedscrew (Q from a new guy)

[Pete O]

Thanks Steve, I have been mulling this over and thinking about where I would end up if I have problems assembling the shaft with a shrink fit. A size-for-size slip fit with some 620 and a taper pin would be far less likely to end up an expensive mess. I don't have the capacity to cut gears to replace the drive portion of the shaft if I damage it.
