Power supply questions

I am starting to get some of the pieces of my mill conversion jigsaw
puzzle together.
Motors; Reliance Electric DC Servo motor, Model 0660-04-076, Back EMF
Constant, ke = 68 V/kRPM, Torque Constant, kt = 5.75 lb-In/Amp , 250
line encoder US Digital, Nominal Speed Rating: 1750 RPM, Nominal
Voltage Rating: 120 Volts, 2 Amps
Ball screws and
nuts: Nook 1" x .250 lead
Direct connection using Helical connectors

Gecko 320 drives

Sound Logic Breakout board for Mach 2 (when
ready)
I want to run the Geckos at about 70 volts +/- which will give me
about 1000 rpm at the motor.
I am now working on putting together
the needed pieces for the power supply. I will be using a Plitron dual
115/230, 50/60hz, 1000va/50volt toroidal transformer that gives 10
amps per side. This transformer will give me my 70 volts DC. I know I
will need a capacitor and a bridge rectifier. How do you size these?
Sources? I also have been told that I will need a zener diode of
either 82/90 volts? 5amp fast blow fuses on each of the geckos. Are
there any other bits and pieces that I need? Is there an electrical
layout and wiring drawing anywhere that will show me how to put this
all together? Should the power supply be in it's own enclosure or can
it be incorporated into an enclosure with the breakout board and the
Geckos? Although I am learning a bit about all this as I go, I still
need the help of the experts that make this list so valuable. Are
there any other suggestions/comments to what I am proposing? Thanks
again for all your previous help. I am sure I will have many more
questions before I get this all put together and running.
