Here's the Dewalt DW660 laminate trimmer
mounted on the Z-axisl. The base of the mount
is a modified Taig riser block.

I wanted the centerline of the tool to be in
exactly the same spot as the centerline of
my treadmill head. I mounted a plate with
a piece of tapered, sharpened drill rod
exactly .500 pointing up from the mill
table. The plate had one screw and
T-nut to clamp it to the table. To begin
I left this loose. I brought my treadmill
head with a .500 arbor on Z down over this
"plate with pointy drill rod" letting it center
itself. Then I clamped it down and took
off the treadmill head and replaced it with
the DW660 mount (everything complete
except center location and bored out hole).
By bringing Z back down until the "pointy
drill rod touched the underside of the lower
collar mount and then giving the top side a
little tap with a hammer I left a centerpunch
which enabled me to bore out the collar to
match the DW600 position when mounted
on Z to the treadmill head working center
(...I was "quite pleased with myself it's within
a couple thousandths :-)"

... and from a different angle showing the
modified Taig riser block.

Yet another angle showing the two allen
screws through the riser which secure
the lower collar.The top collar (which
clamps the body of the DW660) is
mounted to the top of the riser block
with two 10-32 screws in short slots.
This allows me to snug up the collar
to the body shape without deflecting
it relative to the lower collar.

and another

I made the collars by leaving them solid and
hogging out the center hole/shape with a
boring bar (in my larger Grizzly mill). Then
drill for appropriate tap on both sides. Drill
again just past 1/2 the diameter with a
clearance drill. Then separate the two
halves with a very small (.125") end mill
running multiple passes. The idea is not to
take too much in order to separate but
to leave clean surfaces behind (why I
didn't use a hack saw).

It's rock solid on Z ... I don't know how long
the Dewalt will run without concern about
burning up the motor (hours for contouring?).

I've run it for @30 minutes continuous and
it did not seem to be "unhappy".
