Dragon Mike, the problem I had with some of the lumber yards, Home Depot, Lowe's, etc., is the quality of the boards, moisture content, and cost. Some of the so called untreated boards seem like they are treated. I guess low heat for drying wet boards! For some reason the boards in the dojangs are different... Has anyone dried wet boards in an oven before? Thanks for the web address Aodhan. We cut our boards to 1"x 12"X12" boards for adults/juniors 12"x6" for pee-wees; 1/2"x12"x12" for junior demo from the lumber yards. The 1/2" are more expensive. Our Home Depot charges after so many cuts! Amazing isn't it! Hey, time is $$$! LOL! But, I did get that look that you're talking about, Iceman! I had to perform hand breaks during a demo and it was during the summer and it was hot, humid and raining outside. The doors were open to the gym and I tell you, those boards were EVIL!!
