    Lightbulb Band Saw Blade Soldering Jig

    Hi all, firstly, no laughing.

    I'm a woodworker not a metalworker (although I'm trying)

    Secondly, this is my first attempt to post a mini tutorial on this forum, so bear with me.

    Here is a band saw blade holder for when I used to have a small band saw and break blades frequently.

    These are your basic ingredients:

    Basically a piece of square tubing with a slot cut out in it and some flat metal, both about the same length.
    Drill some holes to match whatever size bolt you wish to use and use a tap to make a thread in the tubing only.

    Place in a vice to hold the jig steady.

    You then simply break a blade or two (I was getting quite proficient at that!) then file/sand/grind the two ends to form a scarf joint.

    Solder away until your heart's content or you finish the solder joint

    As you can see from my soldering, I am a woodworker

    Judicious use of a grinder will smooth the blade after soldering and make you look like a better metalworker, but don't be fooled.

    Hopefully this post works. Feel free to ask questions - somebody more skilled than me will be able to answer

    By the way, this was from many years ago - I now have a much bigger industrial band saw and have never broken a blade. Just as well, since I can't find the jig anywhere.

    Regards

    Yes, that's very good, I think I will modify mine to have the same system for clamping as yours.
    I like the fact that the two blade parts are aligned by the shaft of the screw, that's a great idea. You need to take care when drilling the four holes so that they are well aligned.
    Thanks for the trick !

    Thanks Christophe.
    If I remember correctly (always a gamble) but I reckon that I clamped the flat to the square tube to drill the holes 'accurately'.
    It was a long time ago now, but being as lazy as I am, that was probably how I did it

    Regards
