WARNING !! This is a long video with an almost continual verbal description of all the steps of the layout. Some viewers just want to see the steps performed with no talking, but there are also a great number of viewers that like and request a verbal description of how its accomplished. Bear in mind, there are as many variations of technique as there are people doing the work, so this in no way is the only way nor is it necessarily the best way to accomplish the task. It is only my way and the next one may even follow different guidelines as well. The job dictates the technique of the fabrication most times.
Because I lay out sheet metal with a scribe it is very difficult to see the lines on the metal with the lighting glare (this isn’t Hollywood and I’m not a super model) so this time the decision was made to go over my scribe lines with a fine tipped black marking pen to make it a bit easier to actually see the work performed. Another variation to this video is that only the mundane steps or repetitive steps are fast forwarded. All the steps from start to finish are shown in real time to satisfy those viewers that have the desire to physically see those steps and hear the reasoning behind them. All others please note the right arrow key will fast forward in ten second increments to allow you to bypass the mono-tonal and boring non-mellifluous narration of the guy talking during the operation….yeah, that’s me.
Considering the slight possibility that this channel may be considered somewhat of a vlog instead of an informative and substantive channel, I feel compelled to add why this video is just thrown in the middle of a real cool series on a minor trailer repair. Here goes. I have an old retired buddy that called me for a favor with the dropping temperatures. He was asked by this older lady he knows to replace her furnace and he, not being well versed in sheet metal asked if I’d drop in and give him a hand. Well you know me, I’ve a soft spot for old women in the country because you never know what kind of cookies, cake or pie may be awaiting a fellow for doing a good deed…..especially if the good deed is saving them a bit of cash when they can’t afford it. So I gave in to the cravings of a starving belly and said yes, no problem.
Seeing that this was going to be a small but interesting piece of metal, I thought it may hold interest for some, be boring to others but satisfying to me. And satisfying it was…nice hot coffee all day, chocolate chip cookies to munch on and a double decker chocolate cake with vanilla icing hot out of the oven for the shop. So that’s the basic outline for an occasional a day in my retired life….as evidenced by the ever increasing dimensions of the overhang at my belt line. So yes, today we will go back to the trailer repair, it only suffering a days delay as a result of this job.
DISCLAIMER: Remember, don’t do as I say or do as I do because if you do you won’t be your own man. However, if there is a little bit of helpful information that can be gleaned by the discerning viewer, feel free to take that info and build upon and improve it and tag it as your own….because after all we are all here for the privilege of sharing fun stuff with others.
SAFETY: I don’t use gloves. You should. I don’t use earplugs. You should. I don’t wear safety glasses. You should. I do wear safety toed shoes. You should too. I don’t wear a respirator. Well, I should have today because we had chili last evening…..
For those brave of heart and blessed with the tenacity to read all the way through….a hearty Thank You !! Because I know is was a difficult task to complete…..and if you are in the neighborhood, stop in for a nice piece of chocolate cake before its all gone.

This is my second video of yours and these are two master classes in a row thank you

Very good and I appreciate your work! Not a lot of people knows how to make duct work these days. Definitely got to appreciate the older generation like you men. I've been in HVAC for 3.5 years and enjoy fabricating and installing duct work thanks to my boss whose been in the industry about 40 years. I'm very humbled about this trade. There's definitely a difference between a craftsman and a tradesman!

Matthew says:

Quick question! Say the two side pieces did not flare equal directions left and right…for example maybe one side the offset was 5 inches and the other side was 3 inches.. now you have 2 different heights on your left and right sides. That much is still clear… but now when it comes to your last piece which side do you measure off of to get your height for the final piece? 🤔

Good job old timer. 41 yrs in the trade and retired. I still like seeing a craftsmen work. I have most of the tools and some equipment so when I do things for family or a neighbor they are blown away that I made it. Ya gotta love that. Just finished my small welding bench upgrade and always looking forward to new small projects.

John Lind says:

38 years here. 💖👍 hehe then installers throw into truck and mess it all up. 🤣🤣🤣

Faruk Mulabitinovic says:

How do you calculate the actual height of the last piece? The only way ive figured out to do is put all three pieces together and measure how long the last piece should be. But its a bit of a hassle and not very accurate.

why the double hem flange ?

Thanks for another great video!

I’m really disappointed that I never learned sheet metal work first before I got into the technical side of HVAC, this is like Greek to me and my brain isn’t wired this way to understand and learn it. If he was pointing his finger and making me do the wrong I’d absorb it and learn but I can’t just watching it. I’d be pretty happy if I could just make a infield transition for changeouts. I can make them but not like this and takes me a lot longer cause I’m just winging it.
