Crown support blocks

Mike Fuson

Here recently Iíve had to install some crown molding by myself so I came up with these little jigs to help hold it in place. These things might be a common thing that are used but Iíve never seen any. I was going to use knob bolts but the ones I had wasnít long enough so I used regular bolts with a socket driver in the impact drill. I used t-nuts in the back with some extra screws to make sure they didnít pop out. I put a cleat on the inside to hold it to the correct height, plus another on the outside for an extra large ledge. Snugged up and about two ďclicksĒ with the impact makes it where they wonít budge and it doesnít hurt the cabinet. Anyway, Iíve only used them on this one job and they were a great help to me, wished I had thought of it years ago. I thought someone else that has had the same issues might want to make some or give them an idea for their own version.

Fastcap makes these but I never got around to trying them so I'm not endorsing them.

Pat, Those look a lot like the brackets used to support a plank while roofing. Seems like they would be much better in a thinner material? Sheet steel?

Nice idea. We always have cabinet screws on the job for clamping face frames and we just use those. They don't have the handy stop though but the cabinet screws make installing crown a lot easier.

Mike why wouldn't they work on cabinets?

Pat i use these when installing crown in a room (lets say 12 feet long) when I'm alone their just a helping hand. The crown flops around in them and doesn't hold it to an exact line and their not meant to be. The jig the OP made rests the crown on an exact spot measured up from the rail while the red ones will need to put a screw at least 3 inches or more up from the bottom of the crown and are really only useful as a third hand at the other end. Before i bought these i used a coat hanger and a screw to do the same thing. The crown will fall to the forward angle which is not correct for crown so their will be a twist going down the length of the molding but that doesn't matter so much as you work your way across the wall the hangers slip out leaving the screw hidden behind the crown. On an average size room i use only 2 one on the end and one in the middle.
I guess a more direct answer to your question is the rail is not tall enough for the screw needed to hold the hanger.

Great idea. I always just use a strip of wood the width of my reveal between door tops and moulding bottom and clamp in place with a couple of spring clamps.

  • 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.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.

  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • 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.
