Let's see your bandsaw

Hello Again,
Here it is, it was in a thread about silver soldering blades and bits so I just copied and pasted below;

Hello Steve,

1, Trim the blade ends perfectly square, use a grinder as required,
2, Separate the two mounting blocks, now mount the blade into the blocks making sure that the join is "dead centre"
3, Apply force to push the two blade ends together, and while maintaining the pressure press the black button for just long enough for the blade ends to weld, you will know this has happened as the blocks will slide together, if you continue to hold the button the new weld will melt away completely,
4, Allow the weld to cool, you need to anneal; while maintaining the pressure on the sliding block tap the weld button (or annealing button if you have one) lightly while watching the blade between the blocks you should see a discolouration, do this three or four times but never let the join get to red heat otherwise you will need to repeat the annealing operation,
5, Remove the blade and grind off the flashing, dont forget the edge with the teeth on it, as a lump here is not good the lump can break off in the cut and all your teeth will run across it
6, If you still have breakage problems, remount the blade in the welder after grinding for one last annealing step, so that is one very quick tap on the button, before you reanneal, put a drop of light machine oil on the join and try to get the blade to a dark straw and no darker than light blue, evaporating the oil slows the heating process and the residue also slows the cooling slightly.
7, check to see the teeth are pointing the right way, easily rectified without breaking the blade but not everybody knows this, to rectify simply twist the blade until it "flips"

I hope this is of use to someone, this procedure is self taught as there were no instructions for the welder with bandsaw it is attached to, except for the safety warning about eye protection and a note telling you not to use the teeny weeny little blade shear to cut off your or other people's fingers, and I couldn't find any on the web or anywhere else, I went to the shop that supplied the machine and the Rep just shrugged.

With a little luck this may work on your welder, I suggest using the machine oil tip if you've already tried annealing the Bi metal, and remember that red heat is too hot for anealing these blades as a result of how quickly they "Air cool" if you use red heat for the first tap follow it up by further presses where it gets to blue and finally no more than straw.

Regards
Rick
