How to match mis-matched crown moulding

Hello DIYers. I'd like help with my crown moulding, please. We had custom moulding installed (3 years ago!) between our kitchen cabinets and ceiling. The installer left each end cut at the 45 so we could continue the installation around the room. Unfortunately, the millwork was custom and we can only find a moulding that is similar. I though of adding a corner block and then starting with a new piece, but the end isn't cut square so it doesn't touch the block. I thought of adding a little piece of moulding to bring it square and then cope in the next piece, but I don't have enough scrap to do both ends. I don't want to take down the moulding that is there as it all nailed and caulked into the cabinetry and I don't want to damage it. Any suggestions?

At the same time, I may as well ask. The house is 160 years old and no where near level. Any hints on easy ways to get the crown level when the walls and ceilings are out?

Welcome to the forum.

I’d try to contact the installer or the company he worked for to find out where they get their crown so you can get a match.

There are many threads on this site on installing crown. Do a search on this site to find them. You can always come back with questions if you don’t find the info you need.

a lot of the smaller millwork shops that make their own moldings will grind a knife to match anything you have. You would just need a small piece for them to make a template off of. They will charge a fee for grinding a knife, usually less then $100. They may also charge a small setup fee for making a small molding run. I have done this on occasion to match moldings in old houses.

Thanks! I do have a 5" piece that they could copy. Mike, just so I know what to ask for at the shop. Knife = router bit or something else?

knife is a router bit on a high speed commercial machine. a good shop will have a computer program that will scan the profile and cut the blade. used to be we would grind our own blades by hand doing trial and error. the shape of the blade has to be ground to the angle of the blade as the wood passes by on the rail of the machine, not at a 90 degree to the wood. It is really another dying art, i got pretty good at it but was many moons ago. And it takes 2-4 knives per head on the cutter
The older I get the better I was

Making new blades off a piece of scrap is quick and easy for a big outfit. Bring it in and have them make it for you. It may not be cheap, but if you plan to do the rest of the house, buy it up front now. Let the wood sit inside for a while before installing it, and then if you ever need to end it before redoing another room, try and get it to end flush against an inside wall, and simple cope the next piece in when the time comes.
