Automatic or easier tool changes for R8 mills ?

Hi people.

We are getting tired of changing tools with the manual drawbar on our
R8 equipped CNC'd mill. Does anyone have any experience/ideas with
implementing a quick or automatic tool change with R8 collets ? The
first step in the automatic change would be to come up with some sort
of quick change collet system.

I know of two: the air wrench powered drawbar looseners/tighteners and
the the Royal system whereby the R8 collet is a holder for another
collet system.

I'm thinking something along the line of adding a pull nipple on top of
the R8 collet and pulling it up with an air powered drawbar something
like how the Cat40 system works.

Failing to find something that works for the R8, our next mill will
have a Cat something taper...

Thanks.
