	Right: The parts, plans & supplies for the project Below: Note the scale of that spindle! It's a monster . . . 45#


	Right: AutoCad Model of the belt/pulley gear reduction, spring loaded, motor bracket. Below: Plasma cutting the parts from 3/16" steel sheet. Below right: the Motor Bracket assembly for X axis.


	Right: X motor bracket in place with motor bolted up & Small Block Chevy double valve spring in place keeping the Pinion firmly in the Gear Rack. Below: The turned Motor Bracket main mounting shaft housings.


	Right: Turning a Motor Bracket main mounting shaft housing.


	Far Right: Assembled X motor bracket Below Right: The X axis pinion gears needed a keyway broached into it because of the hi torque of the motors. The Broach with its spacer for the 3/4" shaft. Below Far Right: Cross drilling a shaft.


	Above: Broaching the Keyway in the X axis pinion gears. Right: X motor with key and pinion gear prior to broaching. Far Right: Motor Bracket and parts


	Right: Gear reduction shaft for X & Y Pinion Gear.


	Right: AutoCad Model showing the Y motor bracket.


	Right: Y motor bracket


	Far Right: Y Motor bracket rack & pinion--tight clearance between pinion face & rack mount tube. Right: Turning end of the the Hardened ball screw for the z axis to fit in the Lower Thrust Bearing. Below: the Z motor with its coupler & the Z ball screw. This system will need an electromagnetic brake for the Z axis as the ball screw will back-drive the motor when power is shut off to the motor.


	Above: Z axis ball screw nut at Z carriage attachment plate. Right: Upper Ball screw mount plate & bearing Right Lower: Lower ball screw mount plate & thrust bearing.


	Far Right: Y/Z carriages assembled & mounted.
