Coped crown on all 4 corners in a closed room

1/28/24       
Mike

I don't know why this is racking my brain, but I have a room to install crown in that is 10 x 13 and it is an enclosed bedroom so all four sides would need to be coped. How would you guys do this or, would you make your last corner joint a miter? If I cope all four corners, in theory, I would be either coping every single left side and then the next molding would B slipped in behind the piece I just nailed up and that would go for every single piece except for the last one. On the first piece, I wouldn't nail the last trailing say 3 feet of it so I can pull it off the wall, slide my molding to the wall behind it and then snap in the ceded and into it.

The other option would be to do a right cope if I'm doing all left copes, so the last cope would be a left and a right cope. I'm using a Copemaster machine and I really don't want to go through making a template for just one right cope. I'm also too lazy to do it by hand. Lol

Am I not thinking about this correctly? I used to miter all of my corners and this would be the first time I have had to and or planned on coping every single corner on an enclosed room. What are your guys thoughts about doing this and how do you handle this? Thanks in advance

Cope your four pieces ahead of time on the bench, cut a small 12" piece and work the first corner, don't nail within 18" of the cope, go to the second coped corner , work the room until your back to the first corner, pull out the 12" piece, slide the straight end into the coped core and bounce the piece to the wall.

My approach is a little different
On the two shortest walls I cut then full length, then partially miter the lower portion to just above the cove profile of a typical crown
On the
two long walls, I miter them all the way through, just fat of full length, then cope only the upper portion of the crown, slightly undercutting right at the profile
Install the two short walls closely to the install height, nailing no closer than 12-18 inches from the corner
Spring the two long walls in, aligning the bottom edge of the mouldings, and push the crown to install height in the middle
The crown will almost self install using the above method, and have the appearance of being crisply mitered at the bottom, and frog hair tight on the upper coped portion.
If necessary, you can tap the crown up to tighten the joint, placing a driving block across both pieces to drive them evenly.
Goes a lot quicker than it sounds in practice

Thats not too big a room, shouldnt take too long.
I mostly cut and cope all four wals on the bench first.
For me, the wall that has the door you enter the room through is the last one the crown is applied to. First is opposite the door, square cut both ends, and like the others suggest, dont nail the last 18-24 inches.
Then, one right cope, square cut other end
One left cope, square cut the other end
Then the last piece, cope both ends
Like its been said, you can tap the joints up or down to tighten the joints if needed
To cut the lengths, the dimension the wall measures is the long point of the mitre for the copes
I do all my coping with a coping saw, touch up with half round and rat tail files as needed. I have a collins coping foot for my jig saw, and all the discs for the angle grinder etc,, etc, coping saw still the most accurate and quickest for me and I dont fall behind others
If you're too lazy to cut copes by hand or cant learn to do it well, maybe you should get someone else to do it.......

Just cope both ends of your last piece. Don't be so lazy. LOL

I agree with Adam. First piece goes up straight cut on both ends. Second and third go up coped on the end that meets the first wall. Last piece goes up coped on both ends.

Or, same net result, first piece square both ends. 2nd piece copes to first with square cut other end. 3rd piece copes to 2nd with square cut other end. 4th piece coped both ends.

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.

  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

    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).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
