Planing purpleheart.
I recently bought a purpleheart board. I have never worked with it before but the first thing that struck me is how heavy and hard it is.
When I ran it through the planer it seemed to chip a lot. The planer knives are sharp and I took very shallow passes but it still chipped up. Is this a normal characteristic of purpleheart, and is there something I can do to minimize it? I have no idea of the moisture content of the board but is it possible that it is too dry? My planer seemed to have no problem with 13 inch wide curly maple, but it don't seem to like this 6 inch purpleheart board.
Any ideas would be appreciated. Thanks
Wayne.

Hi Wayne, sounds as though it is picking up the grain and tearing it out. could only suggest end for ending the board and running it through and see what happens.

Ah yes, purpleheart. Trust it to chip out when you run it one direction and chip out elsewhere when you reverse it. Alex has a good tip and you cannot take too light a cut. Wait until you run it past a roundover bit on the router table.
But it is beautiful when finished, so just plan to sand until it hurts.Cheers,
Bob

That's exactly what happened to me. Chipped in either direction.
Thanks for the suggestion Alex. I had thought of misting it with water but I didn't know if that would work because I never heard of anyone trying it before. I'll definitely give it a try.
I'm thinking of just planing it close to size then go to the cabinet shop where I used to work and run it through the thickness sander. If my old boss will let me as I work for his competition now.
Thanks for the suggestions.

Send it through the thicknesser on a slight skew. Works for me with other angry and uncooperative pieces of wood..
