Curved Ranged Hood

11/9/21       
Peter Member

Hey guys,

I've got an interesting hood to build for a customer and I was just trying to see if anybody had any better ideas than me ..

Where I'm at range hoods must have an access to the piping for inspection (i.e. no solid front), until now I have been solving this by making a door in the shape of the hood as the "front panel" that operates on hinges or is wedged into place by some kind of trim. Because of this reason we try to stay away from doing hoods that are curved on three sides, but of course that's the hood I need to build now.

I can't come up with a good way to make a curved front panel removable without having a terrible joint where the three curves come together, and I have to mount the curved portion to a cabinet box that will support it.. I was thinking I could make the three curved section separate from the box part of it, but I'm not sure how that's going to look when it's trimmed out, etc.

Any ideas?

I've attached a picture of the version I have on my plans.. it doesn't reflect the curved part but where it's angled it will be curved.

Perhaps you can get the appliance guys to preattach the piping to he blower and then push the whole assembly up through the ceiling to the attic space.

Then you make the final connection there with plenty of room to work. Flue then through roof, done.

Has worked for me in the past.

Are you thining Arch or curve ? We use Star hangers to snap any panel on flush which needs or not to be removeable. next week i am using them to attach my cushions on my sailboat which i am convinced is far better than snaps or velcro.

Ask about the new gemini system, Kip Porter (Founder of Southern Architectural Waoodwork, For those who remember that far back) Kip's a genious who intends to set the new standard in fastening from his experience. I do many of his prototypes and am convinced he is spot on with the best there is in fastening.

Could you cut a hole in the cabinet next to the hood with a removable access panel to inspect the pipe? Or a small hole and inspect it with a small flexible inspection camera.

I would think it would be fairly easy to make the curved section removable and make a little frame that it attaches to that stays on the box cabinet using neo magnets or something similar. Then you can trim out the entire curved portion and make it part of the removable section. We have done similar before. We have also made inspection panels on either side of the fan units. Good luck man.

I’m not sure how relevant this is, but I built one recently that was similar except free-standing on the wall. The installers had to play around with the piping to be able to push it up and have it connect, I also remember the blower motor coming out so they could reach up through the pipe.

I’ve also heard of using flex duct, which is not ideal but would work.

I would agree that it should be accessible if possible, but I’m not sure of the legitimacy of that as a code issue as there are stainless hoods that accept the liners that are definitely not accessible.

The issue here is getting the piping inspected by the hvc building inspector. Try telling him to look through a hole or use a camera and he will tell you to just take it down or he won’t sign off.
No flex hose is allowed on vent hoods. They have gotten lot stricter lately

  • 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.
  • Subject lines may be edited for length and clarity.
  • "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.
