Well, I started off with a Bridgeport M head mill, with the B&S #7
spindle taper. It was a TOTAL PAIN! Although there were some
spindle flexibility issues that also bothered me, the trouble of
adapting all sorts of tooling to that spindle were a substantial
reason for upgrading to R-8. I have stub milling arbors, boring
heads, fly cutters, a wide range of end mill holders (I rarely use
collets anymore) several Jacob's chuck arbors, etc. that all work
much better with a direct arbor, rather than mounting everything
with straight shanks held in collets.

I am a big believer in the R-8 taper as the universal spindle for
smaller milling machines. Thus is entirely due to the wide
availability of arbors, etc. in this taper.
