I got the run out down to approx 10 thou or 0.25mm so that's not too bad. The needle on the dti flicks a bit but then it's an old rim with lots of dings around the sides. An offset of 36mm from the edge of the hub puts the rim in the centre of the frame.

24 - Wheel Building
I built up the back wheel today, it was lying around for ages. I was going to make a new liner for the hub, but what I've decided to do instead is to re-line the brake shoes with a thicker material then skim it down to suit the hub. Before I could do that I had to put the hub on the lathe and remove a little lip which had formed on the edge of the old brake liner and would have stopped the new shoes from going in.
