I have one that I am going to install on my Legacy 900 Ornamental Wood
Router. It has a 3/4" acme lead screw on it that moves that router
down the carriage( x axis). I wanted to have a readout showing
fractions and decimal values. I am going to mount the second encoder
on the y axis. I realize that it is not as accurate as what a milling
machine might have with glass scales but I think it is going to be a
great addition to this machine. Since I do a fair amount of
woodworking I can think of a few other applications like on my panel
saw and my cutoff saw. I will post with updates.....
