I am still struggling with making an encoder adaptor that would go
into the top of my spindle (spindle is hollow, with a 26mm hole), and
have a 3/8" shaft protruding on top to mount the encoder disk.

After a few things that did not work, I am settling on simply making
this adaptor out of 12L14. It should be easy to make on a lathe. I am
thinking how to avoid making it "expand" but just stay in place
without expanding.

Whet I would like, I think, is make it fit the spindle precisely, yet
without any significant force involved (that is, not press or
interference fit), but use some weak glue to hold it in place. This is
so that I would pull it out easily when necessary.

Would anyone have any suggestions as to the glue.

Thanks

Wild idea. Turn a groove in it and insert a neoprene o-ring? Not good
enough?

Loctite green is a sleeve and bushing locker. Takes heat to remove. I have
used it with good success for press fit water passage adaptors on engines.

Weak metal glue? Machine your adaptor with a flange so it rests on top, and
put a thin layer of silicone household adhesive on top. Make the flange
square or hex shaped so you can break it loose easily with a wrench. The
silicone will break loose easily, and peal off the parts with your fingers.
(has be be clean and dry to work) Worried about oil later? Use an engine
gasket silicone.
