[@time1800]

Mine works fine but finding quality vintage models worth pulling out for is a problem.

[@jdinnis]

The wire that melted near the starter is probably a fusible link. It is specifically designed to melt at a specific amperage to protect the rest of the wiring. You might want to replace that with a new fusible link instead of just shortening the old one. By shortening the wire, it will take more current to melt.

[@Disneymkvii]

I came here to say the same. That's a fusible link.

[@thomasoo5726]

Thought also about the rest of the wire inside the loom would be cooked. But if it was a fusible link he may be lucky and should replace it to prevent future failures.

[@raymanbecker]

For a lower budget fix, just a fused jumper.

[@jeeper360]

That's what I came to the comments for too. Agree that it might be a fusible link.

[@onthelake9554]

Yep fusible link , better replace it .

[@Ivansgarage]

I have been a welder for 50 years, one thing I have learned, welders start fires.. one thing I have allways kept around is one of those, refillable big can extinguishers, that you can charge with air and water, put a tire fill stem in the top of the can, they hold like 3 gallons, they always work ....

[@muchmuchmore]

I'm only 11 minutes in and your model really deserves a video of its own. I somehow doubt anyone has taken the time to explain how this works in such great detail. Maybe consider an additional video with a title that matches "How a boom lift works'. Awesome content as usual!

[@stansmith9639]

Jon, I just have to say you would make an amazing science teacher (or any kind). The way you're able to simplify things and get your point across so clearly is a talent of it's own.

[@billnewman5900]

John you should have been a shop teacher. You are brilliant!!!!

[@advancednutritioninc908]

Anyone of us who actually have worked on equipment, has made a mistake like you did on the boom lift trying to get that pin out! You did a great job on the model - made it as simple as possible and yet it explains how the lift works! Stay cheerful you are doing great work! Thank You!

[@FishFind3000]

Seeing stuff like this just makes me go back to the “if it ain’t broke dont fix it” “leave good enough well alone”

Or… if it ain’t broke, keep fixing it until it is

[@gerhardii]

So Glad I found your channel a while back. Its interesting, educational, and entertaining. Especially how you take the extra time to build things just to more easily explain everything. You tackle many more projects than I ever would like this BOOM lift.

[@MarshallBF]

I absolutely feel the same about fixing my own mistakes, and I guess many people that care about their time have it that way.

I’m not a mechanical person, I’m in IT, but I really enjoy your videos because you don’t just fix things, you also try and make them better while doing so. It’s a lesson I try to teach newer techs all the time, but sadly many times gets overlooked. Keep making things better! You’re doing a great job! Also, thanks for the explanation portions, even building the models, which was obviously overkill. It’s very educational, even for an old dog like me.

Vehicle lift tech here. This is the same mechanism as the chain over ram in your 2 post lift. Its done this way to get twice the lifting range out of the same size ram, for packaging reasons. Im glad you got lucky with the fire. I believe powder extinguishers are more dangerous than not having one because they never work. I use CO2

[@dimetrekorsikov5643]

Anything can be fixed if you throw enough money into it. But heavy equipment can become a money pit way faster than you realize. I've gone through the same ordeal with a cat forestry rig. But the horrible thing was, it was brand new. $135,000 worth of brand new. At first I couldn't work long enough hours to handle all the jobs that were coming in. I mean i literally was working from sun up to well after sun down and even into the wee early hours the following day just trying to keep everything on schedule. The smartest thing we did though was pay off as much as we could while the money was there and not wasting the profit on things outside of the business. But after like 600 hours, it was one thing after another, and cat warranty paid for the majority of parts and labor, but you ain't making money while it's in the shop, but those payments are due no matter where that thing is sitting. After about 1200 hours we were about half way paid out of the loan, but the shop time was getting more and more frequent. And then after two years the warranty on certain parts was covered by both parties and if they had to send a mobile unit out to repair, they wouldn't pay for the drive time of the mobile unit. That doesn't sound too bad, except it was $600 dollars an hour and we're talking pulling hen's teeth trying to negotiate a reasonable outcome. Because my argument was basically, if the work was performed correctly in the shop, my rig wouldn't be broke down in some back woods area that I can't possibly load from. And then when it started turning into where I was paying more of the supposed warranty cost on parts, like $4800 for a rebuilt drive motor, that I had to remove the old unit, take to cat hydraulics rebuild shop , wait for a tech to disassemble the unit, assess the cause of failure, get they're diagnosis, take my bad unit and their paperwork to cat parts, go home install the new unit only to get charged full price for a REBUILT drive motor PLUS the mobile diagnostic was 1800 ...I was done. The honeymoon was over. Three months of filing claims going through arbitration with cat finance, cat tech support, cat district management, cat shop supervisor, cat hydraulics... I'm not joking. Finally ending up at about 50/50 on all the expense. I took in one final time while it still covered and told them every little bit picking thing that didn't work exactly like it was original spec and left it with them for two months. Got it back, parked it, listed it on Forestry Trader and first guy that called bought it two days later, paid off cat finance, and had about 42,000 left over. And it wasn't worth the hassle to have to go that route again. But to make a long story longer, now we buy used and roll the dice, invest in parts and do all the labor myself but they can get upside down real quick and then they're just an anchor looking for a hole to drag you down with them.

Wow. What an education. I don't own this type of equipment but thankful you explained how it functions.

[@kramer00999]

a few decades ago in university the rule of thumb was factor of safety of 10 for lifting or overhead equipment that people are going to be around.

[@js8039]

Nawwww. But you did give yourself an excellent stress test in the last video. Coronary artery disease and arrhythmia are low risks being you made another video this week.

[@BoukeNagel]

Good job. I'm glad you were able to fix it 👍🏻

[@austinadventure]

The effort and detail of explanations of how things work is greatly appreciated, I use boom lifts and fork lifts quite frequently and it was awesome to see the in depth of how the design works. Thank you for showing that, and all the good work you do and taking us along. The cylinder flow depictions are very neat too.

[@dustcommander100]

I can't imagine a better explanation of how the booms interact - and the model was way beyond the call of duty!!!!! Very cool!

[@MusicBent]

Engineer here. TL;DR: the safety factor is ~20 with two cables, ~ 10 if one cable breaks. Maybe half that depending on how quickly the boom can extend, retract, and how quickly it accelerate and decelerates. It’s safe. He estimated the basket + fly boom to be 1200 bounds, let’s round up to 2000. Worse case scenario would be several people plus tools in the basket, with the boom pointing straight vertical. The tension from the basket and fly boom would be 1/2 because of the pulley system, and 1/2 again because 2 chains. So an additional 500 of force from the boom load. Even if one chain broke it would be 1000. Factor of 23. Compared to him saying the chain has a breaking strength of 23,000. This isn’t factoring movement in, which would add a dynamic load. Worse case would be vertical again coming to a sudden stop. Let’s say that doubles the force on the chain. There would then be a safety factor of 11.5. That sounds about right. Interestingly, bolt tension can be calculated to a good confidence without knowing the thread pitch if the torque and bolt diameter are known. (A finer pitch will be stronger as there is more contact area, and also more resistant to unthreading. It also will increase the effect of friction in the equation. ) Anyway, the math behind bolt tightening is MUCH more involved than one would expect. Friction is usually the largest factor in the relationship between torque applied and final tension. I’m fact, 50% of the torque effort is simply used in overcoming friction b/w bolt head and surface, and 40% in the thread friction. Leaving only 10% left to actually providing tension!! Additionally, there is often a 35% +- uncertainty in the friction. Lubricant, dirt, thread manufacturing tolerances, etc. ALSO, the elasticity of the bolt will reduce the final pulling force. Some of these the torque will only work in twisting the bolt elastically , and some of that effort will be lost as the wrench is removed and the bolt untwists. So 50 ft-lbs of torque sounds like a lot, but really it’s not as simple as treating the threads like a simple ramp.

[@FarmCraft101]

Thank you for taking the time to write this. I will add to the description that the overall safety factor at worst case, fully loaded with dynamic movement is 11.5. Cheers!

[@MusicBent]

@@FarmCraft101 Cool! Like you suspected, the boom extension is basically built as safely as an elevator. Just don’t drive over anyone, tip it over, or fall out of the basket! (Not counting that time you rappelled 😅)

[@Seton7588]

Your demo is amazing!

[@yooloo7153]

Thank you for the videos! I really enjoy them a lot. And a special thanks for the model!

[@firstmkb]

It didn’t sound stupid AT ALL. Best advice I ever heard for woodworking was “if an operation feels unsafe, it probably is.” There is nothing wrong with redundant safeties and caution on machines that wouldn’t be harmed at all by snuffing you out.

[@jameshedrick605]

Looks like the wiring in my truck after something shorted out under the dash. I'm currently working on rewiring the truck. I ordered some of those solder stick connectors

[@The-Deadbolt-Deputy]

I love that you made this model. I like knowing how things work. I love the way you break things down to be able to understand exactly how stuff works. This is one (of many ) reasons I love your channel! Thanks for that.

[@daichihayden]

I know your already done with the repair but taping a piece of rope or para cord to one end of the bad hydraulic line when removing would help when installing the new line. Basically just tape the new one and it will help pull the new one back through with the cord. Then you’ll be sure that it is routed the same as what you removed. I learn a ton watching your channel. I’m fairly new to rural life :).

[@ptonpc]

The model was very much appreciated. As for 'boring'? At least it was not a case of "I need a new boom lift because my last one burned to the ground".

Thank you for your effort to make a model. It really helps to understand the mechanical principles behind this massive project. Btw: problems, the various paths to solutions and the final solution makes great youtube content.

[@johnmchardy1229]

As a kid I did this in a test at school. I looked at the diagram and instantly knew how it worked. My brain is able to do that. I really like your channel and learn how to do do things properly. Especially driving a car. Be conscious at all times. Stop or slow down when you can see that there may be a situation up ahead. Better to be conscious than dead.

[@python3574]

The fly boom is not moving twice as fast as the mid boom. They're both moving the same speed, BUT the fly boom is moving in reference TO the mid boom. When the booms move, for instance for 5 seconds, the mid boom has extended 5 ft. The fly boom has also extended 5 ft ....from its rest position in reference to the mid boom. This is because the fly boom is attached TO the mid boom, and the mid boom is attached TO the base boom.

[@lawsondumonceaux124]

I loved the book lifts model. I am a student studying engineering and gear ratios were something we learned about. So cool to see something I learned in real life!

[@jason01095]

[@CarltonDodd]

I learn a ton from your videos. My only tip on the wire repair is that if you stagger the joins, you don't end up with a big bulge in the loom. Did you remove the fusible link from the power lead by shortening it? Or, was the wire basically the fusible link?

[@FarmCraft101]

I don't think it was a fusible link. It just lost connection at the crimp with the ring connector. The other connection that looked burned was a bullet connector. Also there's a 30amp breaker on the other end of that wire when it enters the control box. You do make me think I should consider adding a fuse there though.

[@FarmCraft101]

Actually, after many people have commented that they think it was a fusible link, I'm going to have to take another look. Cheers.

[@johnhampson7]

Really interesting video today Jon, this boom lift has taught you so so much. Keep up the good work.

[@wvpolekat]

The wire you removed to fix the no power problem at the starter is a fuseable link and not just a wire. It did what it was supposed to. Parts store should have them, common on older Fords. Great job with the model!

[@caseysmith1718]

Hi Jon, engineer for a hydraulic hose manufacturer here-its definitely good that you replaced those hoses. The fire likely altered the temper of the steel braid, and may have damaged the inner liner as well. Damage to the inner liner is one of the primary causes of hydraulic line failures. I'm a little surprised those hoses got as charred as they did-virtually all modern hydraulic hoses will have an MSHA rating which stipulates fire resistance. Essentially after being exposed to flame the rubber should self extinguish within a minute or so once the flame is removed. So the hoses must have been pretty old, and there must have been some decent buildup of old grease to really keep things going! Feel free to reach out with any questions!

[@Netbug]

35:06 "It didn't need to be that long anyway" Haha, yes it did... so you can repair it quickly. I leave all of my boat wiring 12" over for just this reason. Also having slack for pulling components out without disconnecting everything is nice. Be it for inspection or to replace something. Nice to see you really digging into this thing and getting it sorted.

[@johnfreiler6017]

Gotta agree. With all the moving parts on that lift, I predict that soon, he's gonna regret just cutting a foot out of that wire. He better order up a bunch of those nifty solder and shrink connectors so he can replace the wires he cut out.

[@FarmCraft101]

I did appreciate the extra length so it made it easier to fix! Thankfully, that harness was made longer than needed because they had different engine options and wanted to be able to handle all situations. I have plenty of extra length. Cheers!

Farmer Jon another 10/10 would watch again. Now to address the elephant in the room, that mortal eternal enemy of the farmer, fire. I seem to remember an older video where you installed a firehose for up close to the house. That covers that, but what if you have another situation or sudden smoke from the wood line. Maybe a water tank with a pump mounted on a trailer or in a 4x4 truck for just such a bad day. Just a thought or a seed of a future project.

[@djtopherau]

I hope you don't take this the wrong way, but I'm somewhat glad you keep breaking things. I say this because, fixing this lift has been a fascinating process to watch, between this and the excavator these are some of my favourite videos on KZbin. I have an engineering mindset and I love repairing broken things, but these are items that the majority of people will never really get the chance to play around on, or see how/understand how they work and its all too unfortunate that in this day and age people are more likely to throw stuff away or send it to someone else then repair themselves. its a lost artform that need to come back.

[@martylost167]

You might purchase a Power probe if you continue to have electrical issues. It connects to power and ground to allow you to just touch a connection and test it for power or ground. It's easier than a meter and quicker. Plus, on old equipment you can apply battery voltage to a circuit to check it.

[@freezerburn04]

“You’re in a tree, suddenly your boom starts going down and there’s nothing you can do about it” lol. Yeah definitely replace that one. Holy geez, guy

[@Artholos]

When I saw the diagram of the boom construction I figured it out pretty quick! It’s exactly the same as a Lego siege tower set I had as a kid, which I was very fond of because it had such a neat mechanism 🎉 Lesson is play with legos and the world will forever be your play place!

[@_aullik]

If you want to understand something like that, look at it from all points of reference/view and it becomes totally obvious. The complex part in this drawing is just understanding which part attach where. If you want to make building models easier, just build 2D models from different points of view (POV), 2 are usually enough, and just build them from card board and a few nails. In this system you just need to understand a few things: 1. the mid boom & telescope cylinder & both rolls are one unit that moves together. 2. how does the mid boom move (hydraulic cylinder) 3. when the mid boom moves what happens to the chain. As the chain has fixed attachment points, look at what happens to the chain from the POV of the mid boom => the top one gets pulled back, the bottom one is giving 'slack'. Both parts of the chain moving by exactly the distance the mid boom is moving. This also means that the attachment block in the chain is moving within the mid boom by the same distance in either direction. 4. the attachment block moves the fly boom. When the mid boom moves by distance X, the fly boom also moves by distance x within the mid boom, thus it moves 2X in relation to the base boom.

[@michelecrown2426]

[@Joel.Ravet88]

Jon, yes sir, I've made mistakes like that... my saying now is "working harder is easier than hardly working." I liked hardly working, until I found out it takes me a lot more time than thinking it all through, and doing it the harder way the first time, because it will be way better than fixing all of the mistakes made trying to do it the easy way. In your case, that was never a thought that would normally cross your mind. Torch the thing thing out, be done in 5 minutes because brute force didn't work. I guess, play bigger, work bigger, and much harder. You're an inspiration, Jon. I'm ready to start using my natural abilities to make my living, time to get out of IT and into backyard handyman work and custom fabrication. You're living the dream there, cheers.

[@flatlander523]

I watched this video yesterday and I am super glad you got it repaired. You are one savvy dude. Although I don't usually callout folks on safety issues, after my foolish use of a step ladder last Sunday and falling from my step ladder when it came out from under me, I feel compelled to say something. My ladder was sitting like yours at 49:13 and I started to step off into my boat at about 3 steps, the 2 feet on the ground slipped and down it went followed shortly by yours truly right on top of the ladder. Bottom line, I had no phone to call for help, I yelled for help long enough a neighbot came to my rescue. EMS to Trauma room; two broken ribs and now laid up for 4 to 6 weeks. Be careful on two legged step ladders and you might look into one of those fall alerts. Stay safe. Ken Davis

[@RobertKihlberg]

I've been following your videos for the last couple of months and found some gems of knowledge in your earlier videos as well. I must strongly complement you on your content and your productions - this video is a prime example. You combine the real world practical work with the theory behind it in a very compelling way! Also, going the length to build models (and even paint them) to further explain what is going on and mapping each critical point from the model to the real thing in a very good way! Very impressive and ambitious! I also appriciate how transparent and honest you are with things not going perfect all the time. Keep up the good work!

The chain is obviously fixed length, when the ram moves any distance X, because the chain is wrapped around it, it takes that distance X out of the chain twice, hence twice the speed. That right there is some Archimedes technology.

This video would be a great learning tool for a multitude of technical classes. Physics, fluid, electrical, mechanical engineering. Just showing repair techs this video would be valuable. Taking the time to create the model was great. Not many other KZbin video would take the time or understand the mechanics.

When i was learning how to sew, and made an error, my teacher would tell me to rip out my mistake. I decided not to moan and groan (because I wanted to very much), and instead i made myself answer “Piece of cake”. This delighted my teacher so much, that I forever say it when I make a mistake I have to undo. It cheers me up. I would like to tell you that you are an excellent teacher and I enjoy watching your videos because I always learn something. You have a positive attitude and I really appreciate that. We all make mistakes and feel bad about it, but telling yourself its a piece of cake to fix, really does help.

Less damage then I expected, fairly easy fix. Just another great video.
