   I don't see how this is possible. Crown fits the ceiling diagonally, so the lower portion will have a shorter distance to cover than the upper portion. This is like trying to stretch the crown.

   My suggestion would be to make your own crown out of multiple pieces. First attach, say, a 1X3 flat to the vertical wall (with the 3" portion vertical). Then attach a 1X1 to the top of that piece. Between the two attach a 3/4 inch cove molding. Finally, attach a 1/2" cove molding to the top piece. Or, some variation of this that "looks right". If you're up to it, you can make your own pieces in the profiles you like and put them together to get that "special look".

   Are you trying to wrap the crown around a structure like (but of larger radius) a pillar?I have no experience with shapers, but there are many here that do. Could you use a crown molding cutter on a curved piece of stock?Do you have a mill nearby? Call them and ask...I saw an episode of This Old House where they made "plaster" crown molding. It makes me wonder, can you purchase crown molding made out of a synthetic material like foam then bend it and paint it (you didn't say if the crown molding was painted or stained.)Just a few ideas.

   Measure it with a micrometer, mark it with chalk, cut it with an ax.

   I don't see how this is possible. ...

   I never tried but a carpenter I saw long ago in my GrandPa's house was puttin' up Crown molding... As I remember he hand cut 'curfs' ? in the back to put it around PaPa's curved plaster walls in the corners..

   I don't have the patience fer that!

   The only possible way to do this is to slice the crown into strips on a bandsaw. With careful placement of the saw kerf you can hide most lines. Of course trying to hang the crown will most likely require some help.

   I have run into this before. My research turned up "flex moulding" I didnt get the job as my bid was not low, so I didnt have to install it. You may see them at    http://www.flexiblemoulding.com   Good luck  Bob

   I worked with that stuff a few times.  It's not bad, but odd to work with.  It's like cutting and nailing a very thick rubber band.

   I do this all the time at work.

   You got access to a shaper and the proper cutters? If so build up your red oak and run it through the shaper with a fence that has a radius of 25' 6".

   Well theres more to it than that but not going into it if you don't have the necessary tools.

   If you don't have access expect to pay dearly for someone to do it. I think we get in the neighborhood of $100 a linear foot for average size crown.

   Curved moldings used to be done with plaster.

   Moldings like to take a path of least resistance. For crown, that is flipping onto its back.

   One good way if you don't have big equipment, is to use the brick-lay method where you assemble segment of the parts where you stagger the joints between layers. You would start with arced parts with the cove cut on it, followed by the next layer with the lower portion of the ogee, then the middle then on up.

   i'd imagine glueing up enough oak to handle a 25'6" radius (length of arc unknown) would be a job in it's self.  then to make a fence with a matching radius for the shaper.

   it would be at least a 2 man or 3 man job to feed it into the shaper and then back out.

   williams and hussey makes a moulder that will do arcs, ellipses, and circles, but very pricey when you get all the bells and whistles.  but i'm sure you'd have to laminate a lot of stock together too.

   i'm thinking the flexmould route would be the easiest, then just faux paint it to look like oak.  kinda like the graining they do on fiberglass and steel entry doors.

   or just go with all painted crown.

   be glad you weren't the low bidder on that job.  i don't think that guy knows what he is really getting into.
