    cutting a curved rebate

    Hi. I'd like to make an elliptical frame for a piece of glass that will be the top of a coffee table. The glass would fit into a rebate cut into the inside edge of the frame. I could cut that rebate with a router, but I'd prefer to do it by hand. This would be like cutting the ledge for edge banding on a guitar, only much larger. If folks could recommend a technique for doing this I'd appreciate it. It needs to come out very clean as it will show. Thanks. -Howard

    Circular Rebate

    I use the item pictured. You can make the radius anything you like. I first establish the rebate edges with a wheel marking gauge and use the tool to remove waste by starting very shallow and tapping the chisel in a bit at a time.
    Sorry but I cannot upload pictures. When I figure it out I will post them.
    ANyone have any help on uploading pictures from my desktop?

    Howard, I cut a curved rebate in my seat, and then used carving gouges to remove the waste. The line for the rebate was marked with a marking gauge that has two roller guides that follow a curve easily, as opposed to a typical marking gauge that has a straight fence.

    Phil, it is the Newkiton marking gauge I got on Amazon..I think it is a Chinese tool but it does the job for me. I just checked Amazon & it is not currently available. I was surprised that there were no quality marking gauges on the market that handled curves…Woodjoy made one in the past but I believe he shut down. I think Chris Schwartz has instructions to modify a standard gauge.

    You may be able to use a stringing cutter or the fence for a router plane.

    Actually my understanding is members may be able to post images, they have to be contributors to see images that are hosted on SMC's servers.

    Sorry but I cannot upload pictures. When I figure it out I will post them.
    ANyone have any help on uploadi
    If one is replying to a thread, above the text entry area is a banner with small icons. One of them looks like a frame with a tree in it. Click on this and it will offer the option of posting an image from your computer or a URL.

    If the REPLY button is clicked twice, it will have another banner above with a paper clip. This is for adding attachments such as images. Hint: if more than one image is to be uploaded click on the + before selecting images.

    Usually my response to questions of posting images includes images of the icons.

    Since Michael is not a Contributor images wouldn't appear on his screen.

    An off the wall just hit me. Would it be possible to cut cleanly inside of the ellipse and drop the cut piece down for the thickness of the glass to create a ledge (rebate/rabbet)?

    Strange minds have strange thoughts.
