Thanks for taking the time to shoot this video. We all know you're busy filming the new Jack Reacher series.
REALLY?😮
LOL!
This guy is a MASTER.
Bro, I struggle so much in the field. THIS guy has answered EVERY question I have. Lol
i just want to know when his next UFC fight is LOL
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.
Whoa I didn't know that Reacher was a tin knocker?! lol All jokes aside, really good video!
Have been in the trades 40+ years ,great instruction for apprentices. The forward thinking gets them every time. Very detailed, great video and job
One of the best how-to videos out there. Perfect balance between subject matter and technique. Very professional. Good job!
Making a fitting on site is a valuable skill. Good job!
A master complementing another master right here!
"We the people" appreciate these videos!
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.
Hell yeah, thanks man!
Idk I kinda heard a bulldog breathing heavy as soon as he started cutting the metal
Спасибо за историческую справку!👍😂
Bulldog snips are the short jaw snips that can cut through heavy gage slips the large ones are hand shears
I learned more about transitions and cross breaks here than i ever knew before. Ty
I'm not a big fan of tattoos, but I have to admit that I like the tattoo on your forearm.
Great video as usual!
You sound more like a Biden supporter.
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.
And everyone has a flat head screwdriver, the wide one in your bag, you know the right one 😉 and a hammer!
I don't do any HVAC, but when you mentioned keeping your drops in one area for easy cleaning, good God I wish you could teach my coworkers that. They're walking pigsties.
This is a fascinating video with real world application. Very well done and thank you.
One of the best sheet metal videos. Excellant job of explaining how and why.
Woha! Thanks so much for the intro to the Malco M14N ! Absolutely gigantic compared to what we have in Europe. Ordering right away.
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.
A flat screwdriver and S cleat on soft surface works great also
Hilmor makes a hand brake with two wheels, but they are expensive. I'm going to use your idea. Thanks!
Master Journeyman. WOW. very nice work in field.
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.
3rd year apprentice here up north, greatly descriptive, and informative! thanks alot! subscribed and will be watching more! i wish my old foreman could communicate like this!!
Everything thing about this guy is great. Bet he was a state champ wrestler at one point in his life.
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.
Fantastic video
Andrew keep it up!
Will do, another one coming out soon.
Very well explained. Thank you!
Phenomenal absolutely phenomenal sir!
Ingenuity at its finest.
Awesome demonstration. I always enjoy your videos.
Really appreciate you mentioning the vertical measurements!
Thank you! Very helpful and informative!!
Fantastic work! Your a great teacher
The fact that you use no ppe makes it more impressive
Really good video. You definitely have some of the best videos online for this.
Thanks for putting these videos together. Very well done and helpful!
Hell of a teacher, thank you sir!
Nice work, great teacher.
Life saver! Diy looking for much needed tips.
Fantastic video.
Thank you.
thank you man ! Great video! so many techniques in one video
Great work guys, thanks for the informative video.
Thank you
That was so well done! Thank you for a great quality job, with simple tools! Wow. Thank you again.
Great video thanks
What a trick, folding the s- lock when cutting multiple pieces!
Thank you!
Thanks man. Awesome video. Well explained.
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.
This is very good instruction. Thank you
great information learn more in this video than I have from the "boss" and his kid I've worked with for the last 3 years
Very good video
great job ,i really enjoyed the time you took out too show step by step .
Wow that is amazing; thank you so much, 💯
Love the channel great content. Thank you for sharing your knowledge much respect from central cali 👊
Great video.
I once saw a guy use a ladder for the markings...pretty cool.
Great video
Incredibly useful, well done, very patient instructor. Thank you. raphael nyc
Really good video thank you
Thank you buddy!!!
I do sales. I was service before. And install helper for a year before that. I always wished i would of gave myself a couple years as an installer before going to service. Installers are next level when it comes to this industry. My hat is off to them.
What a freaking great video/tutorial, everything! I'm glad you tube suggested this video. I'm subscribing for sure.
This is a great tutorial. It would be great to see something like this for a return transition as well. Everyone has their own method; it would be great to see how you approach it. Thanks for the videos!!
Thanks it beautiful
great video thank you.
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.
Yep and hilmor makes one. Called the pocket brake
Очень полезное видео, спасибо за урок.
You have gold hands!👍
Keep crushing the metal 💪 your hands will get there and your forearms will be super buff 🎉
Love your video. I like to watch how other people do metal work always looking for any tips or tricks that I could use to improve my speed and quality of my work
That's why I'm here lol I'm a install tech with 2 years experience an im just trying to learn diff tricks of the trade! Great video sir I'm sharing to my co workers as we speak
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 !
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
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
Use hand tongs with s slide for thicker metal
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.
20:32 Tin knocker!
Just kidding. Thanks for the vid. Field fabrication is what i struggle with most
I got 10 years experience I still love watching other people's way
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.
Jack Reacher is a tin banger...who knew?
I’ve done just about everything to brake except bending it over something pointy
Easier way to make crossbreak is lay your metal down on a piece of cardboard. Grab yourself a s cleat and lay it diagonally on metal, apply pressure on each side of s cleat and trace along w pressure w your folding bar and you got yourself a crossbreak
Great instructional video, thanks for doing it. What gage sheet metal do you use for HVAC transitions?
Most fittings I'm using 26 gauge but if the transition is large I may step up to 24 or even 22 gauge. If the width is under 24" in width you are normally ok with 26 gauge.
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
Great Videos!
Would love to see how to do this with ductboard. Most of the properties where I live are 1.5" board.
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
The best
6:17 those are regular pattern snips
bulldogs are much thicker and shorter on the blade for better cutting leverage
Awsom video, what about the last piece you made up, it didn't get fasten down to the bottom unit? also, could you remove the screws on the bottom unit and just use them to secure the last panel to the bottom unit? This question is coming from a household / commercial mover, lol. I was repairing the shroud and cleaning out my package unit at my place in Pennsylvania, when I was reassembling the unit, I grab the wrong screw and ran the screw into the coil, so I chose to replace the unit because of the age of the unit and the cost of the repair including the R22. So now all I have to do is make the Shroud from the new package unit to the trailer, I was planning on removing some of the screws from the unit and adding the shroud to it. What do you think about that?
A 2in metal screen roller works good to do the cross brace.
They make a hand brake ..goes in ur palm and has two rollers..I fabricate and have learned technician since I started the field installing commercial then went into residential..so a electric professional plumbing tool for brazing and the hand brake is a must along with bender And swedging tool..good job teaching.
I've never seen one but will order one and test it out. Thanks
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.
Forgot to say "seal it from the inside"...
I usually do similar to what he just did but seal from the inside and back out to front. In a closet you'll have to
youre such a fucking chad
showed up on site yesterday as a new apprentice no idea i was working ducting, never even seen a handler before. boss says do this ducting no training just send it.i was pretty useless but everything is seald gotta go do the return today its a strange 180 situation wish me luck. thanks for the info!
Great video! How do you like the 12v Dewalt?
I like it but I still keep a 24 volt impact on hand. It only has enough torque for sheet metal but it is small and lightweight which helps a lot in this industry. Its great as a secondary but get something with more torque if you only plan on having 1 driver.
🔥🔥🔥🔥🔥
Andrew what gauge material are you using? I need to build this for a furnace.
26 gauge in this video, the longer the piece the thicker the gauge needed but 26 gauge should do up to about 22" or so in width.
@@aglmechanicaltips Thank you for your response. Top notch video!
Did you say you mastic over all the insulation? I don’t think I’ve seen that before. And the way a slather all over the place I think it would look bad..but if you do it I bet it’s worth it?
It's required by code in my area to mastic the external seems on the insulation. The climate here is hot and in hot attics the tape fails over time without it.
What do you use that machine in the background? Will it show up in videos?
That's a plasma table. It cuts all of our fittings instead of laying them out by hand. It is shown cutting the steel at the beginning of all the videos. I may do a video on how to run it one day but I have a whole list of other things I plan to get to first.
Window screen install tool is great for making cross breaks. Btw, you should make your cross breaks before bending you lips
Thanks for your teachings, you should check Dean Grazioski or Tony Robbins out for high dollar and up value if your teachings.
But your builds seem to be for high dollar clients. Do you have a video for home owners to slowly upgrade from flex tube to metal conduit? Have done some fix it and builds for Angis list. By son and daughter are mechanical too, just no ac workers yet. This is just so I can upgrade one room at a time, improve my air quality, and maybe eventually replace the 22 year old heater (when needed). Have seen the lines break down and hoping it can be done by hand.
I have never sean a truch carry a bead roller on a truck.you may be able to use a contracter's print tale on site.
What Geothermal unit is that with the reheat coil?
That unit doesn't have one but Water Furnace just released a reheat coil on some of their residential package units.
Called "optidry" www.waterfurnace.com/residential/products/geothermal-heat-pumps/700a11
This dude bad!!!
