I have a Craftex cx104 "ultimate" 14" bandsaw (same as the grizzly circa 2014). Normally it works well... however two weeks ago the 3/8th" blade broke in use, so I replaced it.
Unfortunately the only 3/8th x 101" blade Windsor Plywood had in stock has 3 teeth per inch and is "quite aggressive" - nice when cutting a softwood but terrible when you're cutting something hard like Jatoba - two days ago I was holding a 6" long, 4" high, 1" thick piece edge down and cutting into the 4" side when a tooth caught, slamming the wood down forward. Not fun, so I got the 6 teeth per inch, 1/4" blade I knew Windsor had in stock.
It won't stay on - I've adjusted the guides and retensioned twice, but it persists in moving to the front of the top wheel and therefore out of the upper guides. The wheel alignment has not changed - when I put a 3/4" blade on it stays where it should, as did the 3/8th. So what am I missing? Does a narrower blade need different wheel alignment or tensioning?
