If you look closely at all the unimportant bits which are just left with rough sawn edges it would possibly look less tidy. It is big and shiny though.

Right I think I have fixed the Z-axis binding problem - it was just not aligned right - rather than adding shim I shaved a couple of mm off the ballscrew support block and it is now good.

However it is running so smoothly compared to the Y axis, it rather indicates that there is something wrong with the Y- axis... I need weekends with less work in them.
