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)
