    Proof!

    Hey, folks,

    There are those who don't believe me when I say I'm the world's biggest doofus. For those few remaining doubters, I offer the following incident as definitive proof!

    So there I am, on a fine saturday morning. I've got big plans for the day of woodworking, but first I need to straighten up the shop. One of the big impediments is numerous large chunks of wood on the floor. Ok, have to process them sometime for the lathe, might as well do them all and get it over with.

    So I get a few done, but it's a little slow. So I tell myself ok, try the 3/4" blade. That way I can slice the corners off, turn them all into octagons, and then go back to the smaller blade for final rounding. How long can it take to change the blade? Five, ten minutes?

    I change the blade to a 3/4" timberwolf, just to see. Well, what I found is that 14" bandsaws just aren't designed to properly tension a 3/4" blade of that type, even if they *are* named 'Ultimate'. It wasn't cutting straight, so I made it a little tighter. It got better, better... just another turn... and then snap!

    At first I thought I'd broken the blade. When the dust settled, I discovered two things had happened at once: first, I'd twisted the knob off the tensioning bolt. Broke off right in my hand. Well, both hands... I was turning it pretty hard. Second, there are two steel bars that hold the tensioning mechanism in place... those both bent completely, and need replacement.

    Best of all, I actually rethreaded the nut that holds the long tensioning bolt to the mechanism. Had to put it in the vise to even get it part way off... far enough to get a hacksaw onto the bolt. Of course, to get it that far apart I had to take the upper wheel off, and the upper wheel guard, which also meant both front and rear blade guards, which also meant...

    Long story short, I've got a bandsaw that looks like it's been guillotined, with a bunch of parts to order, and a bunch of other parts lying about, and a shop still littered with potential blanks, and some cabinets still unmade, and Doorlink saying "I can't believe you're that strong!" and talking about getting at least one more, and maybe two more, husbands...

    So, Now do you believe me? Sheesh!

    Thanks,

    Bill

    I'm a believer!

    No, I'm sorry to hear about your issue. Glad to hear you are alright, never know what a machine can really do until something bad happens.

    Bill, I kinda hate to suggest this, but are you sure the blade was right side up? Were the teeth pointed up or down? This is the Voice of Experience asking the question; I've seen cuts like you described when I've installed the blade upside down. Especially for rough-cutting bowl blanks, I'd think the 3/4" Timberwolf would have been cutting beaucoup straight long before things went 'sproing'. Unless, of course, it was upside down.

    I'm still a doubter (mostly because I know myself so well ). However, if it turns out you busted the saw because the blade was in updide down I'll consider you a contender. Maybe we can schedule a "doofus-off".

    Well, I shall just take this as a lesson learned from somewhat else's mistake. Yep, the typically constructed 14" bandsaw is really not capable of applying proper tension to a 3/4" wide blade, but I had been thinking that maybe the Timberwolf blades, which are advertised as requiring less tension, might be an exception. Think I shall forget about ordering one to try out.

    Now we'll just have to see if Bill can turn this to his best advantage when you consider Doorlink's response to the incident. This being a family rated forum, I'll not venture further along that line. As to Bill being an absolute Doofus, I'll simply say that he does have a tendency to have "stuff" happen to him. Not Doofus, maybe just some bad karma.

    I keep reading that typical 14" bandsaws can't properly tension a 3/4" blade, but I've had success using a couple different ones on my Shop Fox. Don't really know if it was tensioned to what others would consider a proper level, but it cut wood and didn't wander. I gotta say though, that the 3/4" Timberwolf "resaw" blade I tried was a bit underwhelming. It didn't strike me as being any better than my 1/2" Woodslicer. In fact, the Woodslicer leaves a much better-finished cut.

    No sure I'm following your logic here, Bill. How does cutting the corners off make rounding them up with a smaller blade any faster? Looks to me like you're adding a step, not reducing time.

    Even Timberwolf doesn't recommend using a 3/4" blade on a standard 14" band-saw, at least they advised against it when I talked to them. I have both the 1/2" Timberwolf blade which works great & the Woodslicer which I haven't tried yet.

    since when do you read instructions bart???? the corners being gone would make the next cut alot easir to do with the smaller blade.. but i thought those spinny things made stuff round

    Even if the corner cuts went all the way to the line of the circle, it doesn't seem like it'd speed things up at all.
