High angle planes (60 degrees), with a high speed steel blade will allow you to work dense tropical woods without tearout. They are specialist items though, and are pretty expensive. You also have to know how to sharpen, and have appropriate sharpening stones.
Unfortunately you either have to buy expensive powertools or handtools, or work at a snails pace, with what you already have. Its not a bad idea if its your first couple of bows as slow work gives you time to learn and digest the process. Rushing is a bad idea when learning.
