Oooohhhhhhhhhh FAIL...Twice on the same bow
I laid the bow out for 64" with 2" wide pyramid to 1/2" tip limbs. The backing was .075 (maybe too thin being the issue). I trimmed the bow to the pyramid width and the thickness (.475ish). Then I rounded the corners everywhere. It bent pretty good so I long stringed it and started exercising it a little at 6" and 15 lbs. I got to about 25 count and stopped and decided to look it over good. Found a few rough spots and got out the sanding block. While sanding it, a splinter caught the sandpaper. Deep and wide no chance of gluing it because a piece of sand paper stayed deep into the crack. It was about halfway up the limb and looked to be all the way through the backing. So I let it sit overnight for me to cool off a bit... I looked it over and decided if I relaid out the bow I could trim the crack out of it. I trimmed it out and the bow was now 1 1/4" wide instead of the two inches originally planned. I also made it 4" shorter. I thought well I could just make it a kids bow. So I continued, rounding, sanding. I went back to the tillering tree and started exercising it again. At about 25 pulls to 6" and 10lbs. CRACK............ other limb crack through the backing again..
Do you think .075 is a bit thin for White Oak??
