Fabricate an offset with two elbows 

Thanks Fredy,

،Thanks

Thank you Noah.

Thank you very much.

Thanks👍🏻

I think your looking at the wrong video regarding OWL, This video explains how to fabricate an offset using to elbows………..The OWL method is the allowance you must remove from both ends of a straight piece of duct to CREATE a MITRED OFFSET. But don’t forget this is simply one way to accomplish the mitred duct and that there are others ways also. If your really interested in learning how to fabricate a field mitred or so called slashed duct? Check out my video on how to fabricate a field mitred duct. The important thing here is that you must try and pick up tips and tricks from many Journeymen along the way :)

book by Joseph J. Kaberlein called Triangulation Short-Cut Layouts page 267.

Hi Jay, That’s a good question, in reality on a job site adding an extra 1 inch or 2 inches would not make much difference, but to answer your question if you look back at the video I have been working from my Finishline therefore I would only add 1 inch total if I was working from the 1 inch line or the working line, then I would be adding 2 inches.

Hello Juan, sorry for my late reply but the book is by Joseph J. Kaberlein, the title is Triangulation (Short-cut Methods)

I’m not sure what you mean by how to check elbow degree, sorry.

Yes it does, The only difference is with round elbows you will have to add an inch and a half for overlap on both elbows, therefore you would do the math and add 3 inches to the net length of the in between pipe.

Oh ok thankyou that makes sense. Your videos help out a lot as an apprentice just starting out thanks again.

Yes you definitely couldThere are many different ways to measure, as there is for most anything else we do in the trade. I believe it;s best to pick up tips and tricks from all the different co-workers and then choose the ones you prefer.

@@sheetmetalwork yea I’m starting to pick things up from other workers. I just started hvac few months ago! But I’ll be tuned on on your channel for more insight. Thanks a ton you rock!

@@-slurmdaddy-8147 Thank you!

Your right, Ive heard it pronounced that way many times also. Thanks for the comment. 👍

That's how we say it in our shop

Oh Yes it does, just make sure to add for The overlap on the Big Ends.

@@sheetmetalwork thank you

@@sheetmetalwork 1 more question I’m a helper trying to get better, how would you find an elevation to run ur duct or taps if one isn’t giving on the print

@@omozusibenji That’s a difficult one to answer. Is it residential? Commercial? What type of ceiling? Just make sure to run your ideas by your supervisor before doing a whole lot of work for nothing ☹️

@@sheetmetalwork Tenet work ,9 3” Ceiling hanging 10*10 duct, I understand when no elevation is giving you pick one or run high as you can but do you have to calculate the depth of the duct When you pick an elevation or just pick that Elevation
