Converting a Grizzly G1126 Gear Head mill - need advice

I'm in the process of converting a Grizzly G1126 Gear Head
mill/drill to CNC and am "lining my ducks up". I would
appreciate any advice from anyone out there who has experience
with any of the items below. I'm new to this group and have
been reading it for some time, this is my first post (plea
for help!?). The reason for choosing some of the items
below (motors, controllers, AutoCAD, hyperMill) is I am
getting them free from various kindly benefactors.

The whole flow looks like this:
---------------------------------------------------------
SOFT:
Design:
Autocad (not sure which version yet, I'm getting a "cast
off package from a friend who has a "real" CNC shop and
goes through software like popcorn in his quest for the
perfect package).
|
G-code translation:
hyperMill --- anyone know anything about this package?
Any help would be appreciated in terms of what CAD package
you're using it on etc.

|
Machine control:
Flashcut --- same goes here, anyone using Flashcut, what
are your experiences with it?

|
----+----------------------------------------------------
HARD:
Direction/step signal provision:
Flashcut signal generator
|
Motor control (x,y,z):
(3) Pacific Scientific 6410 controllers
|
Motors:
(3) Pacific Scientific stepper motors
K31HRHH-LNK-NS-00
NEMA 34 mount / 4 lead / 1 rotor stack
2.8 Amps current rating (DC) BIPOLAR
Holding torque 845 oz-in (5.96 Nm)
|
Motor coupling to mill:
NOT A CLUE YET on how I'm going to do this in terms
of mounts and couplings and any pointers to suppliers
etc would be helpful.
|
Mill:
Grizzly G1126 Gear Head --- any comments on this specific
Grizzly mill would be appreciated.

makin' stuff! ... we hope :-)
---------------------------------------------------------

This is strickly "me in the garage, screwing around in my
spare time type stuff" so you need not take any "production"
requirements into account in any evaluations.

AND ... lastly.

How do I get this damn gunk (cosmoline?) off the Grizzly
and get it spiff'ed up. I just got it and wrestled in onto
a bench with an engine hoist yesterday.

If most of the above has been labored to death in this
group in the past (I haven't gone back and read all the
previous archived posts) then please email me directly

Thanks to anyone/everyone in advance. It's a big project
for me but am looking forward to getting stuck in!
