I reground the cutter (6mm single flute) freehand after the Z-plate as it was chipped. Better finish than ever! :surprised:

All the bits made, mainly drilling and tapping to do now then check it all fits properly.

So close now

Something worth noting for the future is that the aluminium flat bar is nowhere near flat, so in future I will stick with getting aluminium plate like I used for my machine.

The BK support is partially dismantled in the photo as it's not going to work without modification. Glad I never considered using them on my machine, too much trouble compared to just making the whole thing.
