Topic tags/keywords: ebony chipping

I am working on a jewelry box with an inlaid design. I am having a problem cutting triangles from 1/8” thick ebony. I have tried taping the edges and providing support for the cuts with a piece of hardwood in front of the miter.
I can make the 90 degree cuts just fine, but cutting the hypotenuse is a problem. I’ve made 4 cuts and 3 of them have chipped.

Any help would be very much appreciated.

Try sandwiching the piece between scrap or scribing the cut line with a utility knife.

Robert, Thanks very much! I sandwiched the piece as you suggested and my success rate improved dramatically! I really appreciate your help.

Sandwiching also helps to prevent blowout from the backside of a piece of wood when drilling a hole.

Another technique… select a very fine saw blade.. There are blades that are special for plywood and that would do the job….

I would also consider making the hypotenuse parallel to the grain – that way the 2 acute angles would be much less likely to chip out and the 90 degree angle would be the only cross grain cut you have to deal with and since it isn’t acute, it will be stronger.

All really good suggestions. I’ve got a couple of more pieces I have to cut this week, and I’ll give some of these a try. Thanks!
