	Below: Sketches of the C gear housing Below Right: section through A/C head Below Far Right: wire frame view shwoing all of the pulleys & parts.


	Below: sketches of the gear redection pulley & belt system Below Right: wire frame view showing the pulley/belt arrangements. Below Far Right: Rhino working model--the original coolant radiator can be seen in the upper left for that original water cooled spindle.


	Above: sketches & misc calcs of the gear reduction system and ideas for the X axis hard stops. Right: Good thing the chinese don't have symbols for their numbers! Below: C axis chaft & bearing bolted to the lower C housing plate. Below Right: Plasma cutting plates Below Far Right: cnc layout sheet for plasma cutting.


	Above: gear reduction pulley machining numbers for the lathe. Above right: the C axis shave with the seal pressed in the housing plate. Above Far Right: C Shaft in its mounting plate test fit into upper housing plate and bearing race. Right: the A axis shaft with the squaring rod in place checking for alignment. The center of the A shaft will be cut out once the ends are machined for bearings and nuts and it is welded in place and the alignment is checked a final time. Far Right: cross drilling the A shaft for the squaring rod.


	Right: the C shaft with the milled flats for the set screws of the pulley. Far Right: Setting up & aligning the A axis shaft for final welding using the squaring rod.


	Right: Milling the C shaft flats for the reduction pulley set screws using the 3 axis & generating G-code in the YZ axis instead of XY.


	Right: the A axis belt reduction housing face plate & the reduction pulleys--they are milled separately & press fit on the shop press. Far Right: the A & C housing plates.


	Below: Machining the A & C reduction pulleys from a stock rod. Below Right: C housing bolted in place Below Far Right: The A & C axes in place.


	Right: A little motion test here of the a/c axes . . .


	Right: Gear reduction systems completed for the A & C axes.
