Topic tags/keywords: question bandsaw

Primarily, how long should they last? I seem to be cursed. I do a lot of resawing and it seems like as long as I appease the bandsaw gods by buying a new blade before I start a batch of resawing, it goes without a hitch. But if I take any sort of a break, whether to do a few quick non-resawing cuts, or in the most recent cases overnight to get some sleep, I come back to a bandsaw that refuses to track properly or cut at a reasonable speed. It works fine for cutting my now 1/4” boards into pieces of box, but as soon as I try to put anything thicker than an inch or so through it, it rebels. I’m guessing that it seems to happen this way because I don’t notice the gradual decline in performance as I’m working, and only become aware of it once I’m starting fresh, but it still seems odd that the blades are wearing out so quickly. These are good quality Timber Wolf blades and I feel like I ought to be able to get more than eight or ten hours of use out of them.

I have an expensive band saw and I have trouble with blades breaking easily also.

I think your problem is not haveing a dedicated blade for resawing. I had the same problem a few years agot ‘till I asked someone in the know.

He informed me that the blades are all computer cut and set, making all teeth consistently perfect with each other and blade. As soon as you use the blade for cutting anything other than a straight line the teeth configuration and blade change. This is enough to make the blade wonder when resawing. He suggested I keep the resaw blade for that purpose only, and use another blade for all other cuttings.

At fisrt I thought he was full of …., but I tried it and my problems went away.

I don’t use my bandsaw for anything other than straight lines. If I’m not resawing I’m cutting rectangles. And in this case there wasn’t even any non-resawing cutting, it went brand new blade – eight hours of resawing – sleeping overnight – wouldn’t resaw in the morning.

I’ve never really kept track of how many hours I put on a bandsaw blade but I am certain it is much more than 8 to 10 hours. I use a 3/4 inch blade on my 18 inch BS for resawing. I’ve had it for over a year and I have resawed 100s of linear feet of boards. Most are around 6 inches wide, but I have resawed 10 inch wide boards also (very slowly).

For what it is worth, I switched from a very small 11 inch BS to an 18 inch BS over a year ago. You talk about “refusing to track properly or cut at a reasonable speed”. Tracking was a real problem with the little BS and it is virtually no problem with the 18 inch. Regarding speed – BS cutting, especially resawing, is always a slow process. I would estimate that I take about 3 minutes to resaw a 2’ board of oak that is 6” wide. I just don’t rush it and I sort of let the saw set the pace.

Let me follow-up on my own post with this additional comment. I use the 3/4” blade only for resawing and other straight cutting. If I need to cut a curve I switch to a 1/4” blade.

I use a 1” carbide toothed blade for all resawing and 1/2” or less for curved cutting. The 24” bandsaw is pretty much dedicated for resawing and the blades lasts forever. The other two 14” saws are for curves and fine cutting. Carbide blades will really save you money in the long run.
