Gearbox details
The worm gearboxes are brand new never used. They are imported from Italy from Motovario part# NRV#030 ( I got mine from CBC Bearings in Melbourne) cost $160 each!
Aluminium cast body about 75 x 75 x 60 with a 8mm shaft output; 60:1 ratio
Full ball bearings and as smooth as velvet!
Was about to use them on the 445mm scope with a final ratio of 20:1 to give an ideal Bartel microstep of less than 0.5 sec arc.
Can post photo at weekend.
