Be/mqhsZl cseA. I know many of the bandsaw blades appear to be spot welded together and I don’t happen to own a spot welder by I have read of people who have solder the ends together with good results, so that is what I am going to try. From what I learned, the best way of getting the 2 ends together is with a “Lap” joint, which is where the 2 halves of the blade overlap, but instead of being square, I will need to grind the matching ends of the bandsaw blade in a bevel shape to help reduce the bulk that would happen when you overlap a could of bandsaw blades. I fired up my propane torch smeared an abundance of flux on the aligned bandsaw blades and just ran the flame through the joint until I could get the solder to melt at which time it flowed nicely between the 2 parts of the blade.
The material in the middle of the clamp was removed to allow the join to be made without soldering the blade to the clamp. It means the finished blade length will be shorter than before but this should be well within the tension adjustment of the bandsaw. Once the blade has cooled, the braze should be filed to make it smooth and flush with the thickness of the blade.
The “Official” way to make bandsaw blades from coiled stock is resistance butt welding as performed by the kind of welder you find on the side of better contouring metal cutting bandsaws. My experience is the resistance welded band properly done is as strong as the parent band stock and if done really right no teeth are damaged in the weld zone. “My suggestion is to scout up someone with a band welder and coax or rent time on it. Once your get rolling you can cut, weld, temper, de-flash, and grind flush a saw band in a couple minutes, no more than five anyway. The typicasl band welder’s built-in grinder sucks. A fine grit parting wheel in a 4” angle grinder is my go-to band dressing tool.
To solder the blades, you will need silver solder and flux. “You will need to know the finished length of blade that works on your saw. To get the measurement either check the owners manual or take a used blade and cut it to measure. I add 1/8” to the total length to allow for the solder joint. Let the blade cool in the fixture and grind the face of the blade smooth.

Can you arc weld a bandsaw blade?
Luckily for you, though – a broken bandsaw blade doesn’t have to be the end of your work. What is this? You can simply weld the bandsaw blade back into shape. Through this article, we’ll explain exactly how you can do that, as well as the importance of doing so when necessary.
What is a blade welder?
The T27555 Blade Welder can cut, weld, anneal, and grind bandsaw blades. This allows you to make new blades from bulk coils of band stock. Quickly rejoin a blade that has been purposely cut for making an internal contour cut. Repair broken blades that are still sharp and useful.
Does welding melt metal?
Joining Metals As opposed to brazing and soldering, which do not melt the base metal, welding is a high heat process which melts the base material. Typically with the addition of a filler material.
What do you do with old bandsaw blades?
There is life for those old, broken, and dull bandsaw blades. Just cut the old blade into sections about 12″ long. Stack the pieces together, alternating the teeth so that they don’t touch their neighbors. Use either same tape, or just braze the ends together,.
Can you fix a bent bandsaw blade?
How to straighten a bandsaw blade? It is risky but if it’s absolutely necessary, a temporary fix to straighten a bandsaw blade can be done by placing it on an anvil and gently tapping it flat with a nylon head hammer/mallet or using a pair of gas pliers to straighten out the blade.
Which way should the teeth face on a bandsaw?
On a typical wood or metal cutting blade the hook or of point of the blade should be pointing down for a vertical blade bandsaw, or for a horizontal blade saw the hook of the teeth should be pointed such that they enter the workpiece first as the blade moves.
How tight should my bandsaw blade be?
The blade should deflect no more than 1/4 in. A good place to begin is to tension the blade until the meter reads proper tension for the next wider blade. For example, if you’re tensioning a 3/8-in.
