Reply to "How difficult is it to convert trucks to use roller bearings?"

I bore out the side frame journals with a series of reamers until I get to few thousandths under 3/16" and then I press the bearings into the side frame.  One thing that is critical, the shoulder your axles needs to be 3/16" diameter.  If the shoulder is smaller you'll need a different bearing.  Same thing if you axle shoulders are larger.

You can use twist drills but they tend to grab the material you're boring out.
