Refitting the toolchanger turret assembly

Things are a bit tight in the workshop at the moment. It was bad enough before the Tree lathe turned up. Now it's pretty tricky moving the crane but luckily I can move it enough to be able to hoist the toolchanger into position.




Almost there. There are a couple of locating dowel pins underneath, so once the piece of wood is out of the way, it will be positively located 


4 large bolts secure it to the cross slide. And I've reconnected the switch wiring to the umbilical. The cable is routed up the drag chain along with the various hydraulic hoses etc.


Talking of which, here are the 3 hydraulic cables. The middle one is simply the coolant hose, which terminates at the manifold block on top of the turret housing.


The umbilical cable doesn't seem to have anything to mount onto. Looking back at the pictures I took when dismantling, I can't see anything missing. I'm guessing somebody has been in here before and removed a bracket of some form. Cable ties it is, then.



Here's the other end of the umbilical. The boot ferrules are not of the same vintage as the original wiring, so clearly the controls have been changed at some point.


That will do for now. I won't be able to test it any further until I've got some of the electronics installed, such as the main Acorn controller and the VFD that will be used to drive the hydraulic pump.

Final assembly and test of the spindle nose adaptor - RESULT!!
