Greetings all;

Hooking up the encoder so I could use it to calibrate speeds obtained, I 
am puzzled as can be. But let me put that pix up on my web page first.
Got it, could be sharper but will do.  

Append "/lathe-stf/Encoder-installed.JPG" to the link in the sig.

The curved alu piece as you can see has 3 trenches carved across the 
inside face, on a curve radius that matches the bull gear.

And as you can see, looking at the top 2, one is dead centered over a 
tooth, and the next one ccw from the top, is dead centered over a valley 
between the teeth.

The index I had to fool with as it was seeing not only its 
special "tooth" but all the other teeth too, so I had to break its glue, 
slide it to the left a couple mm's at which point it quit seeing 
anything but my screwdriver going by.  Had to make a new special tooth, 
bigger & set a little proud of the bull gear teeth.

Getting all that fixed, I put a hal meter on the velocity pin and got 
pure noise turning the chuck with a crescent wrench on a jaw.  Hooked up 
the halscope, finding the a/b outputs are almost perfectly complementing 
each other. No quadrature at all.  Those are ATS-667's you can see, body 
end in the top two slots, lead end as the index one is reversed in the 
mount, and sitting about 3/8" out into the other block of alu holding up 
the pcb so I can attach the cable to it.

Given the mechanical quadrature spacing you can see, what the heck is 
going on? I am thinking maybe I need to remake the alu holder out of 
iron/steel to make the iron in the mount shield them from each other 
better?

What can the rest of you see that I did wrong?

Thanks everybody.

Cheers, Gene Heskett
