I'm currently working with a lot of shedua (here we call it ovangkol) and I'm seeing a lot of tearout when jointing/planing the stock.

I know that the grain is interlocked, but I get a lot of tearout even if I take off as little as 1/10th of a milimeter.

My jointer/planer is a Hammer A3-31 and the tables are properly aligned, the knives are brand new (and self-adjusting) and I'm using a very slow feed rate (by hand) when jointing.

Still I get tearout...

Can I do anything to avoid this or is there no other alternative than to either hand plane it after glue-up or take the glued-up panels to a wide drum sander in a local cabinet shop?
