Jesus walks into an inn and throws down a handfull of nails. The innkeep looks up quizzically. In explanation, Jesus offers a parable: "can you put me up for the night"?
Jesus and Moses are out golfing. They're on a hole with a water hazard. Moses says to Jesus, "I think you should lay up." Jesus replies, "I saw Phil Mickelson put it on the green just yesterday." He hits the ball and it goes into the water. Jesus sends Moses to get his ball. Again Moses says, "I think you'd better lay up this time." Jesus answers, "no, Phil Mickelson made this shot yesterday." Sure enough, Jesus hits the ball into into the water. For a second time he sends Moses to retrieve his ball. Third attempt Moses says to Jesus, "You've put it in the water twice, just lay up." "Absolutely not, I saw Phil Mickelson make the green yesterday." Jesus hits the ball and yet again ends up in the water. He tells Moses to go get it. Moses replies, "No, I told you to lay up. You go get it!" About that time a couple arrives to see Jesus walking across the water to get his ball. They ask, who does he think he is, Jesus Christ?" Moses replies, "No, he thinks he is Phil Mickelson."
Isn’t it great though, when you meet someone who understands? Hasn’t happened with AvE missives, but it did happen to me with a Vice Grip Garage terminology.
I think the reason the safety micro switch goes straight into the brainbox rather than being a lockout is so that if you release the safety mid actuation the jaws will release back to the open position, rather than being stopped halfway between open and closed
@@ericl5973 I have one and can confirm. Also, releasing the trigger during close, will cause the blade to retract. It's almost too fast to react intentionally, but it's just another layer of safety probably there to stop the cycle due to an unintentional bump of the trigger.
I bought a cheap Amazon one like This Old Tony and immediately told my kids it's the most dangerous tool I have. I feel uncomfortable disinfecting the blades between fruit trees, and that's after I take off the battery.
I bought the more expensive Kebtek after watching this Old Tony. I like having it...just have to see how long it lasts. The 25V supposedly brushless version.
That's a bit neurotic, but then again, I'm hesitant to look down the barrel of my revolver (for glints of lead left behind) even after I remove the cylinder. So I get it. Maybe you should get your kids to disinfect it for you.
No kidding what was De Walt thing when they made this Battery Power Shear thing it is not so much about the Lorena Bobbitt thing that flipping thing would cut your fingers off before you even knew it even with the best Gloves on the market that would still cut through it like a hot knife through butter Dang hey i love tools but this thing can sit on the self
Funny story, I had an incident with a freshly sharpened hedge trimmer. Wearing ripped jeans, rushing to get the job done, thing comes down faster than expected through the unruly hedge and brushes past my knee. Didn't hurt at all, I thought it was just a little graze. Looked down and it had muched my knee down to the bone in a neat cut that looked like a McDonald's sign. Yep, needed stitches. I use dangerous tools for a job, but outdoor power equipment I have a bad history with.
@@Patrick-857 I have a simila story involving one of those chainsawr attach-mints for an angle grinder ... As get smart use to say, missed it by " that much... Let's just say the grinder was all burnt up from gettn my undies up in a bunch... Seriously I was afraid to look down..
18:22 The double actuation feature allows for use as a pruner or the jaws of life. The mechanics of it suggest it'll open with the same force as it closes. Edit: I think we need a follow up test.
I think the return function is there automatically so it acts as a safety feature, in case you release the trigger it opens to avoid capturing a finger/something. The logic is to turn off to a safe position.
@Honda si alte cele I think it's just ease of design. Especially with both micro switches. Ok... instead of the IC logic controlling the direction, i think it's mostly analog. Imagine the top switch doing the direction control. If the switch is on, it closes. If it is off, it runs in the opposite direction and opens. The lower interlock switch controls the power and if it runs or not. The magnet and sensor are actually a limit switch in the raw sense, interrupting the power at the end of travel. So pressing the lower switch enables or energizes the power. The state of the upper switch determines the direction of travel, and it is all interrupted when the limit switch is tripped at either end. But the limit switch is tied to the directional upper switch, so it only limits power in the directional state the switch is in.
@@bucharestpunk Mechanical pruning shears usually have a spring return to 'open' on release of the handles, this seems to be the action mimicked by the electric version. Copy the good stuff.
I'm a simple person. I think, great, automatic pruner. How many of those branches are going to be where I can reach with my hand? This doohickey needs to be on a stick with a remote activator.
That DeWalt cordless pruner is one of the best tools I have ever owned I cleared almost a half acre of overgrown bush with saplings vines you name it, over the course of a couple of months using that pruner and a five amp hour battery. Oh also bucked hundreds and hundreds of branches as big as Christmas trees with this thing hand mulching them up. I feel like this is 100 times more valuable than the sharpest machete. You can effortlessly cut your way in and out of the thickest overgrowth and undergrowth..
"You can effortlessly cut your way in and out of the thickest overgrowth and undergrowth.." Thanks, now I know what I should get the wife of a friend of mine for her birthday
I took a look at the parts diagram and all six of the planetary gears have the same part number "Part# N928176", so yeah, some organ donor put the wrong gear on there. Maybe odd sized gear 1s the same size as the pinion gear on the motor? The organ donor plucked the gear from the wrong bin? It's amazing that it still works as well as it does. Cheers from Tokyo!
hope you never tire of making these videos! I check every day to see if something new has been posted - now that i think of it - literally for years now. thank you!
The Catholic Church, because there's nothing more Christian than eating the flesh of Christ, and drinking his blood!! It's definitely not satanic in any way whatsoever. 👀
Reversing the motor quickly sends boatloads of back EMF through the motor brushes and mosfets, I used to accidentally destroy power screwdrivers this way.
@@garyblack8717 I'm trying to work out what's so terrifying about it. I think it's because it's so quiet and effortless in its motion. Things like chainsaws and grinders are much more dangerous but they're loud and angry, the dangers obvious. What's more scary? The loud mouth wanting to fight everyone with a bat or the quiet psycho with a cut throat razor? 🤣
@@garyblack8717 Not really since it has a safety trigger idk how ur fingers slip but. That def won't happen unless ur a dunce or don't have common sense or just clumsy.
I think it's partly ergonomics too. Like a chainsaw would be hard to turn on yourself accidentally or on purpose, at least without a kickback involved. The business end of this thing is completely within reach and easy to point at yourself.
This is a great tool I have a little 12v bosch pruner pro with a brushless motor and compact size. You can use special gloves with a cable that plugs into the tool, and if your fingers are close to the blades, the trigger does not work. Makita also make some great pruners with very good trigger feedback, you can control the exact position and speed of the blade with the trigger. Anyway I like your videos, we learn something in a very special way. 👍👍👍👍
This was seriously therapeutic. Watching you use an axe for an unboxing was epic. I have seen you demolish so many packages that I thought I had seen it all, and then you use a damn AXE!
I think I know why the two micro switches aren't in series. At 17:43, the jaw is installed between the two extremes of its travel and the battery is inserted. Under "normal" operating conditions, the jaw should move to the fully open position (as noted by the safety rant immediately following) however, the jaw does not move UNTIL the safety paddle is depressed. This seems to indicate that the safety paddle is (in some way) controlling the automatic opening action. I would be interested to see what would happen if the safety paddle and trigger were pressed and held until the jaw fully closes, and then the safety paddle (or safety paddle AND trigger) was released. If nothing interesting happens, then try closing the jaw (normally) and removing the battery. Then release all controls and reinstall the battery. The tool should remain closed until the safety paddle is pressed. Great find with that mismatched planet gear. Keep up the good work.
If the two switches are in series it may be possible to tie one down. Having them wired back to the microcontroller allows them to have an anti tie down timer programmed between them.
You are on the right path but I think you are over complicating it. Imagine the safety switch is just the power switch. The trigger switch is just a directional control. If you enable power, the motor just turns one way or another depending on the state of the trigger switch. Now here is where I think it confuses things. The magnet and sensor on the arm is a limit switch. So at the end of travel in either direction, the limit switch stops travel. When you initially enable anything, it is at the end if travel in the open position. You pull the trigger on the safety paddle, and you still have the direction in the open side at the end of travel (against the limit switch). This gives the appearance of both switches doing something more than needs to happen because the trigger switch needs to change the direction before you observe anything happening.
The reason for looking at each switch separately is because the lower interlock is there to keep the cutter from engaging. It does not stop the cutter from disengaging when the trigger button is released. It's a safety feature.
You could do that by wiring them in series though. I think there's probably some extra functionality being handled by the microcontroller. Something like if the lower interlock is held down for too long it times out, since that would indicate that it has been bypassed (e.g. by wrapping tape around the handle).
I could listen to AvE talk all day! By show off hands... how many of you watched the entirety of the hour long fire videos of just fire and a few comments? 🤚 I found it quite relaxing.
As far as circumcision is concerned, the real reason it was implemented that it was, because even God knows that Yiddish women won't touch anything unless it's 30% off.
Ditto, absolutely some of the best humour (spelling yes I am from England 😉) which I have missed during the last 12 years living in rural Ohio.... before has a rant at me, it's just an observation. 🤝👍🙂, keep doing these videos, informative, and funny as heck.
LoL it's funny. I just bought my mom that exact tool for her birthday and I had the same nearly irresistible urge to stick my finger in it 😁 She said the thing works great.
AvE: Quite possibly the best and smartest Canadian, in the world. I realize now why most Canadians don’t have a sense of humour; it’s because you got it all. Cheers.
Wifee got me one of those loppers for christmas. Pretty damn scary. It's so dangerous that the safety has a safety. Seriously, you have to pull the safety on the safety before you can pull the safety, before you can pull the trigger. It's like the tool is asking "are you really sure you want to pull that trigger?"
Sending all inputs, microswitches included, into the brainbox gives us options. Now the interlock and trigger can be used for secret squirrel mode settings in the brainbox, usually for production and testing but could also be used to set speed controls, double cuts yada yada
Gotta love AVE. He hit all the marks. Religious philosophy, a smiley face appearance, the entomologist debate to Friday afternoon manufacturing slap together expose' and tourist trap marketing... and beyond. BTW, you didn't link to the diamond culture - missed one... Missed it by a beard hair, or one a tad finer... PPM variable rate control w/mid stroke hold mod for increased horror coming next episode. Sounds like an Arduino project to me. I'm in - let er rip AVE!.
The separate micro switches may be a fail safe, avoids the issue of one getting stuck on, and then you unexpectedly cutting a finger off when you depress the safety trigger and it suddenly starts, or having it move immediately when you install the battery.
It's more likely two separate switches. The trigger switch is the direction switch about the paddle switch turns it on and off. The sensors on the arm are limit switches that interrupt the direction switch. The motor defaults to opening the blade and reverses when the trigger is pulled. The reason it seems different is because the arm is at the end of the travel path so the limit switch has disabled it. It gives the appearance that pulling the trigger starts something but it really just changes the motor direction which is why it's all the way on or off and explains the automatic opening when releasing.
Separate switches as separate fail safes makes no diff. If in series and one fails shut then the second operates immediately. If parallel circuitry on the board, and one fails shut (circuit board or mechanical failure) the second still operates freely.
Except the tall gear is loose, meaning it's bore has a larger diameter, meaning the ones in the gearbox have a bore with a smaller diameter, meaning they couldn't fit one on the motor shaft. And also the gear probably maybe, I don't know for sure gets installed on the motor shaft at the electric motor factory.
I'm surprised that you didn't have a hot dog handy for the initial lopping test. Also, the trigger action reminds me of M4 rifle I had in basic training. It would fire both when the trigger was squeezed and again when released. So I had to hold the trigger in until I acquired the next target then release. I still qualified.
somebody slipped you a binary trigger! i bet you could have done like the intentional binary triggers do and flicked the safety to "safe" and that release shot wouldnt chooch.
My mom has had a no-name brand version of one of these for years, same exact function, opens when you let go of the trigger and moves pretty quick. But the DeWalt version seems quite a bit stronger
@@bipedal-ape-man The comment is from a day ago because he's not one of us plebians who has to wait an extra day for the video to become public. If you throw a couple bucks towards Patreon you get early access to scream into the void of RU-vid comments a day before the unwashed masses.
Reminds me of the joke about the guy in the dessert looking for water. He's pointed to a restaurant by a "random individual" who sells clothes. He returns an hour later and says "Your brother said I have to have a tie to enter"
The only thing I can think of with the independent interlock switchs is that they only want the trigger to be the trigger. I see that the mechanical design prevents that as well. Considering that, the only remaining explanation is that the spark-e's neither trusted nor communicated with the mech-e's.
It's probably there to keep you from just taping it down. It might check that the second switch is open when you plug in the battery. Try taping it down, then sticking in a battery and see if it works then.
I suspect the safety is an interlock switch initiating power and communication and the trigger can't function if this fails, two switches in series aren't as safe. Would need to reverse engineer or probe the board to know for sure
You can tell when he is testing it on the half-shell that the logic is that it will open only when the lower handle switch is closed and the trigger switch is open. If both are open it doesn't do anything. To do that it needs to be able to tell the difference between those two states.
The reason for having the switches independent of each other is a simple fail safe against the unlikely, but not improbable condition where one of the switches becomes stuck on through mechanical failure or intentional misuse. The controller then has to see that both switches are open before allowing acceptance of the run switch. If either is closed when power is applied the controller will fail it's startup status and prevent operation as it did with the frame open. It's what's known as intrinsically safe. Imagine if you will a user is careless enough to be holding the tool by the grip and activates both switches while installing the battery. If they were in series the tool would activate the instant power is applied and whatever unfortunate item is in the blade's shear path would be instantly permanently disconnected, or at the very least significantly mangled.
That is a pretty fast Chopper you got there. I have one of the Milwaukee M12 PVC Cutters and it goes a lot slower than that monster. It’s interesting that the planetary gear was wrong, I wonder how long it will last before it fails. Thanks for the commentary, laughs and videos. Always appreciated.
Both switches going to the board is important, when the interlock is pressed the machine is on and will home open, when the second one is pressed that is a forward command.
My asian batt pruner has a safety feature that disables the blade and gives you a chirp signal when you touch the blade with your free hand. Love it, has made my orchard work possible for this 71-year old geez.
Fun video. Thumbs up. FYI: The literal translation of "mitzvah" is "commandment." The 613 mitzvot of Torah (commandments of the law) are not optional. They are not about making your life more difficult to get closer to Hashem, but about choosing "blessings and life." At the time of those commandments in Leviticus pagan rituals included tattoos, trimming the hair in a particular fashion, and trimming the corners of the beard. These commands were given to keep Israel separate from the pagan nations. The Hasids certainly take it to an extreme. There's really no arguing that.
I reckon the reason both microswitches are individually wired back to the brainbox is so it can sense if you've tried to bypass the mechanical interlock by taping it or putting a rubber band on it. It's looking for a sequence of events as well as just the closing of the switch contacts. Thanks for the videos and stay sweet 😀
This is the correct answer. I bought these last week, and if you keep the interlock switch pressed for too long without pulling the trigger, it disables the trigger until you release the interlock switch and press it again. It’s an intelligent anti-interlock-disabling sensor.
That is fast little bugger! Almost as fast as a lumber mill automatic cross-cut saw... that some running dummy in management took his arm off with. By the way he was in charge of plant safety.
I've got a makita LXT compatible non branded pruner like that, but its not the size of a sub machine gun and does not have the annoying safety switch, I am a gardener and have had it 3 years now, my loppers dont get a look in any more, use it all the time, still got all my fingers too (so far)
These pruners are cool!!I have an extensive collection of pneumatic pruners… as I was an orchard owner for years. Isopropyl by the gallon into to tank of the pto driven compressor to keep everything but your hands from freezing up. Dec, Jan, Feb are the prime pruning months because the trees are dormant…I wish I got a 3 month break.. So much work to have a May freeze or a July hail storm make it all for naught.. Where was I…Grapes! These would be great for pruning grapes
Lock that thing in the gun safe. It should come with a trigger lock😁 I'm surprised your illustrious Commander in charge doesn't out law these to protect you from hurting yourselves or others.
I believe the saw stop technology works on a moisture sensor of some type and pruning green limbs would trigger it, I’ve heard that even under dried lumber can set it off
Is there a torque limiting feedback type of dealio or will it just crunch itself to bits without knowing any better? Will it cut a bolt right half in two?
