Just wanted to pass along a quick note that we should all remember to loosen up the blade tension on our bandsaws when we will be away for a while…
I forgot to do that and guess what…..... “SNAP” there goes the blade… so in addition to scaring the woodbugs out of my system and having to check my drawers… I now have to install a new blade and hope that there was no other damage…
Not a fun experience, but at least my lesson didn’t cost me any fingers, only a bandsaw blade…

Keep cutting out there folks, only the wood, not the fingers…

Glad it was only your drawers and the blade that needed replacing.

Just curious. Does anybody do anything with snapped bandsaw blades? Seems to be a waste to just throw all those sharp teeth away. Just wondering.

Man I hate it when a bandsaw blade snaps.

If the break is relatively clean and straight, they can be welded.

Glad to hear you’re okay. I haven’t had one break yet, but I plan on making a bowsaw if I have one break while it’s still fairly sharp, because it does seem like a waste to throw it out, like you said.

If y’all will recall I upgraded my band saw with a Grizzly tension release assembly a couple of weeks ago. It was honestly because the stock tension assembly was a pain to use.

Keeping tension on the blade CAN cause them to snap, and usually puts undue stress on the adjusters, tension assemblies, bearings, etc… It is always a good idea that when you are done with using the band saw for the day, take the tension off the blade.

This is SO much nicer now that the entire detensioning procedure for me is just flip a lever over…

You can make a bowsaw out of broken bandsaw blades. That’s what was used before the ‘hand tool renaissance’ happened. LN and LV , BCTW and all those high end planemakers got into business.

Great idea for using the old blade for a bow saw… I still have to remove it from the machine as it jammed itself up the side shute pretty good… bent it in a couple of places so I don’t plan on welding it back together… I do have spare blades lying around the shop that I can use…
I will also be looking at an upgrade to the detensioning system as dbhost has mentioned, most are a pain to use… If it is easier, it will be used everytime… I have seen some people change out the knob for something they can attach their drill to and quickly add or remove tension, but I think I like the lever idea better… much safer and easy to do… Thanks dbhost and everyone for your replies on this…
Happy and safe cutting to all…

I agree with you when it happens to me.

Now when it is someone else, that, my friend is another story. I kinda enjoy watching new employees jump and run. I usually have to go turn off the bandsaw because they are checking their underwear. I know that’s sick—-there could be an injury, but I still laugh. It has happened to me so many times, I hardly flinch anymore.
Now I’m more concerned that I have to change blades.

up until recently ,
to my knowledge
everytime i bought blades ( at least 6 at a time ) ,
the companys would resolder them for free
if they broke on a weld , maybe they still do ?
i have also made bowsaws with the blades ,
but who wants a dull saw ?
by the time mine break ,
it’s usualy because they are dull .

When I was cutting out toys with 1/16” bandsaw blades I would get about 1 hr’s use before the blade snapped.

When it broke it was usually into a half a doxz pieces. Metal fatigue caused the blades to shatter.

I get a lot more life out of 1/8” blades.

Its always a good idea to release the tension if the bandsaw is sitting for a long period of time. Leaving the tension on all the time when not being used can cause flat spots in the tires too.

Hi it seems like I break alot of blades too not sure why it isnt from going around tight corners cause i have broke a few while sawing straight lines so i dont understand all I know about it. I would like to learn how to solder or weld them I made a thing to hold the ends straight at each other but cant decide to solder or braze them the companies electric arc them like a spot welder I believe but some i have bought arent even lined up straight if u look at them close. Does anyone know if solder or braze is the best I wind up with so much weld material on the break that i have to grind it all off then it gets hot and lets go so the last one i tried i had to file it off by hand and it didnt work out can remember what happened for sure but it broke right after I put it on never even got to saw any wood with it lol got a lot to learn about how to do it…..well thanks.
