OK I bit the bullet and made a tool collar setter last night. It
unfortunately relies on the collars being the same thickness so I
measure them first.

I have uploaded pictures to the photos section in the folder 'AWEM'
which show the setting tool, and some drills and fish tail cutters
adjusted to equal protruding lengths.

The collar is trapped between the coarse threaded male thread and the
longer hexagonal part, and the tool pushed through by the finer screw
until it touches the dial gauge plunger. To make the tool extended
length the same as another all you have to do is insert the first,
zero
the dial gauge, then fit the second and adjust the fine screw until
the
gauge again reads zero.

Works a treat ! Although shown with a digital 'dial gauge' it works
equally well with an analogue one as the mounting stems are a
standard
at 8mm.
