At last! Something that's finally starting to bear a vague resemblance to Mendel! I tried mounting the x-axis but the z-axis rods are pretty tight and will almost certainly jam :( I suspect it's because they're galvanized steel rather than BZP, they don't seem to rotate within an M8 nut very easily when the force of the x-carriage weight is applied. It's easy enough to replace those two bars with BZP but it'll require another trip to the shops this weekend. I've left the x-axis off for now.
One thing I have done that's different to the instructions is to mount the 624 bearings into position on the the zaxis pieces before attaching them to the z axis rods. Accurately positioning them and tightening the six M3 bolts that hold them in place was just a bit too tricky otherwise.
