    funny thing is I could have saved myself a lot of trouble had I just ordered the sprockets bored to size with the keyway already in them. it was a 4 week lead time and 4 times the price. a real no brainer there
    Never try to tell me it can't be done

    The family rule is "If dad didn't bleed on it, it isn't fixed yet." And I've removed a few small chunks. Only one needed stitches, so far. I have also outgrown the feeling that I'm impervious and immortal. Something to do with needing two total hip replacements in the past 15 years. If you just wear out body parts, you can't very well be impervious.

    be safe
    A small 'throat plate' opening is important regarding vertical action tools such as die filers and bandsaws. If you can hold part down, all goes well; and cut surprisingly close patterns.
    The reciprocal cut of die filer is aided with a hold-down; an overarm maintaining light contact with part. Some use a spring and roller, others a finger or ski shaped leaf spring bearing down with light pressure, while you maintain the feed rate.

    Clever but wondering if you also mount more than one blade in the jigsaw to increase the cutting width..?

    My Dewalt has a collet type blade lock that will only open wide enough to accept a single blade other brands may have a different means of securing the blades.
    I found that making 2 cuts at just under the finished keyway width then slicing out the remainder from between them worked very well. then I finished the keyway with a small file. I always try to make my keyways as near to dimensionally true as possible.
    Even when I has a broaching machine I would finish the cuts with a file. I have made a statement before about files. I love them and they hate me. New files get treated like precision instruments old dull files become scrapers or knives I can mill a head or deck an engine block and set the fit of a V8 intake manifold with a large file to almost the same precision as a CNC mill or surface grinder it just takes me a while longer.

    If what you say ("If dad didn't bleed on it...") is true...

    Then I have fixed a whole lotta s**t over the years. I got a new hip almost to years ago (at age 58) because the end of the femur died. I had my 9th back surgery earlier this year and just and the nerves in my elbows worked on. My motto is stolen from Monty Python's "Holy Grail" "It's only a flesh wound!"

    I've been avoiding knee surgery since I was 19, had my first hip replacement, the right hip, when I was 54. Doc thought it was necrotizing, like yours, and they went in to do arthroscopic surgery in January while I was still 53, and the joint had worn out again by my birthday in May. August the replaced the joint. Then again for the left at age 59 for the left hip. Still avoiding the knee surgery, and have had lots of steroid shots in the back, and the second instance of burning out the nerves there was a week ago this past Friday. Back doc that fixed my wife's back and got her out of the power wheel chair a decade or more ago, told me that there was a 50% chance they could fix my back, and a 50% chance they'd make it worse. He suggested I not have the back done until nothing else helps. I'm with you, there! I'll stop fixing stuff when they nail the box shut.
