Need Help!- Greetings from Belize first build

[belizewood]

Greetings from Belize,
I am a high school woodwork teacher at Ecumenical High School in Dangriga, Belize. I am building from scratch a CNC wood router. As you can imagine the school does not have funds for this kind of project, it can hardly pay for wood.
Body made from ¾” plywood, linier slides are off-cuts of aluminum angle from window makers and bearings from router bits.
There is no CNC in Belize, therefore I am seeking assistance outside of the country. My biggest problem is the driver board, we have no electronics shop to purchase/donation of parts from.
At present I am scavenging stepper motors from old large printers, but I am only getting small 48 step motors. I am looking for NEMA 17 to 23, 80 to 305 oz-in.
Therefore I am asking for any surplus parts you may have that can assist this project. Let me be very upfront, we have no money for parts, and no money for shipping.
Thanks in advance for your consideration.

Belizewood,
Have you a design for your router?
If not, look at the JRGO, Sosylva, and Joes2006 designs. I believe that if you set a goal you will get donations from folks who have built one and had parts leftover, or just wish to help.
All use plywood or mdf as the major structure. They also use gas pipe or angle as rails, and skate bearings for linear travel.
Post a design, or pick one so we know what you need.

Belizewood,
Looks like you are off to a good start.
What parts are on your critical list?

[belizewood]

My biggest problem is the driver board

I am also looking for NEMA 17 to 23, 80 to 305 oz-in.

[BobF]

Do you have Screws?
If so what pitch or lead?

[belizewood]

BobF,

I am using all tread 1/4" x 20 tpi with bearings from a roller blade,

will take picture tomorrow when I get to school

[BobF]

OK,
Smaller higher speed motors will work better for your screws.

BobF,

This is how far I have got,

can you solder?

[belizewood]

Yes, simple stuff but it's been some time.
