Onsite metal fabrication - four-piece duct transition (Mechanical / sheet metal training

[@helliax]

I sadly don't have tree trunks for arms so it looks like I'll be using a different method to bend that metal. This was a greatly informative video, thank you

[@aglmechanicaltips]

I was using this method when I was about 17 and I did not have tree trunks as arms at that time, lol. Give it a shot!

[@curtisbutler3151]

Have been in the trades 40+ years ,great instruction for apprentices. The forward thinking gets them every time. Very detailed, great video and job

As a service tech I dont get a lot of install experience at my main job. I work for many landlords on the side which end up leading to furnace installs. This video by far has been the best to simplify my sheet metal work and make the job go by way smoother. By far the hardest part of a swap out is the sheet metal transition. One thing a guy I work with showed me, when you go to make a 1in fold, take the S-lock to the edge like you did but the take the hand tongs and grab the S-lock to bend it. The S-lock keeps it mostly even and the hand tongs help with the physical hand strength to make the fold.

[@mattenfeld]

This might be one of the best general sheet metal working videos I’ve ever seen. 20 year HVAC tech, used to be residential A/C guy, so always dabbled in transitions, usually had a sheet metal guy working with me. Now I’m union commercial so don’t see too much tin work. Doing 4 furnace replacements and this was the perfect brush up.

[@DavidLove-z2v]

I’m 55 years old and I switched gears from landscaping to now HVAC just jumped into this industry literally last week. I told the individual that hired me I want to learn everything I can about the industry. I don’t care about the pay. I feel blessed to start in installation to learn that first . So as an apprentice I have been putting rigid duct systems like this all week. I have never done this in my life . Have no clue to what I was doing. I found out that an S Drive has nothing to do with computers. Ha! Now watching this is totally helping me making sense as to what I am doing and see the whole picture . I can’t wait to learn more from you. See you really can teach an old dog new tricks. I’ll see you at the top!

[@SubCoolAir]

Very inspiring!

[@Spectre6w]

I’m 45 and just started apprenticing this summer with a small and local Heating and Cooling business! My background is mostly military and some manufacturing experience. So very little trades experience, but what I do know was just enough for me to get through a trial period of a few installs so the team could asses my skill level. Fast forward to today I am studying for my Section 608 exam and learning how to trouble shoot during service calls. From what I hear some companies aren’t having luck with the younger crowd so they are investing in training older guys who have a desire to learn. Congrats!

[@DavidLove-z2v]

@@Spectre6w that’s awesome! Yeah it’s been two months now installing since I wrote that comment and i love it. It got me in shape, lost 15lbs and counting . Most importantly I’m learning the correct way to install the whole system from duct work, air handlers, and condensers. It will be invaluable for when I get into the service side of things in the future. Congratulations keep it up!

And just FYI for anyone who is still learning, I was taught that you can actually use a screen splining tool to create your cross breaks also.

[@robertpalmatier2699]

I learned more about transitions and cross breaks here than i ever knew before. Ty

[@keithlassiter]

Excellent video. Take out from a 67 year old man who once had strong everything and did it all without tools. Problem is, strong men wear every joint out at some point and then even hand tools are difficult to use. Save your joints. The stronger the muscle the easier it is to destroy the joints! Even an Abrams tank wears out and winds up in the scrap yard.

[@TheLandlordPicker]

A whistle in the center of piece of s-lock with a screw. Dang..never thought of that. Absolutely great video. Really appreciate the information.

Thanks for the help, love your videos! My foreman always told me don’t be the guy who finds a reason why we can’t get the job done, instead be the guy who always finds a way to get it done correctly and hopefully, safely, and you’ll always have a job.

[@gilmarcosta9430]

"We the people" appreciate these videos!

[@Southpaw-qc9gh]

Great info, I call this the trace method and it works everytime. As long you mark it true its turns out great fittings. It’s funny how the terminology is different amongst regions. I’m in the Chicagoland area and we call it S cleat and the tongs hand seamers. Great video brother 👍

[@GeorgeRadocaj]

This is probably the best video I have ever seen on making a transition! Doing a square transition isn’t too difficult, but the multiple angles can be challenging. This will help me out. Thanks!

[@BruhtherKyle]

Awesome lesson and you gave a bunch of cool tips that I never knew. Could you do a video on making offsets, 45s, or 90s out of square duct in the field? You definitely earned a subscriber!

Been a commercial guy for years but never learned duct trans, you taught me a lot so in return I hope I can teach you that carrying a carpet roller for those cross braces can save ya some time.

[@tomsimpson7994]

Thanks for making this, changing out my furnace and this is exactly what I need.

[@TakisMantas]

Another great video Andrew. Thanks for sharing. One suggestion on making the cross bracing. I have made a tool by taking a screen door cord setting tool and replaced its wheel with copper pipe cutting wheel. I put a ruler on the sheet metal and run the wheel tool. It creates a nice crease on the sheet metal and saves your hands by not having to hit the sheet metal. Works wonders when you don’t have a brake.

[@edjay395]

A flat screwdriver and S cleat on soft surface works great also

[@throngcleaver]

Hilmor makes a hand brake with two wheels, but they are expensive. I'm going to use your idea. Thanks!

[@RussellSaiz]

Great video Andrew. It was put together very well.

[@kiefboss1729]

As a sheetmetal trade instructor, I can tell you with 98% certainty that your bulldog snips are called so because their historical predecessors are called bull "nose" snips, due to their short and stout look relative to the long handles. The semiround shape of each blade looks like flared cow nostrils.

[@aglmechanicaltips]

Hell yeah, thanks man!

[@anthonymilanese8372]

Idk I kinda heard a bulldog breathing heavy as soon as he started cutting the metal

Thanks for the demonstration, I’m having to do customs transitions for my new ductwork. The previous people had used 14” insulated flexible ducting with the most insane multi-reduction steps to more flex duct. Rodents made a real shit show of the entire thing … they used it for both the return & main trunk. I really liked your advice for adding cross brakes with angle iron or 4x4 to increase rigidity. I think this is a great video for anyone trying to DIY or even newer guys in the field who haven’t had to do this yet.

[@beeman1885]

Great video. Takes me back to my dad’s sheet metal shop that I practically grew up in. Transitions were always shop-made with Pittsburghs, but he did all large commercial work - no one-day jobs. And we called them Bulldogs back in the 70s as well. That must date back to at least the 50s when my dad learned the trade.

[@oldcarpenter2372]

Thanks for sharing! For making the cross breaks in the field I've seen mechanics use a window screen spline tool, with a metal wheel. With a lot of downward pressure, following the s-lock from corner to corner with the wheel will make a creased bend. This needs to be done on a soft surface like a layer of cardboard beneath the metal. Another guy used a pizza cutter wheel the same way.

[@JohnniePokemonNj]

That’s how I learned to do my transitions I have a 3ft break on my truck that I never use I have a 18 inch and 24 inch bending bar and 6 inch straight and 45 hand seamers and I have the pocket break to put breaks in the metal if the metal is long enough to have a chance of popping when the unit comes on I can have that connected to the unit is about 30 mins. I cut all my slip (s lock) with the Milwaukee m12 bandsaw fast and it does not dull out my cutters

[@ONESNZER0S]

Masterful, thanks for the education!!

[@johndavidson5564]

had to bend 24 gage to make end caps just a trick, use the s-lock bending method AND hand brakes makes a clean edge and easier on the hands.

[@williammarik6159]

Andrew. Glad you are posting again. These old school methods have been staples in our 4-5 hour changeouts. S-clips are critical for a straight edge along with my Stanley tape measure. Also we would use a door in the basement to break our metal transitions. In and out installs where you and your partner would clear $300 each. Awsome Bro !

[@סמדרמלכי-ד3נ]

thank you man ! Great video! so many techniques in one video

[@mrcrowe1848]

6:17 those are regular pattern snips bulldogs are much thicker and shorter on the blade for better cutting leverage

[@BangBang-fj5tv]

[@johnschmitt7971]

To cross breaks in the field I use 2 S cleats about 1/2 inch apart then use a metal screen installing roller to run between the 2 points

was pretty excited to see a new video up good explanation. I'm definitely stealing that s-lock cutting trick. Was hoping you knew why we call them bulldogs lol.

[@hediervarelamedina987]

the video is respectable but hardly anyone talks about the caliber of the sheet used. They show tools and much is said about how to make the transitions but little is said about the caliber of the sheet they use, 24 or 26 caliber is used and another detail is that if or if you have to use a protection system, glasses, gloves at least. For the rest, as I already said, the video is respectable.

[@edo8013]

Thank you

[@cerndo]

Jack Reacher is a tin banger...who knew?

[@tomsimpson7994]

one way to prevent the S lock from bending out is pre drill with a small bit

[@aglmechanicaltips]

True, I will screw the slock in weird scenerios, I just make sure the screw goes all the way through.

[@mikerefrigeration5736]

Just an idea- it would be neat to see a video of you showing how to duct modern day equipment. For example slim duct mini splits

[@JohnSmith-us2ru]

I fold 2 one inch side lips on 2 pieces and leave two pieces flat and slip up the lips and slide the flats into the slips. And i measure off the walls or a leveled straight edge. If someone saw me holding up an overcut piece of metal up to a duct and making dot marks, i would have to unalive them on the spot so they couldnt tell anyone.

[@stacyseguine8904]

I usually put a 4” S on the duct. That way I can make the whole fitting, install it, slide the furnace/fan coil in underneath it then lower the fitting. Also, it’s easy to avoid the “whistle” he’s talking about with longer screws. You get a feel for it after a while to suck in the back side. Not a bad video, clean work. Just not anywhere near the fastest way to do a nice job.

[@androslive]

Great Videos! Would love to see how to do this with ductboard. Most of the properties where I live are 1.5" board.

[@JohnniePokemonNj]

I hate ductboard so hard to connect the metal to it. One way I do it is I make metal lips 2 inches high and I slide slip on the end of the metal lips and take a piece of drive on the inside of the duct board and screw it together so it squeezes together and let’s me have a way to connect my metal transitions to
