I think the upright is finished. One side effect of building the upright in two main parts, which I'd forgotten, is that there is no need to have two separate designs for nearside and offside. Those of you who look carefully at the finished design will spot the method for joining the two bits together. The aim is to mill a round-ended slot in the upright and have an identical mortice in the top extension. Ideally this will be a light interference fit (one of the joys of CNC is that you can do this sort of thing without the need for extensive grinding) which is further located by a pair of dowel pins for added strength. The cutaway below shows the joint a little better:
According to SolidWorks, that complete assembly weighs around 4 kg (and in reality probably less because the calliper has more volume than the real-life item. That's not too shabby, especially since the FEA results are looking fairly reasonable. I'm tempted to use a bit more mass and reinforce the upright slightly by reducing the size of the central hole in the purple bit. Now all that's together I can hit SusProg and get on with firming up the suspension geometry. After that should come the suspension hardpoints on the chassis and the chassis itself.

I'm badly looking to find the solidworks file of a wheel hub. I was just wondering if you have one ready or know where to find it. my email is hma40@sfu.ca
