Well i got the stepper motors yesterday and the ardunio board and easyboard (stepper controller) and worm gears today. So I have soldered everything up and i am currently using the SGL focus control to test the motor everything is working well.
On the worm gear side of things i went with plastic Worms and Gears - 24 Diametrical Pitch (Series 1). a 20 tooth gear for the AZ axis and a 50 tooth Gear for the Alt axis. as is these gears will fit right in place of the existing control knobs so just need to thread them right and they should screw right into place.
no need for adapters for the gears.
The motors are another story, one of them came nonfunctional out of the box so i am going to email the supplier to see if i can get a refund/new one. The other works perfectly so i might try to design an adapter that will let it site 90degrees t the worm gears using the existing losmandy bolt holes. this might also allow me to use one engine and shift it between axis's if i can't get a new one.
so far total bill stands as so
Ardunio board from JayCar - $30
Easycontrol board - $14
Stepper Motor (only counting the functioning one atm) - $23
Plastic housing = $8
Worm and Worm Gears = $32
Total: $107
I estimate the cost of fabrication for the adapter for the motor will probably be in the $40 range. So might come in under estimated budget of $200
