A couple of weeks ago I finished machining the final part for upgrade and disassembled the Y and Z axis. Here are a few photos of the new bits coming together.

1. Z stepper motor mount and side pieces which hold the Y axis ballscrew


2. Z axis main plate


3. Y axis main plate


4. Z axis rails and ballscrew coming together



5. Converted a linear bearing housing to clamp the 80mm spindle (as posted by others on this site)

Removed circlips, knocked out bearing, machined slot in one side, drilled 2 new holes to make 6 in total, counterbored to suit M8, job done.
Plan is to fit 2 long blocks onto the Z axis plate either side of this clamp so that if I ever index it up or down the Z axis it will remain aligned.

Still bits and pieces to tidy up, new spindle strain relief bracket to make, tidy hoses etc. but have already cut out my first new part and it does seem to be cutting better than before.

Might finish this thing one day . . .
