There is no way I would run an encoder for the ELS via a gear. I would
suggest that with an encoder with a shaft you only consider a timing
belt drive.
Also why would you want to disengage the encoder?

I will have to come up with a shaft but gee isn't that why we have a
lathe?
Also a mounting bracket I have some 3x4 aluminium angle and some plate
steel
also a vertical?mill and a welder and drill press so I should be able
to come up with something. I can even use the indexed pivot to engage
the encoder.

That option is still available to you if you can get hold of a disk,

Note these are readily available for free, by picking up dead
inkjet printers. The encoder needed is on the left-hand end of the
platen and the sensor circuit is usually a simple U-shaped board
attached to another circuit on there. I have several of these at
home; if I can remember, I¡¯ll post a pic later. There are a number
of online projects recycling these parts
printers are also useful sources for nylon gears, a variety of
springs, small DC motors and steel rods of different diameters
(mostly like 5-8 mm or so) Old laser jet printers also have a
wealth of motors and mechanical parts, but they¡¯re harder to find.
I've scavenged a half-dozen inkjets simply by picking them up out
of the tip.
The scanners on the multi-function ones also provide a very nice
8x12 or so piece of optically flat glass; quite useful for things
like a base for a tool sharpening setup.
