Well, just to try & find it, I just opened another window awhile ago & went back 2000 posts plus & minus but I didn't find what I was looking for. I may have gone far enough one way or the other but yes, I like working with horn, I like the outcome so I try to keep the air moving. I think the trick to keep it from warping is to keep it cooled down. It was fun going back though to see our previous posts quite a ways back.:shrug:
