Communicating water level 77

I've posted this in a BC axis thread But to try and keep it all together I should post it here also.

I managed to get a few or things sorted with my BC head along with the rotating nut this last week.


Basicaly I' shortened the two axis to make it more compact,40mm on the C axis and about 30mm on the B

You can make out here how far the stepper is recessed inside the housing(the machined square in centre), this housing is mearly a means of connecting the two turntables at right angles to eachother.

A shot showing the housing upsidedown, harmonic drives and steppers bolted inside.

The square attached to B axis is two pices of 12mm plate, one will be welded to the end of the 150 x 150 x 6mm RHS of the Z column, the other bolted to previous after machining for any error in alignment from horizontal in both planes.
