When using a grinder, the shower of sparks will set your clothes on fire.
Wish I had thought of that name.
Do tell your kids not to be so anal about chain tension on their BMX bikes as to attempt to check said tension, while coasting down the road with feet on pedals. When they lean over and lift the chain with a finger, their foot will press down on the pedal and reel their finger into the chain ring.
(Okay it was me around 10 yrs old. I was stuck with a bike on my finger at the chain's tight spot or just before it. No free wheel, bendix brake on mags, so no backing it out. A neighbor decided to try to pry the chain off with a shovel, thereby tightening the chain on my finger.
I sent my friend back the two blocks home to get my parents and some tools to get the master link off. Actually don't remember getting out of it but needed lots of stitches and my right index fingernail still grows kind of odd towards the tip.
I spent more teacher work days getting stitches than I care to remember)
Remove drawbar wrench before turning on vertical milling machine spindle.
ouch... at least i got mine out...
Memories - that was 27 years ago for me, still remember it clearly.
So will sparks from cutting iron beams with gas/Ox.
Check that your vintage beetle is in neutral before casually reaching in the driver's window and hitting the ignition button. Even at a mere 40hp, that freshly-rebuilt engine is torquey enough to break the back tires loose, and you're bound to startle the cat.
1) When working under a car ALWAYS disconnect the battery.
Had a friend working on his 69 Camaro and crossed the starter connections
and it lurched forward falling off the ramps. It pinned his head between the
frame and ramp. He was there for over an hour before his parents returned.
The wall was covered in blood where he was screaming for help. He
survived. He has a nice plate in his head. He is now nicknamed lumpy.
Less damaging but far more humorus, had a job setting up computer furniture in hospitals, office buildings Etc., allways during business hours. Myself and a helper get on an elevator, (empty thankfully) on the 7th floor, I have a toolbox, he has a 50' extension cord.
He's dragging several feet of said cord behind him, door closes on cord, elevator decends and the cord begins to run out like a lure hit by a Blue Marlin.
Him "what should I do?"
Me "let go of the cord".
Him "then what?"
Me "act like nothing happened."
Holy Crap Shrimper THAT was funny....and about the drawbar wrench....did it turn it into a flinger across the shop?
When running the spindle clockwise the wrench hits the motor housing and unscrews the draw bar, thank you Bridgeport!
Had it been a left handed tool there would have been much
In my youth i was replacing the front tire of a VW beetle that was on a scissor jack.
The wheel had attached itself to the hub so i grabbed the wheel at the six and twelve o'clock position and rocked... it off the jack
My hand was caught between the tire and front fender for more than two hours before someone heard my screams for help.
Grab a stuck wheel at the nine and three o'clock position before yanking on it.
This is my new favorite thread- keep 'em comming.
Hmmm. Stupid machine shop tricks...with vertical instantaneous learning curves...
Even with it set as slow as it will go and being cautious, do not drill a 1-1/4 hole through an 8" thick 50lb block of lead with a drill press.
The image of that block of lead tearing itself loose from the hold down clamps and swinging around on the bit then snapping the bit and sailing past my shoulder at a bazillion mph with part of the drill bit jammed in it and hitting the opposite wall of the shop before falling to the floor is permanently etched on the inside of my skull. Lesson of the day: The first several inches are fine but after that, it seems that cooling lead tends to contract and will grab onto a drill bit and won't let go.
I have a plethora of stupid mahine shop stunts, (comes from living in one for over 30 years!) fortunately, most of them are Not from me as I was merely a wintess. For most of them anyway......
One of my favorites was from when a buddy and I used to work at General Electric in Albuquerque. It was and still is a pretty big plant. Huge high bays with 20 ton cranes that have 10 ton auxillaries on the same platform.
My buddy Paul who I had just met that week when I went onto swing shift was changing out a lathe chuck that probably weighed around 70 pounds or so. You put an eye bolt into the chuck, put a nylon (about 2 ton) strap through the eyebolt, attach both ends to the crane hook, raise it with the crane, swing it into place on the lathe, and tighten the cam lock fasteners to hold it fast. Then remove the hardware and you are ready to go.
Well the break bell rang so we went on break. Came back and as Paul was talking to another worker and distracted he proceeded to raise the hook on the crane so he could drive it back to it's parking space at the end of the high bay. Had he been watching what he was doing instead of still shootin' the bull he probably would have noticed he had not disconnected the strap from the crane.
There was this bizarre sound like a giant rubber band snapping taut and then vibrating as it stretched and got REALLY tight followed by this real LOUD BAM, followed by boingy, boingy. Paul had yanked one end of the lathe, (about a 6 foot bed 3000 pound turret lathe) clean out of the concrete and it was hanging from the crane with the electrical conduit hanging off the end and two chunks of concrete about the size of a fist still attached to the bottom of the lathe where they had pulled out of the concrete.
Paul thinking fast dropped it back down but it would not go back to a horizontal position as the two chunks of concrete would not go back down into their respective holes. I can STILL see Paul climbing up onto that lathe and jumping up and down on it trying to get it back level.
The other workers and I about died from laughing, and fortunately they did not fire him but did have to have a crew come in next day to re-set and level the machine.
If inflating an aircraft tire or any tire for that matter make sure you set your regulator to the psi you need before servicing. If you over service it the wheel NOT THE TIRE can shatter and it can and will kill you given the chance. Seen it happen.
Don't ever weld wearing only a pair of shorts.
A saying my Grandpa taught me while demonstrating how to loosen a frozen fastener with a torch . . . . "just cause it ain't red doesn't mean it ain't hot."
Do not completely disassemble the carbs on your vertical twin.
In the dark.
Under an overpass.
In the pissing down rain.
While you're monstered (before Nancy Reagan taught me to just say no).
Until you check for actual fuel in the fuel containment vessel.
Short version, change the petcock setting from RES to ON after fueling.
Not a stupid shop trip, but:
Never straddle a hot Kawasaki H1 in tennis shoes and let the pipe rest against your ankle. :eek1
And always have a cage or barrier between you and a tire when seating the bead. Watched a guy get his hand severed by an ATV tire bead that was defective and cut loose at a whopping 30 psi :eek1
Mine was more at like 2600 psi. Well it actually never got up that high but that is what the regulator was set at cause the guy before him never removed the setting and my friend never checked to make sure it was set low enough. Needless to say he learned his lesson after it blew half and I do mean half of his arse off along with 4 months in the hospital and numerous surgeries. His name is half-ass for the rest of his life...
