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!

[@harrygilbert4593]

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

[@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 🇨🇦

[@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!

[@michaelodonnell7483]

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 👍

[@user-de8fi2ih3s]

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

[@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👍.

[@leomiranda4780]

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

[@sheetmetalwork]

Thanks for the positive feedback Leo!

[@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.

[@outlawpete4636]

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

[@sheetmetalwork]

Thanks!

[@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! 🇨🇦

[@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.

[@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.

[@sheetmetalwork]

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.

[@dominickbisozio]

Thanks for the reply man! Your videos are a great help to me and the people I’m sharing them with 👍

[@ReyErlano]

K thank

[@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.

[@ricsona3194]

Please make more videos I’m an apprentice and I want to learn old school layout 🙏🙏🙏

[@sheetmetalwork]

I promise I will. 👍

[@farooqalikhan8400]

Very good sir drawing nice shape

[@sheetmetalwork]

Thank you 😊

[@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

[@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.

[@Hoyerlift101]

Our shop guy won’t teach. I’m doing this, same process when flat on the bottom, or round is offset…

[@sheetmetalwork]

We've all worked with guys that fit that description. No matter how good they are, they too were once a beginner.

[@samgriess438]

is there anyway to do the collars without the equipment? like using hand tools

[@sheetmetalwork]

There’s always a way Sam. One could use snips or hand shears to cut the exact size of metal, you could then find an object that has a similar diameter preferably a bit smaller,,, with your hands wrap or follow the circumference of this object. This could work with light gage stuff.

[@samgriess438]

@@sheetmetalwork will try! I am looking for one of those Beader and Rotary machines in one. Do you have any recommendations?

[@samgriess438]

@@sheetmetalwork was looking at the Baileigh BR-22 HVAC Rotary Machine Bead Rolling Roller... hoping it can do it all

[@sheetmetalwork]

We have some Baileigh equipment in our shop and for the price it’s not bad. IMO, as for a rotary turning machine, Pexto would be a step up in quality.

square to round and others

[@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]

trace second piece before notching

[@sheetmetalwork]

We often do, place one on top of the other and notch both at the same time. Hoping others can learn from your observation and comment👍

[@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.
