I hope to learn more about machining over the summer. Our mechanical team knows how to run the mills but to different extents (and we use a digital readout that holds .0005" of tolerance, although not sure how accurate it is).
I will probably switch to using those flanged bearings.
I am using hex key turned down at the ends for all of my shafts and was wondering how good of an idea it is to turn down hex shaft like that. I would think that all those edges banging against the bit can't be good for it (although if I came in from the side that would be solved. This is what I have done before but the AM hex shafts already had an end turned down onto them.).
thanks,

EDIT: Is an arbor press absolutely necessary for press fit bearings? Could the same effect be achieved without too much trouble with a vice or some blocks of wood and a hammer? I am not against getting one, it seems like they would be quite useful. It is just that we can't really afford luxuries right now
