My 92 1/2" BS blades are "triple folded" and hang above my drill press table. Yesterday, I bumped a brand new 3/16 blade off the hook and it fell about 20" onto the wooden DP table. The weld separated, trashing a $25 blade. Does this sound normal or was it a bad weld? I'm wondering how reliable the welds are on the rest of the blades. If they fail while in use, they could make one heck of a mess. Thanks for any comments and feedback. :eek:

Breaking a weld with that little impact is not usual. Properly done, the weld is as strong as the steel around it.

Bad weld IMHO. Probably good it broke in the fall instead of in the middle of a critical cut on your saw...

I agree with Jamie and Jim -- "triple fold" shouldn't have overstressed the weld since that's how most bands are shipped (and how most are stored, I suspect), and no matter how high it fell there's wasn't enough weight behind it that the impact should have broken the weld.

The blade's not trash, though; just have it rewelded.

Bad weld. Good timing.

+1 on the bad weld.

I remember a time when I "uncoiled" my BS blades by dropping them on the concrete floor and jumping out of the way!! Never broke a one.

By the way, I have refined my shop techniques somewhat over the years. I can now engage in combat with a blade without getting clawed up too badly, and don't have to resort to the "throw down" method.

Real Bad Weld!!!!!

I've bought a kit that lets me weld my own. Lee Valley sells it.

First time was a charm.

Da blade was bunk.

I agree with the bad weld
