Hey guys! I've got the pieces I need to build my welding positioner/rotator.
I want to have a spindle bore the same size as the hole in the chuck.
It's a 2" hole.
Yup.. I could buy two big pillow block bearings and run the shaft through this.
But the shaft OD will be 2 1/2" minimum....more likey 3" OD as 1/2" wall DOM is the only suitable material I've found so far.
I'm not really liking the pillowblock idea. Those size of PB's are huge. So are flange bearings.
I'd like to streamline this.
RPM's will likely never see over 30 or 40 rpm.
Bronze or brass bushings would work....but what kind of housing?
Any ideas would be appreciated.
I know someone here will think of something I'm missing
