Very funny intro to today's woodwhispere...

I will only say that there is some tongue and cheek mention of saw stop and its rather funny. Check it out, todays episode, lol.

It's the old secret lawn mower accident. Actually, with all the shop electrical I've done on several shops including panels, different voltages, and 3 phase, the worst shock I ever got was from a lawnmower. I was a kid cutting grass when the plug wire was coming loose, and I grabbed it (like fool), and man did I get knocked off my feet.

As for the video, I did notice that Marc should have mentioned when pushing stock into a stop block, that it's possible to nudge it a bit if the block isn't absolutely tight. He did show adjusting it by tapping which shows how easy it can move. If doing batch work, it's easy to get into a cadence and loose track of the movement speeds of the stock into the block.

I usually make a habit of spot checking its placement before ruining several pieces.

Thats a good point C-man, one could get a little carried away when doing a batch and start to "slam 'em home" which can move the stop block. I would think that doing that would also ruin your tenon fit as the blade would start to flex and wander. Great reminder to check your setup periodically, especially with large batches.... I forget this often myself.

I'd be willing to bet that there's a story behind c-man's lesson learned--hope we get to hear it.

My small engine shock was mini-bike more than 40 years ago. I still remember not to grab the plug wire--but until this morning i'd forgotten where i learned it!! I'd agree, the worst shock i've ever gotten.

I did the same on an old CR 125 with a broken kill switch. After a good shock I decided to shut the fuel line off and let it die on its own.

Old Televisions had 38Kv of DC voltage going to the shield around the picture tube. You did not have to touch it to get bit. If there was dust on the sheild and it was a humid day, it could jump almost 3 inches to get you. The shock was low amp but when you jumped and/or pulled away you could do some major damage to your elbow when it hit the wall behind you. Being low amp would not kill but if it got you for more than a second it would give you a small area of deep burn. The system was a large capacitor and could hold a charge for weeks.

THAT'S my problem! I usually spot check after ruining several pieces.

Don't we miss those old CRT tube televisions!
The insidious thing about the anode charge on the tube was that not only was it a large area capacitor, it was also well distributed and if you discharged it like you were supposed to before handling, it could recharge itself from the distant plates over several seconds and still give you a wallop of several kilovolts. I never had the pleasure of this myself but a fellow EE who was working on his TV told me the story of how he thought he died when he got zapped. His next instinctive thought was to run outside so they would find his body!

Not just one story, there are many. Any time a stop is used for repetition, I make a habit of checking it. The first time it happened, the parts kept getting larger. So, stops on any machine can be a culprit.

I worked in a materials testing lab. One day we were running a particle deposition test for a container that would house the silicon wafers used by Intel. Well the setup was all on a metal cart that was on some pretty heavy-duty castors. The power supply running the equipment was in a metal housing. I don't remember what exactly the deal was, but the system wasn't working.

I touched the cart to move it back, and BANG! There must have been some sort of short with the power supply, because a huge charge was built up on the cart and I got a static shock about 1000 times worse than touching a doorknob. I remember hearing the bang, and my fingers tingling a bit. Thankfully the power supply was unplugged at the time!

Worst shock I ever had was when I was working on the phone wiring in my house..
I was putting the wires on the posts for the outlet when the phone rang.. WOW..
90 volts AC @ 20 hz.. That will get you hopping!.

2nd worst was messing about with an MSD 6 ignition on the bench.. They aint kidding when they call it multiple spark..
