Unfortunately the 1611 does not have the same kind of baseplate as PC,
Dewalt and other routers. The template bushing fits into the actual
aluminum router base casting, not a plastic insert that can be
repositioned. Another base plate could be affixed to the existing base
plate, at the cost of extending the narrow shanked bits another quarter
inch or so.

I got hold of a PC890 router where the centering process is trivial and
solved the problem that way.

I'm not sure I want to think too much about the geometry of why the
"keep the router in one orientation" approach doesn't work, but it
produced additive errors on some of the dovetails (2-3mm gaps), probably
due to the need of registering one side of the board with the jig at one
end and the other side at the other. Also with as far off center as the
bit is even very small shifts in angle will move the cutter with respect
to the wood.

I had a similar problem with a router base. The fix is simple,

Unscrew the baseplate, rotate a few degrees, then using a centering bit in
insure a concentric hole for the guide bushing, mark new screw hole
positions. Remove baseplate, drill and tap new screw holes.

Or-

Replace all flathead screws (countersunk) in the base with pan head screws
after drilling the taper partially out of the base leaving a flat bottom for
the pan head screw.

Or -

Replace the baseplate with a custom made or aftermarket baseplate. See Pat
Barber.
