In the previous installment, I'd mostly completed the mill head and put power to it, only to discover the spindle was bent.
Well, over the course of this past week, I was able to order new bearings, and after careful consultation with the Internet At Large- which, I have to say, is often like trying to interpret tea leaves or chicken entrails- I decided to simply machine the spindle back to 'round'.
The OD only took about .009" to clean it up, plus I faced it and touched up the OD chamfer. The collet taper I bored carefully using the compound, and will touch it up by grinding once the spindle is reassembled.
I think it'll work.
But, maybe sometimes one should look a gift horse in the mouth, eh?
