Ok, I tried making a few stopped flutes which terminate with a taper
using a wedge as discussed in a previous thread. (Suggested by
SonomaProducts)
Here is the result:

Came out ok. You can definitely see where the taper begins in the
flute (not a completely smooth transition). This can probably be
fixed with a piece of sandpaper or just leaving it alone.

Yes. I noticed this problem. My router PC plunge is round on one
side and flat on the other. Initially I was climbing with the round
side and it had a tendency to wobble as you stated. I flipped my
fence to the other side of the router and climb with the flat side.
Much easier this way. Good tip.

Think of a flute as a specialized version of a mortice.
You cut a mortice with a plunge router using a home made morticing jig
that clamps to the workpiece.
You can use the same concept to cut a curved flute.
Build a jig that attaches to the router with side runners that capture
the stock thus preventing router rotation, but slide relative to the
workpiece.
These runners can then also follow a guide that contains the required
curve to to provide required curved runout and are clamped to the work
piece like a pair of vise jaws.
The only thing left is to provide a means to index the router for
multiple flutes which requires the router to move cross wise to the
jig.

That's a neat idea. Have you made this jig?

nice job. rather than sand, i'd practice a few more, and try to hit it
perfectly. sxomehow sanding makes it worse (when I do it)

Not a bad idea. I think this is what Leon suggested above. In the
process of making more practice cuts, I found that with the radius'ed
wedge and a feathered edge on the wedge works nicely. Coming down the
wedge seems to be the best approach.
Interesting note, that in discussing the tapered stopped flutes with
the client, he wanted tapered stopped flutes on both ends of the flute
(Uggghhhh)
I would need a ramp at both ends (go down and then go up a ramp).
Fortunately, I talked him out of it.
Bothe ends is how I've always done it.
... The customer is always right (and a pain inthe ass)

Yes. I noticed this problem. My router PC plunge is round on one
side and flat on the other. Initially I was climbing with the round
side and it had a tendency to wobble as you stated. I flipped my
fence to the other side of the router and climb with the flat side.
Much easier this way. Good tip.

Morris,
HUGE improvement!! Thanks. The router climbs with greater ease now
and the end result is better. It is a much natural climb and the base
ouf the router doesnt slam to a hult when it hits the wedge.
Check out the result here:(under reply)
http://www.garagewoodworks.com/shop_talk.php
I might play with different radiuses
Thanks again!

Hmmm. I'm not sure at the moment how to make a wedge with a radius,
but I'm sure it can be done. I need to think this one over.
Even though the wedge is knife sharp, the router base still stops when
it hits then I lift and climb. At the transition point in the flute
it almost makes a step. It's as if any edge in the wedge is magnified
in the flute. I need to think about this one. Thanks Morris!

Have you tried it the other way ? Start from the taper and work into the
flute .

I appreciate your candor Leon. It is difficult to control/prevent the
shutter. As the base fist hits the wedge (which is knife sharp) it
stops and then climbs. This is mirrored in the flute. You can see a
tiny 'step' in the bottom of the flute before it transitions to the
climb up. I was able to make the step less noticeable with sandpaper
by curling it into a radius that complements the flute. Not sure what
I will do yet. The neander method of using a gauge might look nicer,
but I dont own any gauges. :^|
Hmm, I don't recall having these problems but it has been a while
since I used this detail. I just did my own fireplace and would have
liked to do it but was in a bit of a hurry with other pending projects
so I just did standarad stops.
I do recall that I usually used a very large add-on base on the router
to add more heft to the router so maybe the inertia overcame the stall
at lift. I think beveling the front edge of the base and using a
radiused ramp will both be added to my repitoire.
Really nice work. Such a small little difference but it will please
your eye forever; just like my round ended flutes on my firplace bug
me every day... :-(

Hey. I think the best solution might be to combine yours and Morris's
idea. Climb down the radiused wedge!!!

Oh, I see what you ended up with. You hollow-ground the edge to
quicken the transition a bit. I thought you might be hanging up on
the opposite edge, the 45 degree away from the point, hence my
original post. Mea culpa.

Something you might also try. If the router is on an auxilary base, bevel
the leading edge that meets the wedge to the same angle so that the base
does not have as abrupt of an edge to catch.

IMHO the stopped end looks better with out the taper. And you don't have
the shutter as the router changes direction.
I have an example on a.b.p.w.

I have practiced about a dozen times now and always get the same
result. I even tried waxing the lip of the wedge and it doesn't
help.

For a quick radius, round it on your 1" belt sander with the backstop
(fence?) removed. Then sharpen the tip of the wedge down to a micron,
Brian. Voila! No transition marks.
P.S: If the wedge is thick/tall enough, there is no need for a radius
as the bit will be clear of the work before it gets to the top.

I appreciate your candor Leon. It is difficult to control/prevent the
shutter. As the base fist hits the wedge (which is knife sharp) it
stops and then climbs. This is mirrored in the flute. You can see a
tiny 'step' in the bottom of the flute before it transitions to the
climb up. I was able to make the step less noticeable with sandpaper
by curling it into a radius that complements the flute. Not sure what
I will do yet. The neander method of using a gauge might look nicer,
but I dont own any gauges. :^|

As the router starts to climb the ramp, it is only supported at two points
due to the round base plate. Using a square baseplate will make transitions
smoother.

Heh. Nice idea! I will try this.

I think the source of the problem is the abrupt transition between the
flat surface and the wedge. A three-fluted bit /might/ (or might not)
help with the slight side "dwell" marks at the transition.
If I were trying to do this on the CNC, I think I'd radius the
transition rather than do it as two straight-line movements.

Another trick you might try is to lay a strip of thin packaging tape
across the transition between wedge and stock (the radiusing is only
needed right at the transition point).

Nah, you're wrong; taper looks better. IMO of course. :-)

How about sanding the edge of the plastic base plate on the router itself to
make the transition smoother whether going up or down.

Ask him if he would like some nice decorative burn marks. LOL.

If you need a good reason to help talk him out of tapers, altogether....
The idea behind fluted trim is to architecturally imitate Romam columns,
which are not tapered.
