New CNC Mill on the horizon

Jonathan, Thanks for that I will do that and see what its like :) I do always use a drawbar with my mill head as the last thing I want is the chuck dropping out and hitting me let alone the piece of metal I have been working on for hours!

I got on to machining the front side of the y axis plate and it again went very well, managed to get the surface nice and level even though it had to be done in two sections as my mill table is not long enough for one pass.

I then milled the base of the bk mounts and the ball screw holder to get the whole thing to close up a bit more without hogging out more of the aluminium plate than I needed to. I only took a couple of MM off the feet of the bearing mounts but it meant I did not need to cut into the face plate at all.

Ignore the lack of bolts I am waiting on a "top up"

Looking at your picture, you have the Z ballscrews bearings bolted to the fixed Z plate, and it looks as if the ballscrew nut will bolt to the moving Z plate. How are you going to adjust the nut or bearing position, or the guide rails, so that everything is nicely aligned? I've been looking at these details on my own design for a while and am looking for inspiration! I have some ideas, but always keen to re-use other people's work...
