excellent as always Ron and that's the craziest dustpan yet!
Now you just have to make a crazier handle for it.
😆😆😆
We should tell the apprentice to grind it to a point so a handle can be fitted.
Thanks so much, Tony. I didn't realize I was making another dustpan, but I guess it could be. In fact, I could attach a 6-inch diameter vacuum hose to the round end, and it would be self-cleaning!
ooooh do i smell another collaboration ?? shhh everybody hush two top tier humans are about to make a thing !!! may i suggest turning the maho into a hot rod transformer ? :)
I really am taken back years. When I was an apprentice, my master sheet metal man taught me your method to use. Been so many years and I still remember him. So sad he is not with us any more. May he rest in peace. Good day Sir.
My bad for not using your name Ron. Peace
Your sharing what you know, with clarity, helps my life. For most of my 74 years, I have both math laid out & trial and erred patterns for 3d fabrications in glass, wood, fabric or metal. Rollation is a fine gift I wish I'd known earlier. Thank you Ron.
Very good explanation and demonstration. I work in a machine shop with some really smart and creative old timers, might have to blow their minds with this technique.
Cool, thanks
I'm a new subscriber. Being 42 yrs old, any skillset I can develope to improve my craft is a tool I can use to increase productivity and profit for Koontz Machine. That said, personal interest brought me here.
Ron, thank you so much for sharing this process. This is the first time I even seen this awesome technique. I am a mechanical designer by profession and work in 3D in AutoCAD. Some years back I had to design a couple of transitions for the intake and exhaust ducting to the turbochargers of a huge marine diesel engine. The transitions went from rectangular to round and were offset several inches. The shop who fabricated them did an beautiful job.
I'm glad you found a shop that did a nice job. Some shops do better than others!
@@RonCovell Ron, after seven years, I stumbled on this video again. I hope you are doing well and still doing what you do so well. I am still designing and making my own things at home.
Yes, I'm still doing projects, and making new RUclips videos. I have about 80 videos posted so far, so you might check out my other offerings!
Thank you for your generosity!!!
Grettings from Uruguay!!
My pleasure!
Having grown up in a back country shear and break shop I was challenged at the age of 12 to produce shapes out of 16ga. Of any size. Understanding how to draw/draft is a great thing for the mind.
I agree completely!
its a real success and more than that you can teach how to do in 20min. much appriciated.
Cheers!
Completely therapeutic observing your masterful skills.. thank you Ron!
Glad you enjoy it!
Thank you for sharing your knowledge with us all Mr. Covell
You bet!
As an aircraft mechanic I'm always use to being the knowledgeable one. These are some incredible tips and tricks when you can utilize welding thanks Ron!
Great to hear!
Came here because tot but stay for content like this! Great job teaching man!
Awesome, thank you!
Lots of great information. I really like the method of scribing the outside using the inside surface as a refernce.
Glad it was helpful!
Outstanding instruction Ron, thanks so much.
Glad it was helpful!
Really enjoyd the video Ron! I whould like more of them Please!
More on the way!
Nice initiatif Ron. Although i do not need it immediately. Maybe handy in the future.
Thanks for sharing knowledge!
You are very welcome!
A true expert at his craft!
Thank you!
Ron, Thank you again for sharing these videos. You are an inspiration to so many people.. My 11 year-old is really wanting to start metalworking and watches every one of your videos with me..
Sounds like you two are a great team!
You made that look ridiculously easy! Enjoyed watching
Thanks so much!
Great video's Ron! OK, here's a challenge for you. I tried this at work but it did not turn out well! I need a transition between two 6.5" circles at a 90 degree angle. I tried to make two wireform circles welded together and rolled them out tracing the pattern. When I cut and bent the metal, it didn't work at all! I'd love to see what you can do. Thanks for all you do.
Here's one way to do it:
ruclips.net/video/1nStztgcE-E/видео.html
@@RonCovell Thank you for the link. Well, it's safe to say I'd have NEVER have searched for that title!
I'm sure it's possible to do what I want. I just need to make a better model and try rolling it on cardboard backed foil like you did. Thanks again.
I don't see why your procedure wouldn't work. You will have a 45-degree angle at the ends of your transition, but you should be able to pattern it by rollation. It's important that you have matching centerlines on both discs, and keep them in alignment while rolling.
Love all the videos Ron, the collab with ToT was awesome! Another awesome collab would be with Wray Schelin
Wray is great, and I watch all his videos. I would welcome a collaboration with him!
This is fascinating. Instant subscribe
Glad you liked it, and thanks for the sub!
Du, this dude is a BOSS!
super cool video!
Thank you very much!
Thanks for this demonstration on using basic tooling. Could you show how to create a tapered schedule pipe. Eg, 2" sch 40 pipe at one end to 1.6" sch40 at the other over 6"? Is there a method that can be applied by cutting pie cuts in the pipe? Cheers
I have done this with exhaust tubing, by cutting a wedge out, then using hose clamps to pull the gap tight, and weld it. It turns the small end into a 'teardrop' shape, which I hammer round over a mandrel. I question how well this would work with schedule 40 pipe.
Súper perfect thanks!!
Glad you like it!
Very nice!
Thank you! Cheers!
Great video. I have a question.
Why cut and weld the two pieces at the corners instead of the flat sections, like making two "C" shaped pieces?
The key to getting smooth parts is placing the welds where they won't cause much distortion. Flat metal distorts a lot, and it would be extremely challenging to completely smooth a weld in the flat area. You can see how easily the weld smoothed out in the corner, because the contour of the part eliminated most of the distortion.
It's a bit different on thicker metal:

Again amazing hand work. like damn also the way to make the equal parts into 8 that was an amazing prosses and good to know :D damn. !! amazing as always !! Keep it up sir :D
Say, I know this probably a dumb question, but what kind of vise grips are those and where do you get them? I have a bunch, but none of them are nearly as solid as that and I'd love to get a pair like yours.
Stupidly useful video (whole channel really!); I literally have a use for this video and a square to round connection right now! Keep it up!
These are the ones in the video:
www.grainger.com/search/tools/hand-tools/pliers/locking-pliers-sets?attrs=Plier+Jaw+Style%7CStraight+Jaw&filters=attrs&searchQuery=flat+jaw+vise+grips&sst=4&tv_optin=true
That's how you use a divider!!!!!
When you said divide in 8, I assume you were going to split the angle(s) 3 time. divide in 1/2, then into 1/4s then into 1/8s. You way was so much faster
There's more than one way to skin a cat!
Very nice job I'm saving the vid so il have when I will definitely need it may I ask are you a tin basher by trade or a HVAC man
I've never worked in HVAC, so I guess I'm a tin basher. Most of my work has been on cars and motorcycles, with a little other stuff thrown in for fun.
Tidy!!
Glad you liked it!
Fenomensl 👍
Tack!
The other way was how the Russian domes were created..they needed a round roof on a square base!
Do you mean the wonderful 'onion' domes on famous buildings, like in the Kremlin?
@@RonCovell yup! The pupose was to get a round roof on a square base and that's how they ended up with the onion domes.
Good for Apollo XIII
I never knew how much I needed to learn about shaping metal like this. I’ve really enjoyed these!!
Great to hear!
First Tony, now Zep? Next thing you know Jimmy will be here!
I don't know how to thank TOT for letting me discover your channel!
Welcome!!
I’m the same, if it wasn’t for TOT I would have never found you channel. I have learned so much from your channel. Thanks!
👍
Love learning new things from a legend off the internet, what a time to be alive.
Yes, it's a great time to be alive!
Oh, PLEASE!!!
Awesome time to be alive :D
Some people can't afford a small brake but will have a tig welder ?
Watching Ron Covell work metal is as relaxing as watching Bob Ross paint.
I was just thinking the same thing. I keep waiting for him to make a happy tree!
Lmao you hear that Ron. People want to see you bob Ross a episode and weld a happy tree
AIN'T IT JUST AIN'T IT 😎
Everybody needs a friend. 😊
Well I've been called a square peg in a round hole, maybe this video well help sort that out.
I hope it works!
LoL
I love that you've been using relatively basic tools to show how accessible "strong work" can be to us entry level hobby types. I've been imagining a variety of projects to build with my son, working up to something like a skookum electric go cart with clean body work.
I have been a professional metalworker for over 50 years, and I have acquired a shop full of expensive, professional-level tools. I only recently learned that people relate much better to videos that show simple tools!
@@RonCovell What I enjoy the most, is that while high end tools make work easier or less labour intensive, your videos show that even with relatively basic tools, and without too much more effort, I can make relatively high quality work.
@@RonCovell Another fantastic video I agree with many of the other comments, great you set an example of wearing ppe, also the "simple tools" you use to show it can be done without the aid of expensive equipment, and yea that's a crazy dust pan...
Looking forward to the next video ...what ever it may be.
I love that you do videos with the simple tools. But I also love when you show me new ways to use my own expansive and expensive collection of great tools. You still have more. But I'm catching up.
Thank you and your crew for all the work you do making these videos.
Skookum? You an AVE fan? 😉
This is the kind of thing that I know how to do in CAD but would never expect to be done by hand. Well done!
Well, people did make things before computers were invented!
@@RonCovell im a sheet metal worker i would lay it out by triangulation pattern develoment
Stuff like this makes you appreciate the old car fenders with all the curves and lines.
Your CAD can't make it out of sheetmetal.
How do you suppose it was done before CAD?
His voice sounds like the best text-to-speech in the universe.
There is no way in H*** I would have figured that out. Wish I would have seen this stuff 40years ago. I may have had other hobbies. You are a jewel for passing this knowledge on.
"I made a tool to scribe the outside", coincidentally enough it also functions as a bottle opener.
HAH - good one!
Lol
Everything's a bottle opener (if you're determined).
@@mattgies ....how about a pretzel?
....I dare you...... 😄😄
I love how you’re able to:
1) Find an interesting subject,
2) explain it perfectly,
3) build it perfectly - using simple tools no less, and
4) portray it so well in video format.
Talk about being multi-talented!
Thanks for sharing this with us.
Wow, thanks!
Rollation is brilliant, but I was blown away by the scribing part at the end, literally outside the box thinking.
"I have to sorry"
No no wrong end its outside the tube :P
I would have spent ages trying to come up with a way to scribe the outside and ended up with a far worse result. House tool was exceptionally simple as all truly smart things are. I was in awe of the simplicity and effectiveness!
Often the simpler solutions are best!
Love the videos Ron.
Great!
I am blown away by your 3D mind. It is like a musician´s perfect pitch.
Wow - kind words indeed!
Ron, that is beautiful work and your Rollation™ technique is a wonderful tool for us. Thank you for sharing!
Many thanks!
This is such a great tutorial. The pattern and the bending jig made the process so much better, and each were pretty simple to make. Years ago someone told me that fixtures, jigs, and patterns saved time and made things easier, but that hasn't sunk in until watching your videos. So many times I would try to put something together without any of that, and just flounder....or get sidetracked spending more time or money on the tools for the job than the actual job itself. You have such a good balance of that. You're inspiring me to think about the process more. Thank you!
Thank YOU for watching, and commenting!
Ron: And that looks pretty good.
Me: I need another band-aid.
Good one!
I like it Ron, thanks for sharing your knowledge. Knowledge is wisdom, wisdom is powerful. Thanks
Glad you enjoyed it!
Ron, great techniques for many projects! "But wait there's more"! ... " TOT - Dust Pan"! ... Food Processor Funnel! .... Fan Shroud! : )
This is amazing! So simple yet so effective! I've dropped my jaw, I can't find few of my teeth now, but never mind that, I've learnt something new today and that makes me happy!
Wonderful!
Brilliant format of premiering a pre-recorded video & being live in the chat to answer questions! Thanks Ron👍
I'm delighted with all the interest these videos are getting!
Why would a live chat be a better way to answer questions?
@@jonasthemovie Nice for those with fast/proper Internet connection. And you "get it from the horses mouth". Like watching live TV. Or like being married versus not.
Various options, will be (perceived) better, on the basis of individual preferences.
I truly appreciate how you chose to use more basic tools and showcase the process in a way us hobbyists can replicate.
It also amazes me how you can hide those welds so well. Thanks for all you do, Ron!
My pleasure!
This man is the Bob Ross of metal working ans its absolutely amazing
Totally agreed!
“Covell’s Foil Rollation Pattern Paper” sounds like a good product idea to me!
I LOVE it!
@@RonCovell I’d order a roll of it tomorrow - as long as the shipping to Canada isn’t too expensive! :-)
Photo looks GREAT, Ron! Can't wait to watch the master at work.
It won't be long now!
I saw this video going square to round and just had to watch,and I am glad I did.You made this look so easy and the final result was perfection.You sir are a metal magic man and I appreciate everything you do.I have learned so much from you compared to how other people do things,you blow them away with ease.Thank You so much Sir.
You are so welcome!
Your geometric skills and your patience really do pay off handsomely in the piece you have created. Sure was a real pleasure to watch a highly skilled craftsman of steel do his work. Thank you!!!
Thank you so much 😀
Ron is like the Bob Ross of the metal working world.
“ And we just add a little tack here. The fit up is beautiful!”
Thanks for the great videos.
Wow, thanks
Ha!
I just made that comment, above.
I also LOVE that there's no distracting music. We get to hear the welder fan, grinder, whatever....
Great stuff, Ron! Thank you SO much for sharing your knowledge and skills with us!
Glad it was helpful!
Can't wait to see this, Ron! Thank you!
Hope you like it!
@@RonCovell Both the part and video came out perfect! Thank you!
Art!
You made that look so easy. I suspect that my first, second,...fiftieth attempts would not turn out as good.
I don't know if you knew this, but you can use the compass instead of the dividers to equally segment any angle into 2 exactly equal parts. That is if you care about that much precision, just search "dividing an angle" in RUclips. Hope this helps people who don't have dividers on hand.
Thanks for the tip!
holy damn what a nice snips
You remind me of a gunsmith that worked in my shop and his bag of tricks actually it was a wood Gurber chest what fit in the box was all that he needed amazeing how few tools to do a job . 🧐
6:00 Since 8 is a power of 2, you could have just used your compass to bisect your angle a few times.
Easier way to divide a known space like your arc into even segments is to take a number divisible by your intended division count (8), like 16. take a ruler and line up 0 on one side and 16 on the other, mark every two inches and those are exact points to draw your eight lines back to the center.
Thanks for your suggestion. I have tried that technique, and I found that the greater the angle, the more error is induced.
This is cool, makes me wonder though... What would happen if you upgraded your pattern with some Clay that you roll on and let harden and a lip to hold the sheet edges then literally roll the steel onto pattern in 1 motion, then re-bend for springback? 10x speed improvement perhaps.
Well, that's certainly a clever idea. The springback is not a trivial issue, however. I would guess it would take about as much freehand bending to fix the springback as I put into making the bends freehand. Might be fun to try your suggestion and see how well it works.
I'm going to have to remember this when I decide to build my own rectangular exhaust tips instead of buying them.
Never seen it done like that, for smaller transitions this could save time, but for larger I would use true length line method which is what I was taught
You are correct that the rollation method is only useful for relatively small objects. Nevertheless, Iots of people have enjoyed learning about this alternative technique.
Excellent Ron...lets say Linda Goodman we can place round bottle in the square hole...again nice presentation..
Thanks!
Thanks so much for this, Ron! Really clear presentation. You make the information so accessible and easy to understand. Thanks!
Glad it was helpful!
Amazing video! My old friend, little bit age than you, used to tell me: remember guy, when you use the hammer, don't slam! beat the sheet metal
I agree!
“We are what we repeatedly do. Excellence, then, is not an act, but a habit.”

That's a good one - haven't heard it before.
I'm so glad you popped up on my recommendation. This was great to watch and learn.
I definitely subscribed 👍
Awesome! Thank you!
You made a great video and it was very entertaining. Greetings from the V8Lounge in Germany.
Glad you enjoyed it! I gave my first workshop in Germany in 2018, near Frankfurt, and I planned to return last year, but the Covid pandemic made travel impossible. With any luck I may return in September this year.
Yes I hope that at the end of the year it will be possible to travel everywhere.. cool. I'm near from Frankfurt!
Amazing work. My whole live I thought I need "a full metal form and 80 tons hydraulic press" for piece like this :) Your videos opened a new world to me. Thank you Ron.
You are welcome!
I know what that is. What is that? A battery to rocket engine convertor? Yes, that is just a Battery to Rocket Engine convertor. Good Job, should make it to Mars just fine.
You reminded me. The Orbital Sander has been used in sheet metal decades before it showed up at Home Depot.
The German master that taught me called it a 'Jitterbug'. All the new guys had to Jitterbug parts. "Mahtin, Jitterbug some parts, Mahtin', I can still hear him.
Jitterbug sounds way cooler than Orbital Sander.
I learned to call an orbital sander a 'jitterbug' when I was young. Don't hear that much anymore!
This series is AMAZING! ! ! Very ingenious and you are teaching it very well. Thank you!
Glad you enjoy it!
I learned how to do this for my trade. But when he does it, it still looks like magic to me
There's a better way to do this where you can do any size hole to any square there' s no need to make any templates you just need a sheet of paper and work it out by triangulation then transpose your measurements over to a painted white steel sheet with a scribe and callipers, I did this as a part of my apprenticeship as a fabricator in a shipyard, also did a tube into a cone too .
That is a great way to do layout!
I've learned to use your technique by a old HVAC boss 30 years ago. His trade is now gone with computer design. He could build any shape with a ruler, a protractor and a square. Best project I worked on was a Canadian military vessel with all kinds of ducts with weird shapes. It's the way to go when you know math and trig. But for most guys who work in a shop and did not care about math, Ron Covell technique is excellent and does the trick very well.
Wow. I free-hand these, but this is so spit-and -polish. Nice.
Thanks - I'm so glad you liked it!
You call it a success, I call it watching a skilled craftsman effortlessly going about his business! Such a pleasure to watch. Thanks Ron
Glad you enjoyed it!
Awesome video. "I love the smell of fresh dyekem in the morning!"
Yes, it's a bracing way to start the day!
The best piece of advice in this video is to add the 1/4" at the top. I always add at least an 1/8" at the top it always seems to disappear after its bent. I've done these in 1/4" AR plate for asphalt plants.
Yeah - it would be pretty difficult to make this work the way I'm approaching it without having a a little 'wiggle room'.
What a great privelidge it is to be able to watch a true craftsman at work. Thanks Ron, I learn a lot from you.
Wow, thanks!
Thx Ron, I’ve heard about your DVD’s and other creators mention your work, I was really surprised to see your video pop up in my recommendations and the quality of presentation, thought and execution really stands out. Mind blown.
Cool, thanks! I have a lot more videos on RUclips, and you may enjoy browsing through them.
how about laying one out without using a pattern developer ! from a retired tinknocker.
This is ok for toy stuff
I know how to do it the 'traditional' way, but that's well documented in books and on RUclips. Rollation isn't well known, and many people enjoy seeing how it works.
Your a genius man! It's like therapy watching you work. Do you want to be my adopted father😆. Top work 👍
Never was a friend of sheet metal, I can’t believe I am not bleeding after watching the video. Wow you sir are a real teacher.
I don't know why I watch that video I don't ever plan on doing anything like that but it was a very nice watching You make that. Should be outside working but I came inside for lunch and got trapped into watching a 20-minute video by you . Thank you so much sir .
Glad you enjoyed it!
I’m in the sheet metal industry and this here has helped me a lot thank you sir!
Great to hear!
I'm gona say.. 4 big pyramids, tip's pointing to the light's.. & 4 inverted small pyramids...gadzooks!! I've found the Illuminati!!!!!
great diy forming.. thank's..2 bad my Moms 20yrs older..;)
With transitions that look like this I never want to close in another ceiling again!
