Soft jaws made

Here's the CAM toolpath for the soft jaws. I've moved the WCS origin to the top front left so that any error in the depth of the jaws don't affect the dimensions. 

Setting the WCS origin with Z=7.5mm (in G53), using the knee to position the height of the stock. The gap between the jaws needs to be 83mm. I used one of the hard jaws and some ground parallels to achieve 83.3mm.

 Here it is after machining: 

Seems to fit nicely:

Cool. Now to prepare for the "top side" machining.
