I have the little 10” Craftsman bandsaw, it’s my first bandsaw, and my main bandsaw interest has become resawing. Now, before everyone jumps up at once and tells me to get at least a 14” saw, I’m working on that, but for now I want to solve the problem for my current saw if I can. 1) brute force may win, but the same misuses of tool will just limit me on a 14” saw. 2) I’m experimenting with smaller projects and various more expensive woods so the 4.5” resaw capacity is just fine, for now.
At the suggestion of a forum member, I bought the woodslicer blade at the same time as the saw. My last project, a small bookshelf made from a foot of 8/4 jungle walnut far exceeded my expectations. I ripped and resawed off a few solid, routed pieces, and then cut the rest into 6 slices of veneer about 1/16th think. The veneer slices were uniformly thick and just needed a little sanding. I was so happy with how the raw pieces turned out that when that was finished, I ran out and bought some other woods.
The first was Padauk. I prepared my slices, and went to resaw, and total fail. I spent all evening tuning the saw and trying different things, and I got 1 or 2 good slices and just about ruined the rest. The main symptom was that even after compensating for blade drift, where the back of the fence moved sharply to the right, the blade wanted to go right into the fence within a half inch of cutting, suggesting the fence need to be moved even farther right, but that was just getting impractical. I even tried resawing some pine and it couldn’t even do that right. Defeated, I ordered another woodslicer to rule out the blade itself being the issue.
Finally I had time to test today, and sure enough, the new woodslicer works fantastic. My first drift calculation was off a little, but a minor fence adjustment and test piece of pine looked like it had been cut with a laser. I salvaged what I could of the Padauk and it all went as expected.
What’s disturbing is it seems like I barely used that blade. So I’m trying to figure out, what did I do wrong? a 35$ blade for every project or two is going to get expensive. So I will disclose everything I did with the blade, and maybe some of you experts have some ideas on where I went wrong.
I can’t believe I had more than a half hour of continuous cutting time on the saw. I did resaw a firewood log of some kind of hardwood, I think almond, and cut that into about 9 slices and that was pretty dicey and I wondered if that was hard on the saw given learning to control a bulky log through it went with some horrible noises and stalls. But it was one log only. And then I’ve used it here and there for cutting 3/4 inch plywood and pine for various projects where rough-cut is ok. Some of that was cutting curves, and the woodslicer is not meant for curves, but again, I wasn’t doing it for hours on end. The plywood may be no good either without carbide, but let’s say that was 10-15 minutes max of continuous cutting.
So what are the possibilities for blade defects?
- is the blade just dull because of the way I’ve used it?
- is it maybe just dirty, and worth cleaning and trying again? No doubt I’ll at least try this.
- Did I bend it or deform it somehow? It doesn’t sound horrible running on the saw but I admit the new blade is quieter.
Something else that seems to be true as well. It seems like I had a bit of an issue adjusting the tracking on the “old” blade. It wanted to creep to one side or the other even when spinning the wheel with my finger and it took a while to get it to stay centered. With the new blade, it was just a couple of turns to move it inward and it seems fine.
Any comments on my scenario or general tips on bandsaw blade life appreciated. Before buying another woodslicer, I nearly went for the Lennox Tri-master, but decided to keep the test consistent. I’m thinking the tri-master will be the next blade, but, if I’m doing something wrong that’s shortening the life of a 35$ blade, don’t want to just continue that with a 100$ blade.
