Hi Rod,
so it seems there are two of us :-)
My reduction is made of two worm gears (1/180) that I found in the misc bin in my friend's machine shop.. He found them on some other waste and decided he should store them for a while :-)
Also, the telescope's hor wheel rides on the 12mm shaft, driven with the worm gear..
I have seen a lot of epoxy gear solutions on the web and this is something I would have adopted if I had not have this solution.
Just be careful how the whole thing is put together, you will want to have the same portability as it was before bartelization.
Apart from couple of hickups with the software ( I have some funny issues with encoders, but I managed to circumvent the problem, partly with the help from yahoo group and Mel himself), the system works great, and it does not cost heaps of dollars, like some commercial systems out there, the price/performance ratio is excellent.
Good luck with your project :-) I would be very glad to assist, if you need any help :-)
