One of the finished hubs. Was surprised National calls for 5 thou interference fit on they're seals, seams like a lot.
Was given that boring bar Ed. it has interchangeable ends, with a jack screw to adjust the offset, like a boring head in a mill. the other ends have inserts with no chip breaker. never could get them to cut well.
This is a boring bar I made to cut out the bearing housings on an excavator after I welded them up to repair wear. Its about 2 inch in dia. and takes a 1/2 inch cutter.

Free advice is worth exactly what you payed for it.
