I have been working on a rather large makeblock installation (I have ran out of screws now!)
It is a 1-stop milling-and-drilling setup to create PCBs in 1 go:
It uses the 8mm linear bearings + the threaded rod from a thread-drive pack, together with new stepper mounterplates, backlash compensation and a longer threaded rod I got from a local hardware store. The drill & mount I still had around - ordered them from germany about a decade ago.
The resulting board so far ->
This was milled using a 1mm router bit (way too big!) while I am waiting for the post to arrive containing a set of fresh 0.1mm v-groove routerbits.

To be continued!
Very impressive use of Makeblock. Are you finding it rigid and vibration proof? On my X-Y drawing bot I get nuts vibrating loose - I can see why Makeblock have added nylon locknuts to the range.
It is quite rigid - in certain areas. The rods are a bit too long for this purpose - they tend to be a bit flexible in the middle. I shall have to make some shorter ones or wait until makeblock starts selling them shorter.
The screws are fine so far (and I already have a the nylon locknuts here as well )
What really helps is not making it vibrate in the first place by having proper acceleration and the flexcoupling on the steppers
