The process was no issue to remove some material and re-chamfer the ends on that tube. If you or anyone here decides to take those chinese bearings out and replace them with a better bearing, just drop me a message and i'll give you my shop address. It takes more time putting it in a box and bringing it to the post office, than actually doing the tube work. If you want me to get the press fit correct in the two hubs, just let me know and i'll schedule it in advance. If I schedule it, I can turn it all around in about 3 days. If my boring head fixture is set up, it would make sense to do a few of them at once due to the initial time to set up. The three parts (2 hubs and tube) can easily fit into a large flat rate postal box.
P.S. My tube needed .005 taken and the chamfer on the ends where incorrect. Mine also might have had a maximum of .001 to .002 of chrome on the rim, and two hub ends that butt to the rims. So therefore in conclusion, hubs that are from factory in conjunction with the factory rim thickness, most likely have a tube that is .012 to .014 too long, and that's absurd.
You can do one or two things to determine this. Take one side hub off and with two sets of feeler gauges, lay two down of the same thickness, set the hub back on (no bolts) and see what it takes for the rocking of the hub to be gone. This will get you far more closer than what the factory did.
Dam nice work
