Topic tags/keywords: mahogany question

I have started building a box out of mahogany. This is the first time I have worked with this variety of wood. When I cut the miters for the corners, the wood chipped or split at the bottom of the cut 7 out of 8 times. I have used the same sled, blade and saw many times before on walnut, maple, sapele, etc. without encountering this problem. So my first question is: is this typical of mahogany in general or do I have a poor piece of lumber? The second question is: what can I do to reduce the tearout issues, given that I have a reasonably large board that I want to use for other projects instead of turning it into firewood. Comments and suggestions welcome.

A zero clearance insert will help. Can you be more specific about what kind of “Mahogany” you have? This is a word that is used to describe some very nice wood and several others, not so nice.

Paul, I am not sure what kind of mahogany it is. It was sold to me as “mahogany”. I think it may have been one of the “not so nice” types you mentioned. Thanks for your input.

zero clearance, backer board, blue painters tape – those are the techniques I know of to deal with tearouts.

personally I find mahogany to be very soft, and cuts cleanly – what type of mahogany are you using?

As shipwright says, a zero clearance insert will help. Otherwise, yo can put another piece of wood as a backstop at the exit of the cut to stop that. But that wastes a lot of pine.

As above, backer board and blue tape would be what I would try. If that didn’t solve it then I would try scoring it with a razor knife.
