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.
With larger blade and with blades where a strong joint is needed you will braze. Too much heat, taking too long to get silver braze to melt will cause flux to get used up dissolving oxides and go black and no longer work and also more time for blade to expand and the overlap joint to slip over it self getting a thicker joint with possible thin spots on both sides after grinding back. File or grind the blob of solder off flush with the surface of the blade and flat off the blade edges to allow smooth running of the blade through the saw guides.
Sounds like freebie blades to me – silver solder as above – don’t keep the heat too local and let them cool slowly ………….sorta ”warming them down with the torch” – if you get my drift. 07-31-2016, 05:00 PM #13 cut the blade at a 30 degree angle and bevel the edge and you get about 4 times the blade cross section for silver solder to adhere to. For doing several blades at one time I think silver brazing is faster.

How do you anneal a bandsaw blade?
To anneal, I always shade the weld with my hands to keep the weld darkeded from the ambient light.

Remove and test the weld buy bending the blade to a 8″ or 10″ radius.

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.
How long do bandsaw blades last?
On average your bandsaw blade should last 6 months to as long as a few years depending on what your cutting with it. Make sure to match your blade strength and quality to the project and material your cutting.
Is it worth it to sharpen bandsaw blades?
Since a carbide-tipped bandsaw blade will cost well over $100, spending a third of the cost of the blade (or more) to get it sharp and working like new again can make financial sense. However the majority of bandsaw blades, the Wood Slicer included, are not worth spending money to have sharpened.
How do 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.
