Gene Howe Posted April 1, 2022 Report Share Posted April 1, 2022 Is there a chart or spread sheet for angles relative to wood thickness for inlay work? I've seen a video of cutting circles with increased angles. Is that what I should do for each of the different usually used thicknesses? Thanks.

John B Posted April 1, 2022 Report Share Posted April 1, 2022 I just cut a keyhole shape into the edge of a piece of timber the same thickness that I'm going to use and adjust a few times until it wedges where I want it to.

Dan Posted April 1, 2022 Report Share Posted April 1, 2022 I'm not sure if there's a table but you also should include blade thickness into the formula. I went back to high school geometry to determine thickness with some success. Grab some scraps of wood and do a few tests to determine the angle that works for your project.

That will save a lot of time and create a great start point. Experimentation still a necessity but this will save headaches. danny 1 Quote Link to comment Share on other sites More sharing options...
Dave Monk Posted April 1, 2022 Report Share Posted April 1, 2022 I mainly use two pieces of wood that are .4 thick. Using a #5 blade I am setting my saw at about a 1.6 degree angle. I would imagine that can vary with saw blade brand also. I have never had any luck inlaying thicker wood. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
timelett Posted April 1, 2022 Report Share Posted April 1, 2022 I'm relieved to see others who are struggling with inlay, being new with scroll sawing I thought it was just me. Especially thick wood, it shur is pretty cool when you know the way to do it. danny and OCtoolguy 2 Quote Link to comment Share on other sites More sharing options...

Rolf Posted April 1, 2022 Report Share Posted April 1, 2022 (edited) Take your time when cutting inlays and make sure not to push sideways. These were 1/4 into 1/4 inch material.

John B Posted April 2, 2022 Report Share Posted April 2, 2022 Another thing to consider when cutting inlays is the direction in which you cut. Because of the angle of the cut, a very sharp (pointed) turn can try and force the blade to cut across itself. I don't think I am explaining this very well, but if you set the blade at an angle and try and cut a sharp point in one direction, then the other, you will see what I mean.

Olson 2/0 R 28 TPI Very nice Rolf. I have a dozen of each of these type of hinges, circular and rectangle. Have had them in a box for years, just never got around to using them.

The box designs are John A. Nelson with some modifications by me. I bought the hinges from https://www.nationalartcraft.com/product-index.asp I don't think the rectangular ones are available any more. I stopped making them as they wasted a lot of wood. Having said that, I still have some of the hinges and should use them up. This was my collection. meflick, John B and OCtoolguy 2 1 Quote Link to comment Share on other sites More sharing options...
Sycamore67 Posted April 2, 2022 Report Share Posted April 2, 2022 (edited) This is an interesting question and discussion. Rolf's graph is helpful. I do have a question about the graph. I think the width of the kerf is the important variable rather than the blade thickness. I have tried measuring the kerf and found it always to be a bit more than the blade. I measured kerf by taking a piece of wood about 2" long, cutting in two and remeasuring it. For anyone with a calculator---- I think that the angle equals the inverse sin of the kerf divided by board thickness.

Unfortunately, 63 years have passed since the last time I used that sort of math so I'll just have to take your word for it. Lol.

Also the quality and adjustments of a saw also impact the kerf. John B, OCtoolguy and NC Scroller 2 1 Quote Link to comment Share on other sites More sharing options...
