I almost finished the lathe work:

Famous last words ... took me most of last weekend to actually finish the turning:



I double checked all the diameters now it is off the lathe and it's well within tolerance - e.g. the longest diameter is 0.011mm different from end to end, but the drawing specified up 0.04mm here.
Next step is to mill 3 keyways in it and drill some holes for the sproket.

We also got some new brakes delivered from PFM. Apparently they're really good ... I don't know about brakes.
