while the 99% scream about politics, can the three remaining people who
remember anything about metal and working chime in here?

I use a chucking reamer to make accurate holes after drilling them on my
lathe (these are adapters of various kinds) - I center drill, then drill,
then put the reamer into the drill chuck to ream. But there is a
problem - drill chucks, even on the best of days are not high precision -
the spec is .015 runout measured 2 inches from the chuck at 1/2 max
diameter (from the Jacob's site) - so with a chucking reamer that is 6 to
8 inches long, that .015 becomes a much more significant number. The
answer is, of course some kind of floating holder - and I can get ones in
various configurations - so the question is, what makes sense? Glenco
makes nice units with a MT3 (male and female) so one can put them in
series with the chuck, there is quite a range of other units

thoughts, about this subject please (no politics - let's see if it's
possible)

I use kennametal floating collet chucks, they work well in both the
lathe and drill press. They show up on ebay on a regular basis.
