For Keurig Mikuru -- this is how I true the crown gear on the spline hub. Like a lot of machining adjustments, it is merely knocked around with a chunk of soft metal until it runs as true as possible. Here, my spindle run-out is 0.001" and my lateral run out is aboy 0.003", which I was not crazy about and trying to minimize in the video. As for welding, I tack first all around, then measure again on the lathe, then make very short, cool welds, on opposite sides, until ive covered the full circle. #machineshoplife #VintageBMWMotorcycles #gearboxrepair
