Karl, can you contact Excello?

Looks like it may be time for me to find them and buy that manual. I've been
lucky and never needed special parts. But, I bet the parts manual won't show
enough detail to count teeth. By chance, does anyone know where they are
located?


Are you positive you have just one set of gears operating here?

I'll guess that its a compound reduction. After all, you don't have to
reverse the motor when you go to back gear, like on the older J head
Bridgeport machine. BTW, I just noticed an error in my post a ways back.
This machine looks a lot like a Series 1 CNC Bridgeport with a 2J style
head.

Right now, I'm a cogitatin' on how to mount an encoder in a tool holder.
Then run the machine and get the ratio out to the sixth decimal place. Seems
easier than tearing it down. Then use that real nice gear calculator Marvin
offered.
