Hello, The shape of the scorper is the critical feature. Everything you need to see is in the video.

That’s pretty awesome. I could get lost in that guy’s channel too.

Pretty remarkable. Or I could sell you both of mine for $25 each:

The first time I clicked it showed him making the drill, second time the circle cutter - would make a great rosette, you're right.

Re: The scorper, a rosette channel cutter
I love his channel. I saw that video too and wonder if spruce is too soft and the grain changing relative to the path of the blade might make this problematic.

Re: The scorper, a rosette channel cutter
Bryan,
One way to deal with that would be to make the scorper with cutting edges on both ends. One would be as in the video. The other end would be modified by hollowing out the center of the edge with a file to form two spurs on the outer edges. The cut would be started with the modified end to score the surface and cut down a little bit, and then finish the bottom with the straight edge.

Re: The scorper, a rosette channel cutter
Funny you should say that Bob. I am in the process of making a new circle cutter for rosettes. My plan was to have the cutter und be spear shaped with bevels on one side only. You would use the bevel side towards the waste side by turning the cutter around depending on if you are doing an inside or outside cut. The other end of the cutter is ground like a scraper so you can flip the cutter over and scrape out the material between the edge cuts.
Perhaps I should look into making an iron that is the same width of my purfling that I can sharpen as you describe. My worry is that it will get narrower as it is sharpened and flattened. After a while it would not match the width of the purfling anymore.

Re: The scorper, a rosette channel cutter
Look carefully at the cross-sectional shape of his cutter. It's feathered for clearance on both sides.
