I learned a lot from this build - and went on to build a better one! Check it out here.. kzfaq.info/get/bejne/orSYeNB_2KuwiaM.html

Experiments and learning is never wasted efforts Tim. I really enjoyed your problem solving.

That was NOT a failure! It was a far better result than 99.9% of us would have come up with! The majority of us wouldn't even try it!

You dont need a LARGE MOTOR. You need a small third cog to reduce to. In other words, you need a Gear Ratio, and a motor strong enough to turn that reduced amount of required torque. I think its probably very doable at 4:1 or 5:1. I look forward to seeing updates.

Probably the best video I have seen this year. Definitely not a failure.

Definitely not a failure. This would be one of the best small scale / DIY / home project videos I've seen this year. You learned a lot and we learned with you. This was really great. Thank you.

All I can say, it's amazing how you love your dog.

That was really ingenious! Really impressed with your engineering and building skills.

Tim, as always, I sincerely respect your 'can do' attitude and willingness/courage to tackle new engineering ideas.

We love watching your experiments and builds. Been watching for a long time, and enjoy your thought process!

Building a corrugated iron roller has been on my long list of things to do for years now. Thanks for sharing!

I love watching your thought process with these projects Tim.

Beautiful video mate. Thanks for the taking me on the journey, I love projects like this

The tracer lathe was a win in itself. This is one of those KZfaq videos that taught me something. Thank you for sharing.

Thanks so much for sharing your efforts. I've been following the channel for a long while and I'm always impressed with your work. Inspiring stuff, in the shop and in the garden.

You are just a BRILLIANT engineer! I continue to be astounded at what you invent.

Blessings for your hard and honest efforts to invent, and share your success and fails. Ppl like you were part of the industrial revolution.

loving these experiments

I am in awe of ALL Tim's projects, working or otherwise!

It wasn’t wasted. It was a superbly entertaining video.

Mini fails are just hurdles along the path to success. Love your thinking and work ;-)

LOVE your ability to think old school. Back in the day they didn’t always have a metal shop or engineer to go to. I am very impressed and it was a great video. Well done.

What I like about you the best is that you “do” things. Good for you!

The fun and satisfaction of giving it a go, love how you turned up those wooden rollers, there's a lot of work behind the scenes in this video, you could do another one on some of the details. Could you show more of the turning with the square and round bits, thanks Tim.

You certainly did a great job creating this contraption, and it actually works!

Once heard of a famous quote by someone that I can't remember. "Try, fail, try again, fail better." If this is not the perfect inspiration for how to ultimately reach your goal, I don't know what is.

way out guy just made things for me so easy, love you from india

I suspect that you will come up with what will work for you eventually Tim. I love your prototypes!👍

I’m subscribing here just because your “failure” video, it’s amazing.

Maybe not a perfect roller, but I bet it’s a terrific straightener. I need just that on the ranch. All my animal paddocks are covered in corrugated tin and the wind wrecks them, it’s a constant struggle to keep them in good shape. That machine would fit my needs perfectly

This is genious! Thank you very much for inspiration! I've never thought about combination of the ring roller and shaped rollers for this purpose! I think you could made the rollers by aluminium casting which can be done in a backyard environment with ease especially for such simple shapes to be cast.

I don't recall unsubscribing. Glad to find this channel again.

Very cool I've actually been looking for somewhere to buy just those rolled corrugated sheets. Well done sir!

Those wood rollers were beautiful, really works of art!

Well done Tim. You gave it a good shot.

Love experimenting, then contemplating the result then trying again and again, not sure how to solve this one but sure you can find a way

Fascinating! I would have never thought of wood rollers!

Gee you put in a great effort. You are so clever to have built the device. Well done.

I don’t think failure is a word anyone should ever use ,it is trying to figure something out and it is always improved upon till it works ,and I know you can use a cheap little motor with some pulleys and belts to make a gear reducer then the motor doesn’t need the torque , nice job and that’s what I do too ,take a break from a project until revelation comes !!👍

If you don't try you'll never know, but that was an exceptional attempt!

I work for a company that does this by expensive machines every day. You have done well with minimal equipment.

We use what is called tank iron for making mining shaft collars, the metal is softer and does not kink if you run it through a few times to get your desired curl. Newer corrugated iron is more tensile and kinks

I'm proud of your effort bro. Also, I enjoy your style and manner of speaking!!!!

And now you see why they cost so much huh? :) Enjoyed and gave a Thumbs Up also

Got a lot of ideas from this video. Thank you for sharing

You are one true genius, you made it very easy and affordable thing and thats too in wood. ...👍👌👏👏👏

Good Work. The more you try the more you get better. That is how i got better. Every failure is a step closer to get better at what you are doing. The first version is never the best. You won't notice it but your mind now get more tuned into building better things. After a while you will notice yourself how far better you've gone.

Hi ! From California USA ! I see you have some AMAZING candle stick holders in different sizes with the wood you used for this project. The wood grain design caught my eye right away. Beautiful with some stain or clear lacquer... just no steel center 😃 just cut them to different sizes & hollow out the center for a pillar candle. The bulky candle stick holders could go on a fire place mantel etc... let me know what you think ? They WILL be a hot item in your store.. oh.... maybe engraved with some animals or something ? PRECIOUS 💕🙋🏻

To get Curved Corrugated Metal I noted the industry uses two operations....first Form straight Corrugated Sheet...then run the Corrugated Sheet again through a Second adjustable Set of Rollers to obtain required Arch needed!!!! This allows Metal Roofing to obtain/become Free Span Roofs (no Rafters or Roof Structures).....Great Video....Keep Up the Interests

Well done for the effort, time for a rethink.

The shelter is a good idea , but you need to turn the corrigations 90° . Go with the flow .

Thanks for posting, as I learned many many things, very interesting!!

Always interesting to see your new ideas. The problem seems to be the enormous forces involved to increase the curve. This is a hugh stress on the frame and you as you try to turn the handles.

Absolutely brilliant. Well done.

Hi Tim, I’m watching with interest in Australia. I salute your ingenuity and perseverance, well done Sir, Cheers, Nigel 🍻

This is a good start. If you look at commercial rollers the lower pair of wheels are fixed, but jack screw adjustable, in a triangular plate steel frame. Then all you need to do is apply force via bottle jack. It'll take some shimming but you'll get there in no time. As far as input force goes, you simply need a bigger gear reduction. An old compressor motor plus a bit of bike chain and you'll be there in no time. When it's powered you'll be able to make many more cycles thus smaller displacement each cycle. That means even less input torque required.

You have such a delightful voice and a fantastic approach to making things. I adore your work please continue to make such marvellous videos xo

Thanks. For the effort and honesty!

So cool to see your last few videos building toward these bigger projects. I think getting a smooth roll without the kinks is probably down to the rigidity of the frame. Rethink that and I think you'd be there. A few more gears and you could get away with using a fairly small motor

Thanks for sharing the experiment!

Brilliant attempt- I enjoyed watching. I have no idea how to improve it, but good luck with the next attempt.

genious this is absolutley fantastic fren I was looking into how to corrugate sheet metal for a mini niesen hut / iris hut / ww2 hut

GOOD GOING TIM

So the best way is to walk away brush off your hands and your injured self worth and do something you know how to.. Then overnight or a few days or weeks take another whack at it..I watched the guys with all the money to buy the correct machinery make some roofing material.It wasn't done in one roll through but several.Keep after it and thanks for showing us all your wit to go ahead with this project...great job..

I think you are almost there, don't give up‼️👍👍. Vinny 🇺🇸

I liked your video. I need a Corrugated Iron Roller for my project. So far no luck.

The only thing I can think of that might help is heat. You're curving the corrugations across the grain, which is where it's stiffness comes from. You're compressing one ridge, and stretching the opposite valley. The result is many inches difference in length. F'ex, at 36" interior half circle at a 1" ridge/valley will be a total of 6" longer on the outside than on the inside. What you're rolling looks almost 2", which is a whole foot difference. Heat would help ease the expansion and contraction. Though it might damage the rollers...

Fair dues to you for trying you made a great attempt I ve have often taught how to do this as there is numerous thinks you could make

I had the same idea. I figure wood would work ok. I didn’t have the nerve to go through with the idea. I’m glad to see that somebody did.

I immediately thought of the Anderson Shelter.

fine work. My work almost never works on the first go. Fun to watch

interesting idea using the square pipe and pieces of ply around it , might work whell for making a thickness sander too

I used to work for Corus in their profiling division. Curved sheets are/were part formed then full formed within the curving press. The change to peak and valley structure holds in the curve and reduces creasing. Lubrication is also key. It reduced deviation, creasing and splitting. Your design is fine... but: A. Make the form 1-2 degrees more extreme than the formed sheet. B. Roll half sheets: even the commercial equipment is cheaper at 1/2 sheet form factor because it's so much easier. C. Use a pre loaded rope drive and a vehicle winch to rotate the rollers. D. Multiple passes at fractional increases are vital. A 180 sheet on our standard hydraulic units was 5 passes. Only the "beast" that used a pre and process heated system formed them in 1 hit.

My Good Sir, its never a waste..... iam a trained engineer and i would not have thought of using the wooden rollers, Thank you for that

As mentioned below I vote for a geared down solution. And perhaps rounding out the rollers that are missing their nice round bits. That may be the source of your ripples in the sheet stock of the ripples are at a regular place in the finished profile. Great job! And thanks for taking the time to make this video. You are much closer to your goal than you think.

Good effort and an interesting video.

Interesting video. The tighter the radius, the more likely to get kinks. The rolling of the flat bar worked well. How about rolling a few pieces of flat bar to make a set of ribs, then covering this with sheet steel or plastic screwed to the ribs. It is much easier to get the tight radius you desire with such a construction. A less expensive method may be to make the ribs from PVC pipe. You would likely need to heat the pipe to get the tight radius, but you could make a template of the shape then heat and bend to the template a lot easier than rolling steel. Dave.

Fair play for you Tim I said it before and I say it again,there’s more in your head than you take out with a comb,,

Very ambitious project and a hell of an attempt. Thanks for sharing...even if it did wind up in the fail column =)

Beautiful patterns on the turned wood rollers. Make more, finish them really nicely with sealant or lacquer or whatever, and sell them as art pieces to fund the project 😀

You can make gears, is there a way to provide a mechanical advantage to the handle via a chain and gear instead of direct drive? You will have to complete more turns, but they will be easier.

At least you ended up with great looking rollers. Maybe you could use them for rolling corrugated pasta, or as sculptures? The wood grain looks terrific.

If you used aquaplate (which they use for water tanks) it would not have kinked. Notwithstanding how bloody clever to make this. Well done.

I have often found the ability to do most any shop task can sometimes be a hindrance. Outsourcing some work saves time and money sometimes......GREAT engineering there on a tough build... G>

I like that you show all of your projects, not only the ones that went to plan. Great effort. I have seen these planters and large water storage cylinders made of corrugated steel in a circle formation. I am not sure how many pieces they are made up of, however you could use half of one for the roof. If you find a planter/ water container that is 1.2m in diameter you could perhaps cut it up and attach it to two pieces of straight corrugated steel. It wouldn't be the same as one piece but I think it will be an easier option and perhaps more cost effective.

Love projects like this, particularly when someone else is paying and providing the muscle power. Well done! At least we all know how corrugated sheet is curved, in case it comes up in a pub quiz!

Corrugated iron stock tanks (cut in half) must cost less than all this effort. Not that the effort goes unnoticed or unappreciated.

I’m no engineer, but it looks like you can benefit from having a couple of gear ratios, if your arms are hurting and stuff like that I’m pretty sure doing something with ratios and gears would be able to help on that front

I have a couple of corrugated iron curvers. Both of them motorised. One is a very very old set and one a newer set. One thing worth mentioning is that if you do not use corrugated iron that has been made for curving then you will have major problems. There are two types of corrugated iron. High tensile and soft feed. The high tensile corrugated is much thinner than the curving quality iron. In the old imperial system the gauge for curving quality iron is 24 gauge. The high tensile is 26 gauge. In the new money the curving quality is .65mm and the hi tensile is .42mm. You can curve the hi tensile but you can only slightly curve it. The curving quality iron can be curved down to a 350 radius if you have the correct rolls with very close bottom rolls. So you are on the right track. You should check though that you have the correct material to start with. I am in Australia in Queensland where we have a lot of curved roofs. Not sure if you can get soft feed curving quality corrugated in pommy land though. Hope this helps you in your quest. Personally I think you've done a great job with limited materials and knowledge of the subject. I do think though that you need steel rolls to do what you need. You will also need a very rigid frame.

Getting the right profiles is important

You need rigidity of the rollers( like the heavy ones shown on that industrial one you pictured.) Then you also need guide plates to keep the material straight entering & exiting the rollers.

Never, never never never NEVER NEVER GIVE UP!!!!!

Wish you lived in America near Tennessee, we’ve got those trees on our land you could use. Even a bunch of Osage orange and black locust.

I am very impressed!

Ive seen a machine like yours and they had the same issues, in order to solve that they've put 4 rollers on the top and 4 on the bottom and each couple had a bit more pressure on the shit so the stress on the machine was spreaded between all the rollers. It worked really good but it did not solve the curve issiue and worked only for flat pannels It is possible to build a multiple roller machine that the relationship between the rollers is chaning progressively so as the sheet is being corrugated its being curved at the same time, but that is adding way more complicity to the machine and deammand gear and chain system to time all of the moving parts together...

I admirer you effort now i now not to try to roll corrugated steel

Great video! I learned something out of it. :)

That was perfect thank you wow I never even thought about wood !!!🙂👍

Nice job

I wasn't going to watch this. I live in a 1 bedroom apartment in a city with no room for rollers,LOL. but I am glad I did. I loved the idea even if it did not work %100. I was impressed when you switched from steel rollers to wood. so many people only know how to get to no, they never keep searching for yes. You did. I wonder if you could try a different material for the roof. it is brilliant to come up with new uses for pallets. There is a wonderful old book by ken kern titled The owner built home. it is crammed full of amazing old technology for alternative home building methods. On one of the pages was a design for Quonset type homes made from mostly cloth covered frames that were hoop-shaped and the cloth was permeated with a cement slurry. When the cement dried it created a strong roof and walls that was in a corrugated hoop shape. I wonder if you could make some hoop frames and cover them in burlap and add the cement slurry to them?
