Since I will not be needing any simultaneous 3 axis machining to build the Z axis conversion, I can make do with a 2 axes conversion. The X axis is held in place by a simple aluminium bar fixed to the T-Slot. An action shot which shows the 2 axes working together can be seen next.

The workpiece has been raised so that the entire profile can be machined without damaging the machine bed. In this picture you can see the way that both the X and the Y axes are mounted. The Z axis is done manually for the first few parts. This does reduce the abilities of the mill but it is only temporary. Great care must be taken to avoid fast travels between separate milling operations.
