Maybe someone else can give you a better method, but I, too, have always found silver-soldering to be better than welding – even a proper blade butt-welder will form a hard spot at/next to the weld,which must be very carefully annealed after the weld is ground down or filed down even with the rest of the blade. Whenever I used to do blades in a Do-All bandsaw butt-welder, even with careful annealing, about 1 in 4 blades would fail next to the weld line within a short time – when I did the tapered overlap cleanly, and got a good seam, I have never had a silver-soldered blade break at/next to the seam. Once upon a time…. stuck in a shop on a mountain in the M.E. without any blades or blade stock… we cut sections out of a number of old blades, different pitch blade too.
When you’re not in the middle of a project, take the time to try different annealing techniques with short pieces of blade material. Than but weld as will yeald an evenly smooched together joint… Atthis point I unclamp the blade and move the clamps to the annealingposition… clamp for annealing and pushthe anneal button untill the joint area and only thejont area is dull red and then tickle the anneal button to SLOWLYlower the temperature. I also havea small cheap cutoff saw and when I used bimetal blades on it, thesofter back part of the blade would fatigue at many many locationsaround the blade.

If you don’t have too much time on your hands, that’s completely fine, you can feel free to read our quick overview of how to weld bandsaw blades below. Why You’ll Need to Weld A Bandsaw Blade & How To Do So. Next up, we’ll discuss exactly when and why you’d need to weld a bandsaw blade, as well as step by step guide on how to do so. The Round-Up. Now that you’ve finished reading this article, you should have a fairly solid idea of how to weld a broken bandsaw blade, if you didn’t already.
“I have a Powermatic/Houdaille bandsaw blade welder that is probably 20 years old but has had very little use. I am using it to weld 1/2″ x.025″ blades for my 4″ x 6” bandsaw. “The detents for the clamping lever on the welder are not labelled, but I have found that the mid point works best for the blades I am welding,and that works out because the welder has a capacity of up to 1” blades. First correct any welding problem; I found the amount of upset during the welding cycle to be particularly important…too little upset resulted in incomplete fusion… too much upset squeezed out all the plastic steel leaving a poor weld.
how to anneal bandsaw blade Related Question:
Can bandsaw blades be resharpened?
There are two basic ways to sharpen bandsaw blades, mechanically, with the use of a machine, or machines designed to sharpen and reset bands, and manually, with the use of hand tools, or hand power tools.
Should you lubricate a bandsaw blade?
Band saw blade lubricant is essential for keeping temperatures low and stopping the metal or wood from being treated by the heat generated during sawing. In fact, heat dissipation is one of the primary roles of the band saw blade lubricant and coolant.
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.
How many times can a bandsaw blade be sharpened?
It often makes sense to replace a dull blade with a new one, but you can sometimes get the best value out of merely sharpening an old blade instead of replacing it altogether. You should typically be able to get two to three sharpenings before you need to change your blade completely.
How do you clean a meat band saw?
Clean the blades thoroughly using antibacterial soap or bleach and hot water to dislodge meat particles and germs that have clung to them. Sterilize by washing with hot water that is a temperature of 170 degrees.
Why is it important to use lubricant when using the blade?
The lubrication system acts as a blade wash, removing the hairs. For many products lubricating the blade also greatly assists the cutting action and eases the passage of the blade through the extrusion. This will reduce blade wear & lessen the cutting power needed to cut the product.
What oil do you use for a bandsaw?
BAND SAW KLEENKOOL is a premium quality oil specially formulated for the unique problems associated with high speed band saws. BAND SAW KLEENKOOL is engineered to lubricate, cool, and clean residue from band saw blades.
Why does my bandsaw stall?
Using a dull blade or the incorrect type of blade can cause the band saw to cut through work pieces slowly. The blade will also move slowly through the work piece if the blade is installed incorrectly. A weak drive motor can also cause the band saw to cut slowly.
Are bandsaw blades worth sharpening?
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.
Why do bandsaw blades break?
Machine Defects Even the best blades can fail if there is something else wrong with your bandsaw, and even a small misalignment of bearings or guides can put a twist in the blade as it goes around. Resulting in tension being applied in all the wrong ways which will lead to early breakage.
How long do portable sawmill blades last?
Some can last under six months, and some can last years! Some of the most important variables to consider are what you are cutting, the condition of the machine and blade, how long you are using the blade, and even how you are feeding the wood through your saw as well.
Can you sharpen sawmill blades?
In general, the sharpening wheel should be around half the length of the tooth pitch in thickness. You can also sharpen a blade manually by applying a Dremel tool to the tip and gullet. Manually sharpening a wide band saw blade can be a time-consuming process and requires a steady hand.
