I want to install bearings (R8 2RS) in both ends of a 1.5" piece of aluminum round bar that is 2.00" diameter. In a 3-jaw, I face it, bore 3/4" through, then cut the first recess. Remove from chuck, reverse, cut second recess. Then install the bearings, with a light press fit, Any tips on improving the accuracy? The .5" shafting never fits as well as the individual bearings do on the shaft. I have a Grizzly 4003G with 3-jaw and try to reverse the piece as best I can but feel this isn't the proper way to do this operation. Ultimately, the 2" round "hub" gets installed in a woodworking project not requiring high tolerance or subject to high load, but I still want to do the bearing installation as best I can, and ultimately would like to make 50 or more of these. Thanks in advance for any suggestions.
