Totally the wrong tool for the job, but I found myself not having anything small enough to cut a keyway with in a 5/8" bore other than to cut them entirely with a file. I clamped the foot of my saber saw in a vice then used it like a die filer to rough cut the small keyways in several sprockets then finished them off with a file it really saved a lot of arm motion.

My machine shop teacher told me that there no wrong way to do a job. There are better ways, but no such thing as a wrong way.
So long as when the job is done, you still have all your body parts properly attached, and all your blood is still inside your body where it belongs. ;)Quote:

I don't have a shaper and may have to steal this at some point. Well done, sir.
My dewalt saber saw is variable speed so I could go as slow as I felt necessary. Holding the small sprocket by hand can get dicey fast so if you use this idea I recommend a plate with a slot in it so the part you are cutting has a full bearing surface to rest on.Quote:

Jigsaw blades cut on the pull stroke while needle files cut on the push stroke. This means that needle files must be mounted upside down in the jigsaw. You can see at least one way of doing it in my miniature die filer article...Quote:

Frank, Nicely done! Yes, I agree necessity does have a way of making us think outside of the box sometimes. Well done.
I was given my first set of real tools at the age of 4 and it's been down hill since. what they haven't been able to sew back on has been able to grow back... so far...
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
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. ;)Quote:

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.Quote:

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.
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!"Quote:

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. ;)Quote:

thank you........good idea.....
Well the wrong way is when the doer or somebody nearby gets hurt. That being said there are probably 100's of ways to get a job done safely.Quote:

That is true but there are a lot of methods which should not be tried by novices.Quote:
