I have turned a few pens and and letter openers. But not anything to write home about yet. I watched a few yt videos on bowl turning and thought i would give it a try. I took a piece of cedar lumber and made a nice little bowl out of a 4" piece of 2x4, so i thought what the heck woodcraft has a four piece bowl blank package for $29.99. I got the first blank cut on the band saw and mounted on a faceplate. After getting the outside to the shape i wanted and sanded down smooth i flipped it over on the tennon and when i started hollowing it out the wood started to crack in multiple locations. Just wondering if i did something wrong. How are you supposed to use these blanks with wax covering them?
