  We left off with the rear wheel hub being machined on the Lathe in the last update. Here is the completed hubs

  On its side is the smaller of the two hub pieces

  A quick test mount of the hubs with the rear wheel is promising

  This is only the small half however, and I still needed to drill the lug bolt holes in the larger half, so I lined them up together with the central hub piece keeping them in line

  The result, niiiiice!

  Next lets try the whole thing out on the mockup of the rear axle

  The bearings came in, which required a recess to be machined out of both hub pieces on each side. Here is the smaller of the two hubs with the race machined out. I will note that aligning a piece like this on a four jaw chuck (at least a not very good one) is a royal pain in the ass

  And now with the bearing tapped in - Nice!

  Both sides done now (after another hour or so of aligning in the four jaw chuck). There is a reason for this over engineering which will become apparent later in the build

  After that it was time to tackle the other half of the rear wheel hub and machine bearing races into that one. Here is the completed product.

   

  And now the same test, but this time jigging up the rear of the bike to the rear axle mounts...Woohoo A rolling rear wheel!!!

   

  As you can see, the rear frame of the prototype still needs quite alot of work, this has not been finished welded because the drive train is still being determined and then will have to be constructed, and this prototype will be a hardtail (no rear suspension). The current state of affairs...
