Horse box rear door springs
Please forge a mattress, maybe with pocket springs. My back is killing me.
Surprised you didn’t stack the springs? Springs inside springs my friend.
Who wouldve thought that watching a man make a giant lamp would be so entertaining!!!
How ya goin?
I'd love to see your attempt of a similar project.
Only thing that would make this better is if Alec’s dogs were also out in his workshop
In boots no less. Weird.
Alec stop, you are giving the madman ideas
This spring tension is possibly the most dangerous thing I've ever seen you do, and that's saying something. Attach those suckers really well and please be careful, gentlemen. People die trying to tension their own garage doors.
When designing extension springs, a larger diameter will actually make a weaker spring. For a stiff spring you want a small diameter and a thick wire gauge
I would suggest putting a length of steel cable down the inside of each spring attaching it at both ends. This will prevent large bits of spring flying around if the spring breaks. The length should be the length at fill extension.
(apologies if you are doing this, or if it has already been suggested.)
Safety first!
You MUST attach a counterweight where the springs are so that the springs don't have to do as much work. A large spring like that can cause a lot of damage
Like sudden death.
Quite right 👍
Demonstrably untrue as shown by the original.
You just need to balance the loads correctly.
A counterweight would be a possible solution, but it’s not recreating the original, which is the point of the series.
@@A1BASE But physics says you cannot "just scale up" something. You must do the math before and then build it. This entire project is as dangerous as playing with dynamite. The masses and forces involved are huge and if not correctly managed, can cause major injuries or death.
Take a look at the weight of the one they are building. Do you think that scaling the original lamp by a factor of 7, the final weight of the bigger one will be exactly 7 times larger?
@@A1BASE The point wasn't that springs wont work. The point was that springs which can hold 250 kg at half a meter of extension are extremely dangerous.
I think you should have your base able to be picked up by a pallet jack/forklift. So you can move the finished lamp without disassembling it
WILL this create an anticipated repeat of a "it shal not be named" event?
This feels like a colin furze project. A collab with them would be awesome.
Light at the end of the tunnel
That's what I kept yelling at my screen!
Colin is too busy digging :D
Agreed!
He might need a light@@witchdoctor6502
I would definitely hit up Collin Furze about rolling the metal he has done it a lot and has also learned a lot of tips and tricks.
OMG, I was thinking the same thing, especially after seeing his new pizza oven video where he was also rolling a cone out of sheet metal. coincidence?🤔
I just written the exact same thing....
@colinfurze how close are you to this hooligan that hasn't watched your glorious videos? Can you help him out?
Can't wait for part 23 when Alec finally gets to install the bulb.
I wonder if mrjdesigns (in the UK) is up to a contribution of a suitable bulb?
I think 23 parts are not enough. Back in the days he was blacksmithing a wonderful sword in a few parts and now he cuts a nail out of paper in 47 parts just to present the sponsors. Sorry, but it's getting boring...
Eh it hasn't been that bad these past few videos. I remember at some point it got ridiculous.
I guess that when he was younger he was obsessed with blackmitting and it showed. Now he has bills to pay which changes the projects he takes
@@ehsnils I'm assuming he'll just use the biggest one he can easily source.
I for one is hoping that he at least starts off putting in something like just a tiny LED, or another tiny bulb like one from those electric candle lights for christmas trees, just for the meme of putting a tiny light bulb in a giant lamp. 😆
For both the springs and the rolling of the lampshade, it might be an idea to take a look at Colin Furze. He recently presented an idea for how to use a bit of angle iron on a sliproller to get a perfect cone diameter on your steel, much easier to watch his video than have me try to explain it. He also built a bicycle where he replaced the far with springs, so maybe he knows where to get really strong springs.
Nice , I Just left a similar comment , love me some Colin Furze 👍🏻
Your friend Colin Furze is an absolute wizard at making cone shapes in steel; he even had some hacks/tips on a fairly recent video l.
Ron Covell also does lots of stuff in terms of lighter sheet metal shaping and some of the techniques (former work) might be useful if he doesn't have access to a large enough slip roll.
Use a pneumatic chair spring (or two). They will typically handle 150kg each. It's a compression spring so you will need to make a cradle so the lamp base holds the top and the arm wraps around the bottom. Far safer than regular springs. If you want the "look" then just put it inside an underpowered metal spring.
This is super dangerous. Maybe have some safety straps like a vertical garage door spring would have
This whole project is a death trap. It seems they just blindly scaled up the dimensions of a table lamp, but objects don't scale like that. It's the whole square-cube law principle. When you double all the dimensions of an object, you increase its mass by a factor of 8. Meanwhile, sectional strength is very roughly proportional to surface area. You can't just scale up an object while keeping the proportions the same. If you want a lamp twice as tall, the members will need to be more than twice as thick. It's the reason elephants and insects have completely different body plans. It's the reason tiny animals can routinely lift many times their own body weight or leap many times their own height. Things don't scale linearly. A lamp this big should end up looking more like a cherry picker/aerial work platform than just a giant desk lamp.
When seeing the earlier parts of this project, I assumed they had done all the proper structural calculations, and they just left those out for the sake of the video. But if they had done those calculations, they should know in advance exactly what strength of spring they should need. It seems clear that they just blindly scaled up the original lamp, without any consideration of the actual forces, moments, and stresses involved.
What they are building here is not a cool sword or some giant novelty Thor's hammer. They're building a structure. And they're building at a scale that they have no experience with and clearly lack the expertise to do.
Looking at that frame-spring connection was particularly concerning. They should have started with building the lamp shade, figured out its weight, and then done all the structural calculations from that. What's that bolt rated for in shear? How much force do those springs need to be able to hold on the final lamp? What's the shear strength of the square tube the bolt is passing through, in both gross shear area and net section fracture? On a bolt that long, moment is a concern. All of these things and many others should have been figured out before they even picked up a torch. When you're playing at this scale, you need to do this, unless you want to see you or someone you care deeply for die horribly. They should have done the calculations and then applied a big factor of safety, maybe a factor of 5, due to all the uncertainties involved.
I'm a structural engineer. I have a bachelors and masters in the field, have worked professionally in it, and have taught many courses in structural analysis and steel design. I wouldn't walk into the same building as this death trap they're cobbling together. They are in way over their heads, and they are gambling with their lives. The energy in springs that large is terrifying. If one of those snaps or tears out one of its hanging bolts while you are near it, it will cut through you like a stone through air. If something fails and that heavy steel frame drops on you, you are done. It will crush your head like a watermelon and smash your bones to jello. They are gambling with the lives of Alec, Jamie, and any camera operators or anyone else present but not in front of the camera.
There's a reason buildings are designed by engineers, and that we don't just drop a pile of steel off on site, unleash some welders with an unlimited supply of coffee, and say, "right on boys, go build us a structure!" The calcs are all done and considered well in advance. Plans are signed and stamped by engineers who have degrees in the field, years of experience, and hold a professional engineer's license. That's not to say welding and fabricating aren't skills of their own, they absolutely are. Even just an apprentice welder with a month of experience can probably weld circles around most people with graduate degrees in structural engineering. But when you reach a certain scale, you leave the realm of fabrication and enter the realm of structural analysis and connection design. It's hard to say where that line is exactly, but this project has certainly crossed it.
Alec, if you see this, for your sake, the sake of anyone involved, and for the sake of the families and loved ones of yourself or any of your crew, I urge you to abandon this project immediately. You need to stop, go back to square one, and rethink this whole thing before someone ends up dead or maimed for life. You are playing with forces you clearly do not understand. Cobbling things together is fine at a certain scale, but when you start working on sufficiently large structures, you need to apply the actual principles and mathematics of structural engineering. And the fact that you don't have any idea what spring you need proves beyond a doubt that you have not done these calculations.
You could easily lose a limb or your life, or you easily kill someone very close to you with this project. End this before a disaster happens. Unless you want to be dead or doing your future fabrication with one arm or in a wheel chair, I suggest you stop this immediately. Or, if you simply must go on, make sure you have some really good first aid on site. Think tourniquets and the types of kits used to stabilize the wounds from semi-automatic rifles. If you simply must continue with this, at least make sure you have enough medical equipment on site that you or Jamie won't just bleed out and die on the floor before the ambulance arrives. And make sure you have an up to date will and funeral arrangements planned.
@@TanyaLairdCivil It's just a silly project. You sound insufferable bro.
@@TanyaLairdCivil Wow, that was well written. I really hope he does see your warning. Even without education in structural engineering, you can tell there are so many ways for this to go wrong. Alec, please think about this, take a step back and look at what you are doing. Many of us have been following you from the beginning. We don't want to watch someone loose a limb or die.
@@TanyaLairdCivil That's probably the most thorough thing I've ever read on UA-cam. And your cargo ship is ridiculous.
@@TanyaLairdCivilpost this as a standalone comment instead of a reply so he's more likely to read it!
I feel like calling up a certain guy named Colin who likes to dig tunnels and getting his source of springs might’ve been worth a shot.
You have to know that if you multiply a length and keep proportions on the final product, the volume will grow to the power of 3.
The weight is logically following.
So if you make a 5 time larger lamp, the weight will be 125 times heavier.
Thanks. I was about to post something like this. Physics don't lie.
The square-cube law bites many people who think bigger is better.
And the problem with springs is their strength only increases by a power of 2. (guessing, since their maximum strength would come from the cross section)
5 times the lamp, 125 times the weight but only 25 times the spring strength. So he would need 5 times the spring?
His lamp is going to turn into a molten glass trebuchet.
Correct and if had made the arms out of aluminum.....problems solved
And if you make an 8 times larger lamp with the same proportions, it will weigh 512 times as much
You should definitely just extend the spring mount so it gets more leverage
Springs like that are super dangerous. You might get away with much smaller ones if you put a hydraulic piston/ram inside the spring. By the time you add piston 3 in the opposing position it should hopefully hold position if sized right and increase the holding power by a lot more than just springs. Since it's so tall you could just make them fully hydraulic if you prefer. That would allow you to move it up and down without needing to get in a ladder. Just an idea. Loving your channel!
I've been watching Alec for years now. This is the first project where I've been cringing with how unsafe everything feels. Someone is going to get hurt...
I feel like some sort of hydraulic would be safer than trusting a huge spring like that haha but then it wouldn't be the same i guess =\
thought exactly the same. and 'hydraulic operated lamp' sounds badass
Yeah messing with garage door springs is a veeeeeeerrry bad idea.
No need to die to a spring. Using a closed hydraulic system like you see on heavy equipment tilt deck trailers could work.
Ok
Or could use gas springs, that's what I usually use for that kind of application.
I know he’s busy digging a tunnel but I’m honestly surprised that building something like this and this big of scale that Colin Furze isn’t a part of the project!
Dear Alec,
Please take this in good faith, I am writing this out of an honest concern for your safety. I know you have put a lot of love and heart into this project, but there are times that blind passion will get you killed, and this is one you have stumbled into. I've long watched your work and I love the passion you put into your projects. You are truly a model for a whole generation of makers, DIYers, and people learning the joy of building something with their own hands. So please, realize that this dire warning comes from a place of love and kindness, and out of a genuine concern for your safety.
This whole project is a death trap. It seems you just blindly scaled up the dimensions of a table lamp, but objects don't scale like that. It's the whole square-cube law principle.

How much force do those springs need to be able to hold on the final lamp? What's the shear strength of the square tube the bolt is passing through, in both gross shear area, yielding, and net section fracture? On a bolt that long, moment is a concern. How about fatigue? All of these things and many others should have been figured out before you even picked up a torch. When you're playing at this scale, you need to do this, unless you want to see you or someone you care deeply for die horribly. You should have done the calculations and then applied a big factor of safety, maybe a factor of 5, due to all the uncertainties involved. But again, I do warn you, do not expect a safe design to look like a big desk lamp, its relative proportions will look more like a cherry picker, bucket truck, man lift, all those types of devices used to lift workers safely to tall heights.
I'm a structural engineer. I have a bachelors and masters in the field, have worked professionally in it, and have taught many courses in structural analysis and steel design, and I'm currently in the final year pursuing a doctoral degree in the field. I wouldn't walk into the same building as this death trap you''re cobbling together. You are in way over your head, and you are gambling with your life. The energy in springs that large is terrifying. If one of those snaps or tears out one of its hanging bolts while you are near it, it will cut through you like a stone through air.

That's not to say welding and fabricating aren't skills of their own, they absolutely are. Even just an apprentice welder with a month of experience can probably weld circles around most people with graduate degrees in structural engineering. Again, I'm nearing completion of a PhD, but your fabrication skills, even from back when you put out your first video, likely put my present ones to shame. But when you reach a certain scale, you leave the realm of fabrication and enter the realm of structural analysis and connection design. It's hard to say where that line is exactly, but this project has certainly crossed it.
Alec, if you see this, for your sake, the sake of anyone involved, and for the sake of the families and loved ones of yourself or any of your crew, I urge you to abandon this project immediately.

And make sure you have an up to date will and funeral arrangements planned.
Again, I don't say this to fear-monger or to derail a project you clearly are having a lot of fun with. I've enjoyed your videos on this, catastrophically unsafe as they may be. Your joy and passion are infectious. So it is not lightly that I give you this dire warning. I am not personally involved in your project, so I have no skin in this game. If it fails and kills someone, it will not be may name on the liability lawsuit. But still, the most sacred duty of the engineering profession, before everything else, is to protect the health, safety, and welfare of the public. This is found at the top of every engineering professional code of ethics.
And while I personally have no connection to your project, I do feel I have the ethical duty to throw up a red flag and at least provide a warning when I see something that, within my professional experience, is a disaster waiting to happen. This message is that warning. If I hadn't written this, and something did happen to you, I would never be able to forgive myself for not at least doing this. As much as anything, this warning is so I can sleep at night if I later hear something has happened to you. With this warning, I have done my duty, and my conscience is clean. From here on out, this is on you. You have been warned.
If you do want to continue this project properly, I urge you to get in contact with a licensed structural engineer in your area. Get them to run the proper calculations and prepare a set of proper drawings. And they'll be able to tell you exactly what size springs you need for the project. I would offer to help with this myself, but I'm not licensed where you are, and my own studies right now do not allow the necessary time.
Please again think about all the people you know and care about. Think of what they will experience if you are killed in this project. Think of yourself. Think of how your life will be forever affected if you lose a limb or are paralyzed from a failure of this thing. Think of your audience, and the kind of example you are setting for the thousands and thousands of young minds who are getting into making and building from watching your videos. Know again that I give this warning from a place of love, and I truly do wish the best for you and all those on your team.
Thank You,
Sincerely,
Tanya J. Laird
Replying to this comment with hopes of boosting it… I really do believe that Alec ant Jamie need to take a step back and reevaluate this project. This is not worth the very real risk to both of their lives!
You can also use air springs they are stronger for their size than typical coil springs and they include a damper system which would help prevent the lamp from moving too much
Manually adding eyes to those springs is a very bad idea. They are going to snap from fatigue and drop that lamp onto someone. This is definitely the scariest component of any project I’ve seen from you. Otherwise, very sick so far
What about automotive suspension springs? And/or a counterweight, as others have suggested. Also, you should put some sort of big beefy locking pin mechanism on it so it doesn't crash down if the springs fail.
you can put smaller springs inside the larger spring and stackup the strength that way as well.
At this rate, he’ll be lucky to be done by spring.
We can only hope it doesn’t take till fall. Will would have to come back for that.
if we are unlucky, he will be completely done in by the Spring.
Oof
In which Alec finds out why ants can't be scaled up either.
That said, counterweighting the moment arm with tungsten would help a lot.
Counter weight it with anything, hang an anvil from it. That’d be an awful lot of tungsten… lead is cheap AF and easier to find in large quantities … where are you going to get kilos tungsten and I gotta assume it would be prohibitively expensive
Square cube law
I love the Jamie and Alec dynamic in the workshop. Have you guys ever considered doing a "Forgeside Chats?" I think I remember you and will doing a Q&A thing like that before. Always fun to see your projects, Alec! Keep up the awesome work!
In the same way that I'm really grateful that Will didn't get injured by that falling power hammer, I'll be really grateful if nobody gets injured by this assembly. There's a reason that overhead lifting standards are as stringent as they are
Hey, mechanical engineer here. Why not use a counter weights? Same as the big cranes on the working sites. You stick a big block of steel right where you attach your springs, and it will be that much less weight to balance using the force of the springs. And I would say that smaller springs would do for a much safer lamp.
Also if you want the forces of springs to add to each other you need to install them in parallel like you did in the end with the small spring inside the big one, not like when you had them attached to each other at the beginning. Maybe you already know that or figured it out during the process, but I guess it hurts nobody to say it, just to be sure you have the info :)
Keep the good work man, always have so much fun watching you make all those crazy things!!
The spring issue is due to the square-cube law: When an object is scaled by a factor X, the surface area scales by X squared and the volume by X cubed. So weight, which is related to volume, will scale with X cubed as well. And then there is the spring: The spring force will scale linearily with X. So if X=2 the weight increases by 8 and the spring force scales by 2. If you want to compensate (assuming your spring is otherwise identical to the original) then you need your scales spring to have either thicker wire, tighter coils, less turns, or a combination of those three. And even if you got that right the spring would still carry an enormous and dangerous weight, so I see a lot of people suggesting counter weights which is an excellent idea. I would also just extend the moment arm. It's not going to be a perfect scale model anymore, but fighting physics on this seems like a bad idea.
How about hydro forming a giant ball like in colinfurzes channel and cutting it in half for the lamp shade
I was thinking that the lampshade shape was most definitely not a pure cone. Hydro forming sounds very appropriate.
Lol you guys are doing awesome, love seeing you guys work. Alec, you are a ingenious man for trying to figure it out. Jamie you're a funny and smart man for hiding in case it broke up. Keep up the great work.
Car springs should do the job. If there is no suitable spring: you have a forge, a torch and a lathe. Thats enough to make your own spring.
But keep in mind that springs are storing a lot of energy. A huge spring can easily cut a finger of or break an arm or leg when they are released.
This is the Alec Steele we know and love! Can’t wait for the next installment.
What about using car suspension springs? You can get different spring rates depending on the car quite easily
Car springs are compression springs, using them in place of tension springs (or the wildly dangerous torsion springs shown in the video) is a recipe for injury
Today on how to flirt with death and dismemberment, we present Jamie and Alec, messing about with massive springs and free swinging overhead loads!
I have barely any experience with huge springs or lifting heavy loads, but even I was sweating a bit watching you two goof around like that. Physics doesn't play nice with squishy human parts that get in the way of large potential energies as they become large kinetic energies. I'm glad that a banged up anvil stand was the worst thing to happen in this video, because the danger level was sneaking up through the roof while your back was turned.
You should take the smaller spring, and add it to the the larger one from the inside.
Great work! Can't wait to see the the lamp complete
Montage music has been ON POINT this series, Jamie!
"Oh, it could kill us so well" 😂😂 my favorite kind of project
The way Alec is fearless,y playing with fire with these springs reveals a young man who has probably never hurt himself with a spring before!
Doesn’t need a big spring to do bad damage either.
Lunacy. Read some of the expert critiques and warnings in the comments and rethink this project. An injury from this would likely be life changing and could well be life ending.
You guys needs to be so careful around garage door springs. That thing is going to be a deathtrap.
Garage door springs are rotational torsion, may still work but you need to use the spring as designed to get the correct results.
Alec why not just weld/reinforce a counterweight on the end with springs?
this series is absolutely awesome!
The lamp shade and bulb fitting acts as a bit of a counter weight, when it's folded you can see allot of the shade etc is past the pivot point and sits over the springs
Yep exactly
so glad you nested those springs, you could make a plate top and bottom and fit 3 smalls springs inside the big one. Sheet metal rollers aren't to expensive as well.
Afternoon!
Keep up the great work!
Awesome video, I love watching you work through these ridiculous projects. It's great!
I can see the light at the end of the tunnel. Keep having fun. By the way - how is the house remolding coming - haven't seen any video of that lately. Stay safe.
Having jaimie in all the videos like a side kick helping brings back memories.
May be adding a counterweigh + gas springs would be easier and safer. They even make them with adjustable force, but I don't know if it will be easy to found one this big.
On the other hand, just a piece of advice that I have learned designing machines, not exceeding the yield strength limit doesn't mean the spring will not break, the stiffer/stronger the spring is, the sooner it will break (number of cycles, fatigue) with this elongation you are applying in the video. Please in case you want to mount tension springs reach to one manufacturer and explain them the mechanical requirements you need for this application, I am sure they will be more than pleased to help you.
Anyway, super cool project, looking forward for the next episode! I am sure this will come out great as all the projects done in that workshop
Good for you mate. I haven’t seen you do this before, and I’ve been watching since forever. Crack on doing new things!
Posting on my lunch break?? Thanks Alec!
I agree! Dinner time with Alec!
Lunch here for me as well. Nice!
Cant wait for the next episode!!!!
Practically, once the lamp is deployed the lamp arm will be hanging over the base. That would have to act like a sort of counter weight. Also, once the lower segment is raised up past a certain point, the spring force required will be significantly less. You could make it work in certain positions, but do make sure to limit the travel of the segments to a point that the springs can keep the forces reasonably balanced. There are industrial springs much larger, look at those or manufacture them by yourself 🥸
Oh Yeah!!! Thanks Alec!!!
that spring you bought is a torsion spring,
no expanding, no contracting, twisting!
There are two things you may want to consider. One is using concentric springs. It would allow you to use a longer part of the garage door spring, thus putting much less stress on each individual coil because it won't be forced to spread apart as much. Two is testing the breaking point or deformation point of the attachment loops that you created. If one breaks it would be very dangerous. As always, thank you for interesting and entertaining content.
As a mechanical engineer it’s entertaining watching someone who doesn’t know about springs attempt to make something with springs. This is ambition at its best. Good on ya
As a mechanical engineer you should be terrified for their safety
try stacking your springs one inside the other. you would get the same tension but with a smaller footprint andvyou could keep them in closer to the frame. I know you are trying to stay authentic but I would mount a couple of linear actuators with a small reversing switch.
I do commercial doors and loading docks and honestly the best spring would be from a loading dock, they are tension springs and meant to stretch and release a several thousand pound steel plate
I waited the entire time to see the ambulance being called. I cant believe you both werent damaged in any way. Joking of course. I enjoyed it greatly. Cheers from tennessee.
you need springs for agricultural machines. I used some of those for balancing a big 3 meter structure that was designed to move with the wind (and spring back)
I bet you already thought of this but Colin Furze would be able to roll a cone and he has tons of vids where he does it. I dunno how far away from Colin you are but might be worth a road trip to him to use his setup if he is willing. Also Colin has some videos on hydroforming which would be a good way to do the bowl shaped part of the lamp. In short if you know Colin, call him and ask him what he would do cuz I feel like that lamp shade is right up his alley. Absolutely love this whole build too! I think you should do more scaled up builds after this one. Keep up the great work sir!
That is so dangerous. The amount of potential energy in those springs. I am scared!
the larger springs you cut up were torsion springs. they get mounted horizontal then you tighten them with then end caps you cut off to allow to set the amount of force they will try to uncoil with
To roll a sheet metal cone, you need to use angle iron. You should position this angle just behind the upper roller of your rolling machine and snug against one side of the frame. Then, the angle will guide your sheet metal, enabling the piece to pivot around its axis. Ultimately, you should achieve a conical shape.
PS :My apologies for the grammar and vocabulary errors; it's somewhat challenging to translate technical French terms into English
Greetings from France !
Colin furze has the perfect roller to make these cones! Also a sneaky Collab would hit hard too
See Colin Furze for the rolling part. He's got a short on a hack even how to use a piece of angle iron to roll it perfectly (in a sheet steel roller). As for springs.... please get a couple hydraulic arms for a safety mechanism to prevent someone gettin hurt if the springs should fail for any reason. Also... round the edges on that lamp shade so it's not a giant slicing machine of death.
I've been thinking about this, the energy stored in those springs worries me, how about using a torsion spring similar to F1 & 2CV suspension and enclosing it in a tube, much more compact and much less likely to have large bits of high speed steel flying around the workshop...
Next episode.. Making the desk 😂😂😂
Super video 👍
Watching the section with the springs was too scary, those things are no joke.
7:07 incredible Alec moment
I could imagine Colin Furze would be happy to help you bend your steel! I think it is time for a Furze/Steele project!
Could extend the arms the springs connect to further from the pivot to give you more leverage
If you wanted a more compact spring section, you could nest tighter springs inside of the wider springs and still retain a lot of force.
I really expected looking for springs like what is in car suspension. I know they are typically for pushing but they may work very well for pulling heavy weight. Be bloody careful if you look into them. They are not joke when they have tension at all and can easily break bone. Of course what's to be expected from something that absorbs the movement from a literal ton of metal.
Have you considered using a tension gas spring? Similar to the gas spring on your car trunk/hatch but they pull instead of push. They are available up to a few hundred kg force.
Please do pneumatics instead of springs. Way safer and remote controllable.
And about the shade: how about hydroforming. You'll get a fantastic hemisphere. Colin Furze has some good tips for you.
Force leverage calculation for the frame around the pivots then a custom spring to match that and the maximum allowable extension shouldn't have been hard to figure as a starting point. Everything will change with the shade attached though
I would absolutely love to see you do a collab build with Colin Furze. It would be magestic.
Colin Furze recently shared a brilliant tip to help rolling cone shapes. That would definitely help get the clean cone shapes you are needing
My son is doing a set of drawings of that lamp for his Tech Drawing for leaving cert exams. He has them done on computer aswell for the 3d printer to make the parts scaled down
Perfect time to partner with Collin Furze! With all of the tunnel building and hydroforming, he would have just the knowledge (and tools) you would need.
Love the idea lol. Oh, and colin furze has a nice trick to roll angled sheet metal.
Colin Furze might be a good idea to ring for some of that lampshade work.
Stacking your springs as to have one of the smaller ones inside of the larger ones on the same shaft will increase your spring tension. Just a thought. It is the same concept used on carburetors to counter the force from the throttle linkage.
This project would have been an excellent opportunity to engage Colin Furze. The Furz has the steel rolling equipment and experience.
You should ask Colin Furze for help with the cone, he has a motorized slip-roller and lots of experience with making cones. He also had custom springs made when he made a bike frame out of springs, they looked alot more powerful than the ones you had here.
You should try leather working again, it would be great to see some more custom sheaths like you did with the bowie knife.
That Punisher "wait wait wait wait" was spot on!

these two just have to much fun
These guys are incredibly, much more qualified than you might think in comparison to some cowboys out there !
Like everyone is saying, add counter weights (between the arms that you are bolting the springs to would be the perfect place to attach a couple barbell weights).
And try gas struts (like the kind that hold SUV hatches open) when your springs inevetably don't work.
i have like a truck bed door spring or smth that would be the exact thing u need. they are big tension springs that use like 6-8mm thick spring wire and they are not as bulky as what u are trying. I feel like 1 or 2 of those on each side would do the trick
There's spring formula using springs stiffness constant that could be used (F=-kx), there are torsion, compression and tension springs (you are using a torsion spring here), you have an easy lever to calculate the force required to balance those loads. A lot less effort could be spent if a bit of thinkering was done, but I agree, it wouldn't be as fun to watch. BUT on a more serious note, those things are developing huge forces that could seriously injure or kill someone it they fail. As you are trying to balance that lamp, the risk/fun factor in those video are making my butt cheek clench. 😅
Awesome vid!!!
Deadblow Axe please🙏
