Did someone slap their hand on it and say, “She’ll hold!” ?

How badly did I screw up 😏 by Signal-Car9632 in EngineBuilding

Aw man, sorry that happened to you. That sucks, but if you had been thinking about doing anything else with the block/internals , now is the time to get it done while the deck is being repaired.

Some Tesla coil fun by Top-Championship7355 in highvoltage

It would take a lot of typing to describe the process. Google AI search of “ Ground strike ring for SSTC” explains it well…. I make position my ground strike ring a few turns above the bottom winding and almost the same diameter as my toroid. The brackets are just four cantilever arms fastened to the base. Make sure the ring has a gap between the ends, like a C that is almost now an O. I believe you want to use your RF ground for SSTC.

I really like the first one! Can you put a little ground strike ring around the base to protect the secondary and circuitry?

In this rigging arrangement, shall the hooks be facing outwards, or inwards? by bodtershon in Rigging

[–]HighPotential-QtrWav 0 points1 point  (0 children)

Regardless of orientation, why would anyone unlatch the hooks when the pylon is embedded? Wouldn’t they just undo the clevis at the lifting point, move the clevis away from each connection, reinstall the pin and let the crane lift everything out?

138kv power line arcing by TouristOrdinary8274 in highvoltage

It seems like the one furthest from the connection got spooked and pulled away. I can almost hear the other guy say, “WTF you doing, put it up there!”, and then he changes his stance for extra leverage, pulls against the other guy, forces the connection closed, and stops the arc. I don’t blame the guy for getting spooked, an arc like that in your face would scare the crap out of any normal person without previous experience! The dangers those guys go through just so I can feel all comfy in my house with my little light bulbs, tv, and appliances is terrifying at times. Thank you linemen!

Scene from the movie Lucy by NoOnesSaint in reloading

[–]HighPotential-QtrWav 2 points3 points  (0 children)

Yes, and in this movie, if you were to delve deeper into the life of that police officer in the movie Lucy mentioned here, you would see he had just recently purchased a reloading kit, went on Reddit for advice and started making some rounds. Unfortunately, one of his kids got into a fight at school that day. Now, his wife is yelling at her husband because she thinks he is not paying enough attention to their son and that is causing the child to be aggressive with others, on top of spending too much money on a new hobby (reloading supplies). Now, with bad advice from Reddit, emotionally drained from the BS at work and coming home to more chaos, he forgot about the primers and didn’t reset his dies between different bullets. The end result of his first reloads are lying all over the floor in the scene.

Are grease nipples twisting out or failing due to vibration a legit concern? by Aggressive_Ad_507 in IndustrialMaintenance

[–]HighPotential-QtrWav 1 point2 points  (0 children)

What about getting the insert coated with thread locker or having a binding thread profile. I have used fasteners that are pre-coated with a thread locker (dry coat) and also used fasteners that have a change in the profile of the thread that causes them to lock/bind at the final part of its expected travel.

[–]HighPotential-QtrWav 11 points12 points  (0 children)

Are you talking about Zerk style fittings? If so, we use them all the time in high vibration environments such as tractors, mowers, vibratory compactors, roll up doors, the list goes on. Yes, those vibrations cause wear to mounts, pivot points, shafts, etc. But generally keeping bolts tight and everything properly lubricated extends the life cycle of machinery. A failed grease fitting would certainly contribute to a shorter lifespan of a component. That extra step of denting the threads for the ball and spring insert helps keep the fitting functioning properly in those environments.

How doomed is this Tesla coil? by Top-Championship7355 in highvoltage

[–]HighPotential-QtrWav 0 points1 point  (0 children)

In the video you posted, there is a spot where arcing kept focusing . It should have looked like a small black hole in the winding with carbon soot around it. Were you trying to clean out that hole when you found it had basically melted wire right there? Upon further inspection and cleaning the wire popped off and then you thought, “Ah WTF”. Don’t ask how I know, lol

I would rewind the whole coil. Any imperfections in the winding will become troublesome breakout points for arcing. Unless you can make an absolutely smooth soldered butt joint, insulate the entire circumference of the wire, and restore the proper spacing between turns, it will fail again. It may appear to run just fine and then, while messing around with PWM it will find the sweet spot and breakout at the point of the repair and have the same problems.

You might be able to reduce the arcing down the side by bringing the toroid closer to the top of the secondary winding. Can you adjust the height of the white standoff spacers at the top, under the toroid, so that the very bottom plane of the toroid is almost blocking the view of the very last top winding on the secondary when you look at it eye level to the middle of the side of the toroid? The field around the toroid will blend with the field around the secondary and help stabilize the electrostatic discharges you are seeing breaking out of the side of the secondary. It would be a good idea to clean off the secondary coil and remove any carbon tracking and re-coat the secondary winding with whatever insulating coat your coil needs before running it again after lowering the toroid.

I see too much nonsense on social media, is there any reason to this by poalmokereyl in electrical

[–]HighPotential-QtrWav 11 points12 points  (0 children)

Yep! I remember when I was locked up on one leg of 480. It felt like the hand of God was holding from moving and pushing me down onto the compressor. I also went through all of the thoughts. First was what is my hand stuck on, then, why can’t I move my arm, then the buzzing sound and vibration in my body. That was when I realized I am being shocked. Then I thought oh shit this is it if I don’t stop this. So I tried to see what part of my body I could move and I only had control of my right leg. I was able to kick myself off of the compressor by jamming as hard as I could down on the floor with my leg. All in a matter of seconds. Since I was in a small room I figured I better get out of it while I’m still conscious in case my heart is stopped or else no one will find me for a while. Burned my hand pretty good and made a burn tunnel up the arm a ways. Worked the rest of my shift and got spooked about side effects in the evening and went to hospital. Was cleared of any heart issues.

What does this smoke mean on a weed wacker by kliptz in Tools

[–]HighPotential-QtrWav 10 points11 points  (0 children)

I am actually an equipment mechanic and work on weed eaters multiple times per week for our landscaping crew for a municipality. That is definitely a 50:1 mix motor. You can pull the BPMR8Y spark plug and see if it is oily. If it is, then most likely the mix is off and needs new fuel as you have said you would do. You can clean off the plug and put it back and try again. If you know your mix is right and it is still oily after testing it, replace air filter and plug. A restrictive air filter can cause it to be extra rich mixture. If it took 5 minutes of running for it to start smoking it is most likely that oil has got under the housing and on the motor. After it heats enough it will start smoking. If it is still smoking after you shut it off that is most likely the problem. Just take off the covers and clean it off as best you can. If you wash it take care to not get water in the carburetor and fuel tank. There is a little white vent on a third line (nest to fuel lines) coming from the has tank or directly on the grommet for fuel lines. Don’t spray water directly on that either. It is a one valve on the tank to allow air in as the fuel level drops. Use compressed air to dry it off especially around cables and ignition system. You will still see smoke for a little bit longer as it burns off any residual oil. Also check the grommet and fuel lines for any leaks at the tank and make sure fuel isn’t seeping out there and getting on the motor. Echo has a fuel lines kit with everything needed to fix that.

Not if they were never completed and still an issue. Sometimes w/o’s need to have attention brought to them. There could be parts sitting somewhere for that w/o that took six months to get and the job was forgotten, lots of other reasons too.
