Yep, but with 3 and 5-flute tools, different v-blocks. I have the height
gauge. I can also do the check on the Darex, but I would have to mount and
check 'good' tools that way, too.

Again, I was looking for a sort of "shop craft" method. Apparently, none
exists, or is so old as not to be employed anymore.

Why would you need different v-blocks for 3- & 5-flute tools? From a few posts ahead of this one:

Mic the shank diameter.

Place shank in V-Block, put dial indicator tip on high spot of shank (center) and zero out indicator.

Move indicator to flute, measure high spot on flute, difference between shank and flute reading is radial value that value X 2 gives you the difference in diameter.

If needs be, check each flute to see what the run out may be.
