Sure it does, his encoder will operate just as well on a hollow shaft as
on a solid one...

Not if its plugged into the top of the spindle with an expanding
arbor......

yep, me thinks Iggy be making a mistake to lose his hollow spindle
just for an encoder. There are ways around it.


I see this thread hasn't mentioned spindle speeders. I use a unit that
mounts just like any other tool and the ouput shaft turns 6X the input
with a set of small collets. Scored mine on the bay for $200 and
change.

I thought I included at least one in the links I provided.

On the Gorton mill Im currently using...my top spindle speed is 5000 rpm
So it will push one of those for up to 30k rpm

The more you present a leftist with factual evidence
