I have a dilemma along with some questions.

First I want to say that I’ve always purchased my blades from a local supplier which I believe to be simple carbon steel, he makes up what I need and does the welding on them, I’ve only purchased name brand blades a few times, not enough to compare to his blades as his has always done the cutting and jobs I’ve needed aside the fact that he only charges $10.00 per blade.

I just had two of his blades break right in a row fresh on the wheels without a warning or a clicking they just popped.

My dilemma and question is that his welds have a tendency to break from what I’m experiencing, is this (common or normal) on name brand say timber wolf, Olsen, Carter, slicers etc….?

He has another person that comes in to help out on occasions and I’ve noticed or it seems I’ve never had any of his welds break (coincidence?) I don’t know, the blades in question are 3/16” 14 tpi 105’s I tighten them using Alex Snodgrass video instructions even leaving them a bit looser at times so I know they aren’t stressed.

So the main question is do big name brand blades have a tendency to break even if you have the tension correct or more to the loose side?

Thanks

If the blade snaps at the weld, very soon after installing it, the weld was most likely not sufficiently annealed. The welding hardens the steel and leaves it very brittle. You need to heat it up again and soften the weld metal (the term is actually “temper”). Whoever is making the blades should be doing that and you may want to ask them that question.

Randy, it is a bad welding job. Take them back, they can grind them a little bit and re weld them. Maybe the guy that did the welding, did not anneal them afterwards. You always have to do that because the weld itself is really brittle,

I buy a lot of blades from a local guy that has industrial grade stock and they last a long time, but I had one break and he fixed it in 2 minutes!...........and it held fine.
I used to weld a lot of blades in the tool room and the welder had an annealing button on it and you can see it change color in the welded area just for an instant.

cheers, Jim

Bad Weld for sure Blackie! I’ve never had a BS Blade Snap On Me.

If it did I’d be Upstairs Changing My Drawers shortly thereafter!!

I use Lee Valley’s Viking Blades (Previously Timber Wolf.) The last one I bought was a 1/4”, 6tpi, for $22.50.

I think these blades are as close to Perfect as you’re going to get. From Sweden and the back Edges are Pre-Rounded.

I usually have them pretty Tightly Set and I’ve yet to have one SNAP (GEEEEZ) on me.

just from experience, I [and the kids] use Craftsmen blades, which are about $17/piece. when things are going good they will last a year+, but it only take one knucklehead to push/twist to fast and I’m changing it again it a week.

In over thirty years of band sawing I’ve never had a weld break. It’s not common.

Rick,

I’ve snapped quite a few blades and it is really not that eventful. They just stop cutting and the wheels spin for a while.

I agree with Hydro. If they break they just stop there because there is nothing driving them. with all that said I will go on to say I would NEVER operate a band saw without all the doors over the wheels. That could get dangerous but a broken blade is nothing more than startling. It just stops. I have bought all my blades from a commercial line like Craftsman or Olson or someone like that. Off the store shelf. I have broken one or maybe two in the 35 years I have had a band saw.

I have never broken an Olsen All-Pro blade. They run about $20.
If I resaw much, they start to dull. It makes me wish carbide tipped blades were available at a reasonable price.

Thanks for the Reassurance Guys!

Never happened to me so I guess I was just Picturing what it would be like if it did happen.

Good thing though. I’m getting kind of low on “Fruit Of The Looms”. ....LOL…

Rick, it’s happened to me so much the shell shock is no longer. LOL

After reading all of these replies and viewing a video on how they are welded I see no reason why his should be breaking so if he wants my continued business I plan on drilling him with the questions that I’ve gathered from all of you in your comments thanks a bunch!

I’m not going to sugar coat my questions either I’m going to be blunt in asking him how he does his welds the whole process does he anneal them and how many times etc….

Thing is when I spoke to him on the phone to let him know about it, his response was “well it happens” according to you all here (NO IT DOESN’T) and I plan on mentioning to him what I’ve learned here as well.

I also have never had a blade break in 20+ years of bandsawing. The $10 deal quickly disappears if the blades continually break. I would go to a “name” brand or a different supplier. I’ve had a few made up at a local supplier and they have never broke.
I usually go with TimberWolf. Readily available at several outlets and online.

Rick FYI … Viking is Lee Valley’s name for the same blades as TimberWolf. From what I understand they are both made by the same Swedish supplier.
