Made that adapter, bosses were impressed... said "you found a way to put the square peg in the round hole", lol.... they bought me a t square and a set of compasses and dividers :)
Thank you for this guide. Guide is precise, simply stated, and articulated well. Now I have to adapt the transition to make it into a downspout to pvc pipe adapter :)
thank you, so far I'm making up differant plans you've shared on my lunch hours.... done the square to round, sloped roof jack, and a pyramid. Pyramid is hard to bend in the pan break especially once you add a riveting flange, how small i made it didnt help, used a post note as the base in my sketch lol... going to try an inverted version of the last square to round next, a large circle to small square, than maybe the tee pipe work :).... I'm a fabricator for a commercial roofing company, making downspouts, gutters, and various other trim work and conductor boxes... I've made some intricate stuff in the past, but never had anyone to learn metal design that involved triangulation or parallel line development. Had one old book that got into some of this but it was hard to follow when you've never seen the principles in action and don't understand the terms.
If you decide to make a square to round with a larger circle than the bottom rectangle keep in mind that the pattern will have a tendency to go downward instead of curling up. And on another note making patterns for conductor heads and gutter mitres,,,that can complicated parallel line stuff 🤔. Keep up the good work!
@@sheetmetalwork we've always found simpler ways of dealing with piecing gutter together.... the face of our gutter is a 70 degree angle followed by a 20 degree to make the second segment of the face parnell with the back.... the 70 degree sits an inch further forward from the bottom starting point so for a 90 degree corner I simply drew a 45 degree acrossed the bottom then from that point marked straight up the 70 degree slated segment, than from that point marked and inch further, connect the dots and cut out... than make a mirror image pc, one of with needs to have riveting flanges added) and that create the corner without any drawings, we've had more complex gutters but could aways figure out what series of angles and dimensions were required to make them meet without proper geometry drawings to help.... but you can't trial and error a square to round without some kind of drawings lol, not knowing how to do triangulation or parrel line drawings limited my potential considerably and your channel has greatly increased the scope of my abilities
This video saved my life haha thanks man. Before I was just trying to draw out an arbitrary curve with the length of the circumference, divide the circumference up into 4 sides, read the angle made by the first side directly below the middle, and then repeat that until you have 4. Not sure if that works at all after seeing this video, so thanks.
@@sheetmetalwork Got it, thank you. Does this method work for circles that surpass the bounds of the base rectangle? For example, a 20"x10" base with a 15" diameter circle placed in the middle.
Hello Duane. I've been loving these videos of yours they are most helpful. I sort of do a square to round a bit differently by scribing two arcs as though I was marking out a cone. The smaller of these arcs shares a total length with that of the round finished part of the sq2r and the larger arc can be stepped off with the size equal to the length of the sides. There's quite a bit of maths involved but I find it far quicker in the long run.
@@norvegicusbass not at all. Lol I enjoy short cuts just as much as everyone else. But like another subscriber said, in order to appreciate the shortcuts, one needs to have done it the long way many times.
Excellent video, Interesting subject, The transition from a larger square to smaller diameter round I can understand, but how would you transition from a 14" x 10" rectangle to a 12" dia round offset to one side. I ask because I have come across this and ended up just building a square plenum on top of the unit and placed a 12" collar on it. It looks nice just not as professional, or probably as efficient, as I would have liked...Thank You...
I love the fact that you know that it can be done, but better than that it would look and perform much better. Warren, I will eventually get around making a video for an off center Sq to Rd.
On the first step where he draws the circle inside of the square, you would just offset the circle so that the edge of the circle would fall on the edge that you were needing to offset the round to. From there its just triangulating your distances like he showed in the video, accounting for the differences you specified. For simplicity I would do the half plan route so you only have to deal with one 14" side and one 10" side at a time, then you can use that piece as a template for your second piece.
Is it possible to map out how a cylinder blank would need cut to fit atop a pyramid? Then to make things harder, how to mark out a circular opening at the top of a pyrimid blank?
Hi Duane. Very helpful at this stage. Please can you assist with a OFF-SET RECTANGLE TO ROUND WITH 60 DEGREE PIPE SET? Doing prep for trade test in 3 weeks. Thank you
I haven’t done much for two years :( simply busy with other stuff but if I find a way to get back at it? What size rectangle and diameter and how much offset?
Thank you for replying. Base> 305 x 353. Centre line, 155 & 142. Pipe Dia 188. First pipe length 200 and offset length 195. Off set is 60 degrees. All dimensions in mm. But I will scale to 1:4. Thank you so much. You dont have a whatsapp number? Just easier?
Can this formula also be used if the round is larger than the square ? For instance, I need to make 5.5" square to a 6.0" round. It will be approximately 5.5"-6.0" tall.
You sure can, it’s exactly the same. Your pattern just won’t curl upward as much as mine did in the video. The reason is that your square perimeter is 22 inches and the circumference for the round is approximately 19, this means a slight curling upward. Hope this can help?
The best explanation I have been finding on internet.
Thank you very much

Another great video. This is gonna raise my pay for sure bro. Nuff respect
Using these principles, I made a pentagon to circle adapter. I can't think of an application for it, but it was fun to make, lol

There are plenty of short cut methods out there, and they work fine, but not as accurate

I agree. But, First a beginner must understand the long way if he is going to appreciate short cut methods.
To be honest the maths often deserts me and I mostly resort to the method you lay down here. I didn't mean to come across as a dick.

Thank sir, it work
Quick question, what if the circle is bigger than the square. Would it be same type of formula ?
Layout procedures are the same, but expect your pattern to curl downward.
Are the steps the same if the diameter of the circle is greater than the length of the square?
Yes they are, the only thing that will happen is the pattern will curl downward rather than upward.
How do you handle the overlap on the seam? It doesn't seem to be in the pattern.
I did leave out the seam, great observation👍. I do have a tendency to do that because of the various types of seams.
