   blade, tension, etc.

   Sounds like the blade might be dull, perhaps combined with improper tension and/or too fast a feed rate. What's the TPI of the blade being used? The usual suggestion for resawing is 3TPI.

   also worn guides, alignment of the blade to table. height of guides. sometimes you have to feed it at a slight  angle to the blade and follow your cutting line

   Bowing in the center is usually caused by not enough tenison... the symtom of drifting off-line is usually caused by a dull blade or one that a tooth is knocked out of set but combinations of the three can happen.

   Good luck...

   Well thank you all for the help.  This was my first post.  Next time I'll try to answer all of you in one response.  Gotta give the new guy some slack, I guess.  I appreciate all the suggestions, and I will follow up when I get the new blade.  Does anyone resharpen bandsaw blades these days?

   Thanks, I'm going to re-check the guides and tension also.

   I live about 25 miles from Highland and used to use Woodslicers. They don't stay sharp that long and once a blade is dull..it's dull and won't cut. But.. add to that the fact your FIL used the BS and the insert is chewed up. If he didn't have enough tension and the blade was flopping around more or less chewing up the insert.. it very well may have knocked a tooth or teeth out of set. I was installing a new Woodslicer once and banged a blade tooth against that table rather violently getting it on the wheelws. Knocked a tooth or teeth out of set and the blade simply bowed inside stock from the git-go. I pulled it off and trashed it regardless of the fact it was new.

   Dull is dull.. tooth knocked out of set is a tooth knocked out of set.. Neither will perform properly and the sooner you realize that the better off you will be!

   Good luck...

   I asked a dentist once what it would cost to put braces on my bandsaw blade's teeth. His quote was "just a little" more than the cost of a new blade.

   I also considered getting my own setting and sharpening rig, but decided it was cheaper to leave that to the pros.

   I agree about doing your own sharpening on BS blades. Cheaper just to buy and I keep a dediecated on the 18" & 14" with a spare hanging on the wall to avoid down-time. But.. with that said I personally believe that few too many don't bother to clean resin build up from teeth and gullets on BS blades. If you work with a lot of softwood which I don't.. especially so but I do watch my BS blades and clean them when I see any resin starting to build.
