Best video ever created on the step by step process of laying out a square to round. Most of the other videos explain the process as if you already knew how to make one. This one really slowed things down and explained it for the beginners. I have a job interview and this has helped me so much. Thank you. !
I'm building a duct for my dryer vent out aluminum. The duct goes over my stairs so I wanted it to be square going over the stairs and be able to connect to the dryer vent on each sides of the stairs. This was incredibly helpful to make the square to round for each side of the stairs. Very simple explanation on how to figure this out. Thank you!
I was taught this method of pattern development as an apprentice in the 60's. More complex developments can be found in the book The Geometry of Sheet Metalwork by Dickinson and I passed on my copy to one of the promising apprentices at my workplace when I retired in 2016. Modern development techniques are done on CAD and transferred straight to a CNC machine which cuts the pattern out ready for forming and has resulted in the diminishing skill levels within the trade in my opinion.
I've been doing sheet metal in one way shape or form for 35 years. The saying " if you don't use it you lose it " Well, we have a job coming up and I haven't made a sq to rd for ten years. This was the perfect refresher to knock the cobwebs loose. You were easy to listen to and you made it simple to understand. Cool vid.
Thank you so much. This is really neat to see you measure using arcs instead of linear marks. Very cool. I'm going to try it with a 10" square to 12" round.
Great video I've been doing sheet metal for 20 years and I've watched some of the older guys lay these out but have never understood how they figured there measurements I'm going to make one tomorrow 😀
thank you - Very well presented & explained. I've got the material - shear - brake and now the knowledge. I'd think anyone tackling something like that would know (or they'd sure learn fast) to add for 'seams' 'again, thank you
best exp U R number one I'am looking for serveral time and lot of channal but do not understand you make me understand in one time so,thank a lot Jeew from Thailand.
They taught me this in my freshman in high school , I took sheet metal and A/C . We made everything out of sheet metal , even bird feeders. Great job on the video
Good tutorial. However, when you set your small dividers from points 3 to 4 @ 11:24 you're not taking into account the stretch out of the round between those points. As a result the 6" diameter will be small and fitting your collar will give you fits. BTDT. We were taught to draw a line that represents one quarter of the actual stretch out of the 6" round. ( 6 x 3.14 )/4 = 4-11/16". Now divide that 4- 11/16" line into your equal sections and set your small dividers to that. I prefer to divide the circle into 16 equal spaces rather than 12, its a little more work, but produces better fit at the collar. I'm really not trying to nit pick, but there's nothing worse than wasting time and metal only to find that a minor mistake turns into a WTF! moment after you form it.
The layout would be done the same way as this…. Only difference would be that the straight lines on the pattern , you might want to start further in on the sheet, as the pattern sides (a-b, c-d) would go down on the sheet, rather than up… Round part would change shape too, but how much would depend on the size, but the act of laying it out would be the same steps

I really appreciate these videos. It's really hard to find this type of content.
Very well presented. Unlike several others on the same content, this is so easily and perfectly understood. Thank you !
This was a great tutorial. Perfectly laid out. I finally understand pattern drafting square to rounds thank you!

Thank you very much for taking the time to simplify this. It's been a huge help.

Currently learning this as a third year boilermaker in Australia, helps a lot thanks.
Remember doing this for vent duct on ships when I was a Shipwright apprentice..back in 1967...
Great lesson. Thanks very much, you made it very clear, unlike my teachers at Trade school!!!!
Man that is the best explanation for this! Thanks for sharing. Hope you keep posting.
Great video I've been doing sheet metal for 20 years and I've watched some of the older guys lay these out but have never understood how they figured there measurements I'm going to make one tomorrow 😀
Thank you for your video. You make every step simple and clear. I learn from you, again Thank you.
thank you - Very well presented & explained.
I've got the material - shear - brake
and now the knowledge.
I'd think anyone tackling something like that would know
(or they'd sure learn fast) to add for 'seams'
'again, thank you
Thank u so much for taking the time to make this video. Thanks to u, I learned triangulation nd how to draw a square to round
best exp U R number one I'am looking for serveral time and lot of channal but do not understand you make me understand in one time so,thank a lot Jeew from Thailand.
I have a SkillsUSA competition soon, thanks for helping me out.
this was the best explination thanks heaps man
Perfect. Just like daughtery and neubecker
Great video, I learned a lot, thanks
This video is the best one I've found. New to this and I look for the easiest way of learning things. Will you do other fittings as well.
You're good at this! Well done
Excellent tutorial!!
Awesome video

Thank You Very Much for this video.
That was awesome. Thank you
This guy doesn’t make it a math lesson, he tells you how to create a square to round that we can all understand
Phenomenal thank you
nice thanks thats really amazing work you are the best!
thank you very much for the video.

Always check the pattern by measuring around the curve with a steel ruler to confirm circumference.
U explained very well sir
Wonderful explanations
Super clear man thanks
Owsome thanks a lot
perfect solution thank you sir.
Very helpful. Can you do a reverse L please
Good video instruction thanks
Been doing sheet metal for a very long time and always can learn news things you taught me
Much appreciation
Thank you. Thank you
Thank you !!
Awesome
Hello sir I need a video where the round is larger then square. The other videos that have it is not in english
Thank you very much for the video
how to accommodate say 3mm steel wall thickness
thankyou
Can you layout a round to rectangle
Say like a 10” hole into a 6x29 rectangle with a height of 6 in
Nice idol!,,triangulate of my house
Is it possible to make a 6”x36” square to 6” round transition that is only 8” tall?
Yes it is, same method just different dimensions.
That's right.
Is it possible to do calculations as well...I'm struggling with N3
Hello can someone do one where the round part is bigger then the square
The layout would be done the same way as this…. Only difference would be that the straight lines on the pattern , you might want to start further in on the sheet, as the pattern sides (a-b, c-d) would go down on the sheet, rather than up… Round part would change shape too, but how much would depend on the size, but the act of laying it out would be the same steps
Noce
Thanks for your video. Can you draw the oval to a round for next video? Thanks
I still don’t understand
Can the round be larger than the rectangle?
Sure can.
Does anyone know if the round part of the flat pattern is itself part of a true circle?
yeah it is, couldn't tell you the relation as i haven't done them in a while
Respect
Sisukas kaveri!
i know its not my place to say but i dunno if u did this right lol
he did
( look at me )
You forgot the 1/2” flange at the bottom and the 1/4” overlap seam on one side to spot weld the 2 halves together lololol
seams are not always added, unless specified. A welded fitting would have none! Didn't forget anything
Why don't you wash all that drawing off of your arms and hands
