If I run into curves, like bull-nosed drywall corners, when installing crown molding, I make my own "profile knife" out of a drywall knife and run plaster around the curve to match the
wooden crown. Here is an article I wrote with the details: http://www.finehomebuilding.com/how-to/depar...
The same techniques used to make these curved crown corners can be used to repair or replace damaged or missing paint-grade moldings. This is especially helpful for old homes if the profiles are not readily available. Custom millwork runs for small batches can be prohibitively expensive. So, making a profile knife and using plaster can be a good option.
I collected plastic pots of different shapes and sizes, cut the bottoms off, slit them up one side and taped the slit back together. filled them with concrete and then removed the pot by
removing the tape after they dried 24 hours. They are still a bit damp so you can do "wet carving" on them to make your forms more rounded or smoothe. I used rebar again as I had with the Polatems in my earlier post, or you could use conduit, and make them into lanterns. Be sure to put a hole in the middle of each piece so you can fit them over the rebar/conduit. The circular pieces I made by just rolling in my hands...other pieces can also be made such as a finial for the top, which I have yet to make and put on the top.
This bathroom remodel was done a little while ago but I still think it's one of our best - mainly because of the bay window which gives such a great focus to the space. Actually the bath
was in the window location in the previous design, but we moved the position slightly so that we could add the beautiful walk in shower. I also think the wash basins and vanity set on the corner works well. You can see more photos at http://rule4remodelingcontractor.com/bathroo...
