Triangulation - Square to Round, fabrication

[@FireandFrostHVAC]

There is so much bad info on KZbin and then you come across a gem of a channel like this one. Clear, concise, & correct. Thanks for helping a refer mechanic sharpen up his metal shaping skills.

[@sheetmetalwork]

Thanks for taking the time to add your comment, very much appreciated!

[@mthigh33]

Followed this step by step and made my first ever square to round! Boss was impressed. Tthank you very much sir!

[@sheetmetalwork]

That’s awesome! I’m happy for you.

[@harrygilbert4593]

Great great job. Your bringing me back to 1999 when I started in the Trade. Keep up the great work. Thanks

[@henrychacon3277]

You did a great job. I was forgetting how to make one and then you appear. You are a great teacher. Thank you very much.

From one tin knocker to another, great fabrication. Much appreciated!

[@sheetmetalwork]

Thanks!

[@barnzYT]

Very nice craftsmanship and a good teacher! Continue to be a master of your craft

[@sheetmetalwork]

Thank you! Cheers!

This video made my morning. I havent made a square to round in probably 6 or 7 years. Couldn't find my Richard Budzig book. Built a 14x20 to 24in round fitting. Came out awesome. Now i need a beader and a spot welder for my new shop.

[@sheetmetalwork]

Your comment made my night. Thanks Micheal 👍

[@nathankoroush7918]

I haven't had to hand lay out a square to round in over 11 years, but yesterday because the plasma table was shut down, from air compressor. I needed this video. thanks

[@sheetmetalwork]

That can sure happen! And when it does, it’s the skilled worker that steps up to the plate👍.

[@johnbagewll2321]

You are very talented and thank you for the tutorial.

[@sheetmetalwork]

I happy you liked it John, Thanks!

Excellent layout and step by step I am a retired US Navy welder sheet metal pattern maker I learned something new thank you Best to you sheet metal worker

[@sheetmetalwork]

Thank you

[@brisson182]

Awesome video! Thanks a bunch! I haven’t done this since college and might need to do it as part of a skills test for a new job. Cheers! Keep up the great videos

[@sheetmetalwork]

Thank you! And I hope you end up with the job you want.

[@andygulick6085]

Made my first two square to round fittings with the help of your video. Mine were 6 1/2" square x 8" round. So the plan view drawing was a little bit funky. But it worked fine. Thank you

[@sheetmetalwork]

You welcome Andy, I’m happy to hear that it worked out. With those measurements the pattern didn’t curl up that much. Eh! 🇨🇦

[@leomiranda4780]

Best Triangulation video I've seen so far! thanks man!

[@sheetmetalwork]

Thanks for the positive feedback Leo!

[@nickitsnotcj]

I think your content should replace our apprenticeship teacher. You far more clear, concise, and don’t rush like we already know how to do it. Thank you

[@sheetmetalwork]

@@nickitsnotcj Hello Chris, I’m happy that you find my videos helpful which take time to put together. To be honest, It happens that I also need to rush through classroom theory or shop fabrication. That’s the reason I started this channel and wished I had a demo vid for every concept or skill. Thanks for adding a comment.

[@newfiegangsta22]

Great video! Going to school for sheetmetal soon hopefully! Lots of install experience but very limited in the shop. Was great to see someone make one!

[@sheetmetalwork]

Thanks for your comment. I hope you enjoy school, and if you ever wonder or have any question? Simply let me know and I just might put a video out there for you.

[@JimmyPetrol]

Excellent video. THANKS for making it ! I need to do this fairly often (re-modeler)...and now I can actually do it NEATLY !

[@sheetmetalwork]

Im happy to hear that Larry. Cheers!

[@dexal8368]

Just used this to make my first square to round and it came out perfect!! Thank you so much man

[@sheetmetalwork]

I’m as equally happy as you😀 Dexal, This is the very reason for putting these videos out there. Cheers 🇨🇦

You are the freaking man, TINNER!!!

[@rhiczgartv3410]

Nice lay out bro!,good job

[@DeryaTanbasi]

that's a nice piece!!!! Amazing..

[@michaeljowers349]

I apologize if this has already been addressed in the comments, but what is an alternative to the beaded collar? All I have currently in our shop besides a brake, Pittsburg Machine and a Cleat bender is a Roller and easy edger.

[@sheetmetalwork]

@@michaeljowers349 no need to apologize MJ, if your question is how to fasten the collar? With minimal tools, One option could be to notch a half inch on the bottom of your collar, sorta like a dovetail notch, one notch in one out, then use a few screws or rivets to secure it in place, finish it off with some duct sealer. Another option is to use a pair of pliers to flare out the bottom of your collar so it fits over the fitting, secure and seal.

[@DewateringScrewPress7]

Could you share some light on the equipment used for the same ?

[@sheetmetalwork]

I plan on demonstrating many of the hand tools, bench and floor equipment that I possibly can in the near future. That’s the plan, but finding time is my issue.

[@DewateringScrewPress7]

@@sheetmetalwork Thank you so much for your quick response. I've found the hand press for the same but considering we also have thickness upto 5-6mm thick in SS304 we might have to go for a hydraulic or motorized version of the same.

[@skeezerdog13]

Thank you! Perfect tutorial

[@sheetmetalwork]

@@skeezerdog13 thanks for commenting.

[@kyresearcher]

Awesome job. Nice to see good content... Recon i could get your advice on a simpler bend?

[@sheetmetalwork]

Thank you! A simpler bend?? If I understand correctly, you don’t have access to a bender? If that’s the case, you could form it by applying pressure with both hands over a round pipe, conical pipe even better. In the trade we can also use sheet metal stakes.

[@kyresearcher]

@@sheetmetalwork i have a 18 inch hand bender, but the issue I'm having is I'm trying to make 4x10 floor boots. I don't exactly need to go rec to round. More a long the lines of the rectangle 4x10 down to a pan I can cut a hole into for my 6inch flex. Joins are on 2 foot center so I have room, but have tried for weeks to get the bends right and can't figure it out. Trying to get the pan to work out on the 4 inch side of the boot.

[@sheetmetalwork]

I assume you are installing floor registers in the boots? Again I am not quite sure of the issue you’re dealing with, but hardware stores do sell 4x10 x 6”Rd boots. The 3 most common boots are the Angle boot, the Universal boot and the one I think you’re looking for, is called an End boot. 🤞

[@kyresearcher]

@@sheetmetalwork yes sir, I am just trying to find a pattern to make them myself. But yes, installing floor boots, just wanting to bend them myself.

[@sheetmetalwork]

The patterns for the AB and the EB requires triangulation from an elevation view ( just more steps). You might want to look at buying the one you want, open it up and flatten it out, there’s your pattern. When there’s a will there’s a way :) good luck.

[@drallersouldust3054]

was the circumference division 12 was a standard? or how to find the right amount of division?

[@sheetmetalwork]

Normally 12 for smaller diameters, but the more divisions, the more accurate

[@aloualesly5705]

So impressive. Thanks so much am gonna try that

[@sheetmetalwork]

I’m positive that you’ll get it done 👍

[@Hoyerlift101]

I see it much more clearly. Thanks for showing the unnecessary visual steps, helps. 👌🏼

Thank you!

[@dominickbisozio]

Great video man thank you, I’m doing a competition for my Local as an apprentice and this is one of the fitting I half to make. You explained it the same exact way my instructor did so this was/is very helpful.

Thanks for the comment Dominick, I went to a Local comp myself a long time ago. Congratulations on being selected for the local rep and good luck, no matter the outcome, you’re already a winner.

Thanks Brett.

[@johnnytanguma1126]

I completely understand this going from a 10" x 8" to a 7" circle but I'm having trouble going from a 6 3/4" x 4 3/4" rectangle to a 6" circle. Help anyone please???

[@sheetmetalwork]

Draw a plan/top view of the rect 6.75" x 4.75" with a 6" circle in dead center. Use the same procedures as in the video. Just a heads up, the pattern will be much flatter or should I say, not as much rise. This is due to the perimeter of the rectangle, and the circumference of the circle, are nearly the same. Good luck Johnny.

[@HVAC1actual]

put the seam in the corner. it looks better and won't screw up the S and drive connection.

[@ianbottom7396]

I appreciate your explanations but can I suggest that it would be far easier to follow if the reference numbers, letters and marked lines were done with more visual clarity, perhaps maybe making the references bigger in permanent marker

[@sheetmetalwork]

Thanks for your feedback Ian, I really do appreciate it and I will try to do so on my next videos. The funny thing is that I was taught not to use a marker, only a scribe for better accuracy. I have more years of a fabricator/Installer than I do as a cinematographer 😀 Thanks!

[@ianbottom7396]

@@sheetmetalwork 100% agree on the accuracy of the scriber to do the job for real but to demonstrate clearer markings, larger references would help. BTW I appreciate your videos as I have found yours are among the best I’ve found on this subject (which I’m no expert in)

[@devonking4281]

[@EricLabelle-cj6bk]

Terrible video. Tells us what you’re doing and why. Not just layout the work without an explanation. Every time you do something, ask the question WHY.

[@sheetmetalwork]

@@EricLabelle-cj6bk It is a how to fabricate a square to round video not a WHY do we use a square to round video. If you need to know WHY Eric? Its because this fitting will allow you to connect a round duct to a rectangular duct :)
