[@christophermuhammad860]

Really good tutorials, hope you will keep it up. Hard to find good layout stuff on KZbin. I see the Richard Budzik layout book, which is my main go to. Wish I would have had these when I was first learning triangulation and true length triangles. I will use some of these with my guys in the future.

Thanks Christopher.

Exquisite! I’ve been seeing guys put out videos on 90 degree T joints and I want to die.

[@sheetmetalwork]

lol, thanks!

[@noahoyeah]

So many steps. I went at it. Half way through it and my mind was worked lol.

[@sheetmetalwork]

Step by step is how it should be done at first until we get to know a few short cuts. Working the mind = Growth

[@noahoyeah]

On the throat calculation. 3.14 is 1/8 right. Or is it the 1/16 as mentioned

[@sheetmetalwork]

@@noahoyeah yes .14 is closer to 1/8. Sorry for my mistake 😮… please let me know when you notice another one, they are intentionally placed here and there. 🤪kidding

[@noahoyeah]

@@sheetmetalwork hey. I had to reference a decimal to fractions card I’m no genius let alone know much about fractions and decimals. I’m getting ready to begin learning. Sad I started taking all this serious at 41

[@sheetmetalwork]

@@noahoyeah I’ll put money down that you are going to be a great student, and I’m quite sure your have other skills that will help you along the way. As for the decimal, simply multiply the decimal portion x 16. Your answer will be to the nearest 16th.

You are a PRO!!!!!!

Thanks Bob! Could you please send your comment to my Boss. LOL 😀

@@sheetmetalwork I've been a Retro INSTALLER for 21 years and I never learned the proper way to layout fittings like you! I love how easy you make it seem.

[@norvegicusbass]

Am I right in saying that the other cheek is simply the first one drawn? The one you took the element lines from?

[@sheetmetalwork]

Good question, Yes you’re right, because it is flat.

[@Oxatolla]

Hi Duane. So, 2 pieces to make the heal. How do you join them together at the crotch? Extend 1 heel piece by 1/2" and spot weld? Thanks.

[@sheetmetalwork]

That definitely works if a spot welder is available, if not one could use, something that looks like a standing seam, or even an S cleat on one half and a small flange on the other. I hope this helps :)

[@bcornwall2785]

Excellent tutorial but how do you form the male part of the lock form on the top of the y branch (where the 2 heels meet). I take it that it can’t be done in one pass through the flanging attachment on the lockformer?

[@sheetmetalwork]

Great question! And you are right, you cannot turn 100% of the Cheek flange. You can only turn approximately 2/3 and then you must pull the cheek out from the flanger before getting caught in the Crotch. The flange will then be completed quickly using pliers or some sort of 3/16 jig. Again, great observation B, When I find time I will try to do a demo.

[@maskdwn4445]

Confusing but I’m still trying to get the hang of it. It’s really great work but sense I’m new to this it’s a bit confusing

[@sheetmetalwork]

If there’s a will there’s a way, and if you get stuck? You are more than welcome to ask me a question and I will do what I can to help out. 😀🇨🇦

@@sheetmetalwork you’re the man brother. I really appreciate your reply and the willingness for another man.

[@michaeljowers4641]

Why do you Multiply the throat length by 1.57?

[@michaeljowers4641]

1.57 I mean?

[@michaeljowers4641]

Is that account for Pittsburg seams?

[@sheetmetalwork]

I multiplied the throat Radius x 1.57

[@michaeljowers4641]

But why 1.57 Specifically? I tried doing that and they came out short. Also I noticed that the finished Metal fitting at the beginning didn’t have any Transverse connections. I’m guess that would be for a Duct Mate application. But in and S and drive application where does the kink lines go? To the Point of the fitting or the end of the of your male 1/4” flange?
