I have a 14 inch Delta and until I spent what seemed like weeks learning to tune it and tension the blade exactly, I could get no acceptable results from it. I've also installed the Carter guides, which helped only a little while introducing another variable. The biggest problem is determining exactly what part of the blade should ride on the crown of the wheel. You can't make any other adjustment until that is set exactly right, and it varies somewhat by blade type and width. I also have a fairly well tuned 9 inch delta band saw with conventional guides that I use pretty much for cutting tight curves with no more than a 3/16th blade. It isn't perfect, but with proper tension, slow cutting and paying extremely close attention, I can get a pretty accurate cut. It is much harder, for some reason, to get the blade 90 degrees to the table on the smaller saw (I use a pixley or engineers square for this). Change the blade, alter, release or reset the tension or fail to occasionally clean the tires and things go off enough to be noticeable. So, after all this, I'm not really sure a cheap band saw will even do box making. Just sharing what has been an annoying and frustrating experience for me because I'd also like to do band saw boxes. So I'm looking forward to following this string.
