- Another great Tech Eduard Khachaturyan joins us to show how to Fabricate a Metal Supply Plenum From Scratch. Here are some links to the tools in the process:
Folding tool (in New Jersey we call them clip bender)
www.trutechtoo...
I don’t know how they are called we call them “big ass snips”
www.trutechtoo...
In the video I used Midwest brand but true tech tools doesn’t carry them, however they have Malco ones which is also great snips I just like midwest more, fits better in my hand. We call them right snips or red snips but I just realize they called “Offset Aviation Snips, Left Cut” probably because you can make turn only to the left with this snips, when with the green handle ones you can turn only right.

Aluminum ladder can be used anything that has a corner (the old furnace, any old door, new plywood…) but work platforms are the best for me

Awesome job. Good on you for showing off your techs.
I NEVER would have thought of using an edge of a ladder that way....those cross brakes are crisp...that is slick
I can't wait to pull that off at work and act like it was my idea hehe
It’s a great tip
If you have a lift gate I use the edge.
That blew me away, however as an old dude I can tell you, you will regret using your gloved hand as a hammer. It catches up to you over the years. Your skills are amazing, great work very inspiring.
Yeah more than one way to skin the cat I have a really strong pizza cutter you have to do it on a piece of carpet but it works amazing you'll be surprised
Professional make it Looks So Easy.....😅👍. This is REAL Skills
The cross breaks on the ladder was genius. We do a lot of field fab and ill definitely be using this trick. Much easier and quicker than trying to use a bar. Those turned out crisp and clean. Kudos to the installer.
That was great. I've been doing AC for almost 30 years and I've never seen a ladder used as a brake before. Well done.
Dear lord
That was very impressive. I would love to take on a sheet metal apprenticeship.
Who the hell gives this a thumbs down? That’s mad skills right there. Looks like it was done in a factory. Great job man.
Nobody in 2022 because thumbs down doesn't exist.
Probably anyone that's actually gone to school that knows you cross brake in for supply because of positive pressure and cross brake out for the return because of negative pressure. At least they got a cross brake in there...🤷🏼♂️
Thank you to let us know to make our HVAC life's simpler. Sometimes middle of nowhere, farm land, and the supply is too far, so we have a chance to improve our skills...❤
Nice skills for in the field ductwork. Bravo!
Thank you very much!
That was incredible to watch. That’s a man who knows his shit lol
Man this is gold. I dabble in HVAC but scared of the sheet metal. This was cool. Gotta watch again for al those measurements, but this is awesome.
Glad it was helpful!
I loved it. The ladder trick was pretty good. I probably would’ve broken that end cap, but to each his own. Great job. It was very informative for a tech that knows nothing about where to start. I’d say this guy is shop trained. 👍🏻👍🏻👍🏻
Super impressive! I think I might give it a try on my next install. Thanks for the video!
Impressed with how the bends, cross breaks turned out with that ladder trick 👏 👏. Great job
Can't say ive ever seen a plenum done quite like that. Ive never had to build one without a break but this gives me a good idea in a pinch. But, I don't think I could get my lines to be crisp or straight this way lol
Ya I dunno what voodoo he was using when he folded it so crisp like from flat to rectangle
Makes it look easy well done,done alot of transitions now after seeing this going to try and make my own pleniums comes in handy when your doing a night install,3 feet of snow and the sheet metal shop closed.. 😂
I'm going to school and you save me at least an hour thank you for your video
Wow!!!! Absolutely amazing. Much respect for these tinners
No doubt!
The ladder trick is unreal lol
Amazing job! So happens, the Tech has to return and make corrections on the plenum for the Heater Furnace. The City Inspector found a open gap behind the furnace. I'm the homeowner and wanted to know. Also good to know what the Tech has to do. Thanks!
WOW i always wanted to see how one was made and that guy was slick in making it
It is my firm belief that this man is completely Not Human 😂💪🏾🦺🤝
Great idea using two 12" bar benders. I've lost THREE 24"over my career; been debating on buying another 24"...now I am gonna buy 1 more 12 incher.
Thanks, that's cool using a ladder to make the box.
Like it.
Amazing. Thank you for this video. Kudos to the technician.
Using this method tomorrow! Thanks!
That was awesome. I once used a door to makr my bends, it worked. But never thought to just use a straight edge
Great job, Ed! Thanks for the video, it was very interesting!
Glad you enjoyed it!
Thank you Michael.
What gauge metal were you using?
A rubber mallet makes nice cross kinks when using an edge (ladder, wood, angle iron). 👍
For on the fly, ya got it done. Nice
That's pretty darn neat how you cross broke it!
My knees hurt just watching this. Good job.
Especially nice build considering you made it off a latter. Great job!
Now I have no more excuses. 😂
Nice work.
Thanks again!
That’s rite youngster💪🏿 stay at it🙏🏿✌🏿
Impressive for using a latter.
Thank you very much for sharing I learned something new today
Good job even through there was a metal break behind him that the roofers use.
Cc
..but that wouldn't have helped all the people like me who don't have a metal break sitting in the fucking back yard, so thanks for the insight.
That's for aluminum, don't think it could bend 26 gauge metal
Great video and very informative!
Well done 👏 ✔️ 👍
Awesome, a good skill to have for the trade, wished more sales guys understood this. Also wished you had put down total time to fabricate as a glass shop makes these on their CAD/CNC setup in probably half the time and half the cost of the technicians labor. Just saying, it is a skill techs need, because the glass shops are closed at 1 in the morning, lol.
Wow, amazing. If I tried that, I would be gushing blood from dozens of cuts and would have a bloody mangled piece of scrap metal
THANKS
I'm making my guys watch this. They are so spoiled. I'm lead service and an estimator and we have another estimator, we are required to measure the jobs before they go out to the field. They get their plenums made in the shop pre fab/fit, offset transitions as well if needed. One caveat. We sell one brand of equipment so we pretty much know where everything's going to line up with a few pulls of the tape.
That is spoiled. We always have to make everything in the field. I don't mind a day with crapduct.
Nice work!!
Very skillful, great job.
Never seen some one use a ladder to make 90 bends and cross breaks... you sir are a sheet metal wizzard, very nice. Have you ever looked into a Henslers bender? Or you can make a nice folding tool out of two pieces of angle iron.
Thought the same 😂
Nice work.
Nice stuff!
That tin knocking is on point
Impressive nicely done
This was satisfying to watch. Great work! Preserve your body though!
Amazing job...
Very nice!
Great Video! On an Air Handler, is there a minimum length the Supply Plenum must be before a Tee, Elbow or duct? If so why?
I like your veto bucket
Budget “Veto super pack” 😉
would like to see a supply plenum build with an off set.
Very impressive! With no special tools
Wow that's only one piece of duct!!! Good job
thanks
Wassup cuz. 😂
Do you have any videos or know of any video that show how to make a curved 90 degree elbow for an already installed upflow supply plenum.
That’s Art Work If Your With Me ‼️
I have been doing sheet metal since 1979 and the best tool I have bought was a small folding table, 40 bucks
Where can I buy those roll of sheet galvanized steel??
Are there any hand tools for making cross breaks?
What gauge sheet metal is that? I've seen Kleenex that was stiffer.
Very nice, now let's see your drop cheek ell with splitter.
LOVE IT!
How many plenums can you get out of a roll of sheet metal. Here in Houston we normally just by it made already.
Terrific video. I have 0 metal experience but am in the process of designing/building a geothermal heating/cooling system for my greenhouse/gardening business.
I am planning on making my own "air handler/heat exchanger" and am trying to figure out how to fabricate my unit. I guess I would just do the same as you show here except I want a removable panel so I will just need to build an interior structure. I want a double insulated wall so I just need to make 2 of the same box just 1 bigger than the other.
Considering you only used sheet metal, snips and a ladder for creasing and some simple tools for making the bends this should be doable.
Thanks for the video.
Code in Co is you have to use 26ga on residential!so the 30ga metal you are using is to light to work for all applications!good vid tho!
It is a 26ga
Please get a table. My knees are aching watching you lol
Amazing talent. I recommend saving your knees by using a pad though
I would put the cross breaks towards the inside on a supply plenum
You never mentioned the gauge size of the sheet metal?
does it have to be a galvanized sheet? Or can aluminum work?
What you do with the insulation
Sheetmetal supertech. Awesome work
How much would it cost to install a supply plenum, probably not as tall as that one? I need this replaced in my home. The current one there is made out of some other material, flimsy, and now it has come unsealed. I have taped it and used adhesive spray to try and seal it good, but it is not staying. Wish there was a way to add pictures on here. Trying to get an idea of how much is going to cost me to get this job done professionally.
Great job. Is that not 62 1/2? instead of 63 1/2.
Good fabrication 👍👍👍
No break on the cap? I’m in school and was thought to break the cap, so just curious. Also great job!
In this case the end cap is really small and it won’t make any difference, anything bigger than 16x20 you should add stiffening ribs. Will it hurt if you do on every single one? No. Just an extra step and time in my opinion. Thank you.
Eduard Khachaturyan I appreciate the knowledge! Thank you all for all that you do!
Do you need nee pads?
I hope this video was made just to show the skills of this technician and not the normal operating procedure of the company he works for.
What is the thickness of the sheet metal.. can't seem to find what I need.
26 ga
🤣🤣🤣just like a good tinner having to work on his knees
What gauge metal?? (They never say on any video)
He's good
Do you have a metal brake? Things go a lot faster. Used brakes aren't that expensive.
That’s all for shop
when you say slips do you mean s clamps or drive clamps?
"S cleats" and yes he did use a cleats. Also thank you for this video. I made an awesome plenum cuz of it.
@@misterfee6467 glad it was helpful.
Red snips are always right cut tho. Didnt know malco di it backwards.
Red-right
Green-Left
Yellow-Straight
Not trying to take away from the good work tho. Looks good
Impressive....
i guess if you wrap it with insulation you'll never notice all the scratches. but this wouldn't fly in my area. Tin knockers are to skilled here.
You really need an impact driver for self-tapping sheet metal screws if you want to strip the holes out like a serious pro HVAC tech.
Must have used either 28 or 26 ga. to be able to make creases.
Wow. I hope to be that good one day
What gauge metal is that ?
26
Wondered why I could not find Plenums for sale at HD. Now I know....
Working like that on a concrete floor instead of on your feet with a working table and a sheet metal brake on a daily basis makes me wonder how he will make it to retirement. Don't abuse your body, stay healthy.
I agree 100%, but sometimes things gotta get done.
Mark Nmolly very true I have a kneeling pad myself but it’s still rough after an install. Sore till the next day.
Totally Agree 💯👍
Nice.
BUT that is a square tap.
I was taught to make a long sweep (like a cold air return) with an inside round sweep not square.
It's quiter and less turbulent..
Unreal!! Lol
Why not buy a premade plenum?
