Please allow me to reiterate;
I'm doing design artwork for the guy at the pro-machine shop, who has years of experience producing military specification assemblies working with steel. In return for my design work - I asked him to help with the shaft (which doesnt mean 40 hous of labor).
Its up to me to do my reseach first; and know what to do.
My idea is to create a shoulder on the drive-side, and match the turned-down o.d. shaft to the i.d. of the bearing, and then create threads for a flange locking nut to pull the shaft through- and solidify tight on the motor side, much like a collet assembly locks into place by using two wrenches.
He has all the other jigs, clamps, vises, arbor presses, and bearing pushers to press any size shaft into any sized bearing - in addition to a 100% accurate set of measuring tools.
Those bearings are used in lots of heavy-duty machines; I see. And it has plenty of rigidity. Using a larger bearing; such as 5/8 bore, with a wider length-grab is also an option, as I can turn down the shaft and have a sleeve made to match a larger bearing.
This upgrade would mean alot to me, however - I do not expect it to work more then 6 months.
