Great video. Getting into the union and one of the question was kinda similar to what you were doing..... I got it wrong. Lol, but I now know how much I need to cut off for my offset.
Honestly I’ve never had to do one, but cudos to all that have. Nowadays a few clicks on a computer and off it goes to the plasma table. Again to your point, if you are able to take an offset that is on site and turn it into a double offset, I have no doubt in my mind that you have a good understanding of the trade. 👍🇨🇦
@@sheetmetalwork it's a thing of the past to me also. I too just "go to the computer" nowadays!!!! Even if I don't plan to burn something like a single simple channel, I use the 3d modeling to get my bends if ID/OD critical. I stumbled on your channel to send a good clear owl method video to my friend because he is studying for a smw test. Your video was the most well explained.
Yeah but if you are out in the field, you don't use a computer, you just use math and your hand tools. It's called sheetmetal work, sometimes you've got to work the metal, not the mouse.
In theory, would the owl method work on say a 3 or 4 sided offset? As long as it is going to a duct size of the same dimension( 10x8 to 10x8, 12x8 to 12x8...etc)
I’ve had many inquires. Hopefully someday, I or another journeyman out there will add a comment on how to help those who want to improve their shop tickets sketching skills.
I appreciate you . Also when measuring one middle duct piece needed for install . Do you measure from drive end to drive end and then add an inch or just cut the duct work to the measurements of drive end to drive end ?
@@elguapo876 it's going to be drive to drive for your connection, if that's your question. I find the method where you go corner to corner, then come in the length you need to offset, then come up at 90° to that corner to corner line (the middle example in this video tutorial), to be the quickest and easiest.
Great point and thanks for your comment, I can see that you have experience with this type of issue. First thing I would like to add is, the best scenario would be a proper offset. But in the field we must do what needed to get the job done. In this case, a journeyman Sheet Metal worker would know that he must make the necessary adjustments and remove the miter allowance from both the installed duct and the mitred duct. The same thing as as an architectural Sheet metal worker would do on a Gutter downspout that needs to offset.
@@sheetmetalwork I have been in the sheetmetal industry for 44 years (retiring this year). Stumbled on your channel and found it very informative for sheetmetal workers. Its amazing to find all the sheetmetal layout channels on youtube. I was self taught.
@@keithsac2542 Thanks! I’ve been in the trade since 1983, time flies, I plan to retire in 5 years. Hey! I know how hard you must have worked, and 👏 Congrats, I hope you can enjoy a well deserved retirement.
@@joebaker9861 yea typically the top is for the s cleat so you need 1 inch allowance for it to slide in. On the sides you’ll have drive cleat which you’ll need the 1/2” allowance to fold over for the drive cleat
Still with Inches? when americans will get to use real units??? meter was used since ancient Egyptian times... started with a drop of water measuring always the same... 1cm... from there they developed the meter, the cubic, calculated Pi, etc...

You explain perfectly! I’m in this industry in the uk I have a set to correct tomorrow and you have just regained my confidence!! Thank you :)
Thanks for commenting, I’m happy you found the video.
This was an awesome way of explaining offset fabrication for duct. Thank you so much. Very helpful and easy to understand.
I’m really happy to hear that. Thanks

Thanks! Happy to hear we’re on the same page.
Definitely helpful glad I came across this👍
I do hope it helps 👍
Listen to all you apprentices if I taught you anything ….”do your best pookie the rest”
Excellent instruction video👍 Cheers!!!
Thank you Paul!
The owl method can also be used on ogee offsets to make on-the-job double offsets.

.... also the owl method can be used to increase or decrease the offset in an existing offset. But there are limits to that.
Sorry I'm on a roll!
It’s always a pleasure talking with someone using the same language LOL.

This is amazing
Awesome

Your welcome!
Great.
Thanks 👍🏻
Hola gracias por la enseñanza.. quiero saber si el ducto no es un cuadrado osea si fuera rectangular,, cómo se realizaría la formula del búho
👌👍
Thank you!
Would this method work if your trying to make a 45 degree piecut offset
Sorry Benji, but I’m not quite sure what a 45 deg piecut offset is? Again Sorry.
Do you have any tips on detailing and drawing duct orders
I’ve had many inquires. Hopefully someday, I or another journeyman out there will add a comment on how to help those who want to improve their shop tickets sketching skills.
Always draw your fittings as if you're looking at them from the top down. That's #1.
Can you do one with the whole installion of s lock and cuts needing to put it together :
I’ll try. Thanks

Extreme offsets will cause the size to grow and may not work.

This would’ve been a great video if you also showed how to measure for the tabs and assembly. For us beginners, that is required information.

Dear sir,upload 4 side slopes square duct reducer and formula show clearly please waiting for this one.
Hello Jahid, here is a video link for a reducer with all 4 sides sloping.

I live in 🇨🇦, we also use metric. 1” = 25.4mm etc…
