My random thoughts.
I have just started using the R8/Tormach toolholding system and find it
far more convenient than plain R8. Changes are as fast as grab a wrench,
loosen draw bar enough to slide tool holder out, put next holder in,
tighten, done.

My power draw-bar cost me £40, and half of that was because I decided
to anodise the parts.
(My mill was 30 INT as delivered, and is now using BT30 tooling)

I've got an Erickson QC30 on my Bridgeport CNC mill.
R8 does not maintain any accurate Z reference after a tool change.
So while you can change tools quickly, how much time does re-referencing
the Z axis use on repetitive parts?

How long does it take to lower the table far enough to extract 4.5' of R8?
I ad
Im not sure I'd go that far (and Im an owner of both). NMTB/QC30 has
positive drive but a R8 power drawbar absolutely whoops QC30 in tool change
speed & ease. Push button vs having to yank on a wrench both in and out.
Its not really an improvement.

I made a 600+ mile round trip last week to pick up a load of NMTB 30
tooling for $1,000. A very nice surprise was the lot included a
Kennametal Erickson quick change spindle from a Bridgeport. The guy had
swapped it for an R8 spindle so he no longer needed all the 30 taper
stuff. Didn't mention
