I have a library job to do that is going in a round room. I was able to create the parts for the casework but I would like to machine the crown out of solid stock on the CNC to conform to the casework.
Is anyone out there fluent enough to be able to create this for me?
On caveat, all of the bookcases have finished ends and I would like to machine the crown with the 90° return rather than making the piece long and field cutting the curved piece on site.
If anyone wants to take this on drop me a message.
The curved crown will have to match the straight crown. I have done this, it isn't really too hard if you have the equipment.
I lay up the solid stock, cut it with my CNC to match the shape and run it through my Micron molder. I also have a Weinig molder, so I use the same knife to run both the straight and curved crown. If the crown is an outside curve, that can present some issues.
Just for reference, I charge a $1,000 per arched crown. Also, plan on cutting the miter on site and make the crown long.
When I think of a Library, curved crown, in a home, I think wood and more wood. If you visit my web site, we show a library with a curved wall, curved crown and everything that goes with it. We got about $90,000 for that room and that was 10 years ago. There is no way I could possible do that room or any library I can think of without woodworking equipment.
If there are wood moldings etc in your library and you are going to do the job, I would suggest you partner up with a local millwork shop. Also, most millwork shops do not do finishing and if you do find a shop you can work with, make your decision based on the quality of their product, not price. You can burn through a lot of time and money sanding poor quality moldings.
If you do not know how to judge the quality of the moldings, hold the molding up, pointing it toward a light in the ceiling and look at the cut. Chatter, etc will jump out at you. Another thing you can do is to close your eyes and run you hand along the molding. With your eyes closed, your feel will be more sensitive and you will feel the chatter etc.
I can and have done curved Crown on my CNC with a 2 rail sweep file in 3d. if you have and use a program capable then you can do this. it has been a few years for me as we went all commercial in 2010. It is fun to learn yet easier to outsource if you are not set up to do radius crown, (IE a marcon type moulder) the question is how much how often will you do this. Sell one job, then if you get another consider the machinery. Below is a 24" diameter file i did some years ago
I have gotten by just fine in the past 20 years with the equipment that I have in the area I live.
I had quite a bit of equipment until a health issue caused me to close my shop a few years back. I was able to recover to the point where I am getting back on my feet but can't do it all right away due to the cost of that situation.
A builder that I have worked for for years needs this project done as the guy they originally hired walked away and left them high and dry.
I have a CNC which is perfectly capable of doing what I am looking to do, I just do very little if this type of thing so I am looking to outsource the programming part to someone who may have more experience in doing it so I can focus on the rest of the things I am doing.
If there is nobody who wants to do this I will have walzcraft do it. But first I want to check to see if anyone wants to give it a go.

WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.
Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).
Libel: Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.
Improper Decorum: Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).
Advertising: The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).
Repeated Forum Abuse:
Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.
There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
