After avoiding yellow birch for the last year because of constant tear out with handplanes, I got a deal this afternoon on some cheap 8/4 birch that will be used for my upcoming roubo bench build. Well I did have again some nasty tear out when I pulled out my veritas low angle jack and low angle jointer. The jack blade has a microbevel of about 30 degres for a total of 42 and the jointer is probably the same. That's eyeballing as I sharpen freehanded. What I don't understand is that I got no tear out when I dimensioned the wood with my dewalt 13" planer. Why can't I achieve the same result with handplanes on that fricking birch ? I'm done with birch otherwise, it's a real pain to deal with and it sucks because it's quite beautiful and cheap around here.
