So, we have this board full of header pins that hold a vertical board full of leds, unfortunately the pins protrude too much outward from the vertical board, and we had to cut them down for the fifty prototypes. The board has 70 pins, and cutting them by hand is just silly…(and as always, one of the topmost thinking heads, valorated cutting them by hand…yeah, they’re so naive sometimes.)
So, here it is, Quickfix number 3, weekend improvised miniature circular saw/grinder:
Yeah, it’s kinda botched, isn’t it? well, this is what I was cutting before the laser exploded (i.e. pressure cracked) so I had to make do with the piece and a half I had cut, and leftover pieces lying around. Add some RC parts (10Amps brushless driver and a cheapass servo tester), machine an adaptor (3mm to M2 screw) and there you go. (yes, they pay the material AND time I spend making these things at home, isn’t that wonderful?)
Since the laser died, I was unable to cut the pieces as I would have liked, so, instead of adjustable depth, I glued a pair of FR4 strips to the top surface and finely adjusted disc position through spacers (wich make a pain in the ass to change discs, by the way).
You can’t know by the photo, but I’m wearing two pairs of gloves, because the leftovers where so hot they burned my skin! I didn’t had better gloves around, so I had to make do with those two pairs. I still felt some really hot ones, but was just bearable.
Once I have the laser operative again, I’ll redesign it all, putting an engine guard against dust and add adjustable depth, amongh other things. A thing to note, I never thought about header pins and magnetism. Be careful with a setup like this (with no guards) header bits might get between the windings and magnets, and shatter something.
And then, when my least favourite boss comes around, asks “Does this really cut?”
After all these years and you still ask that kind of questions when I’m involved?…Really??
