Have you ever come home from a day at trade school and thought to yourself that it would be nice to have a bunch of videos pertaining to the math and science of your particular trade. Well Tradestutor is here to fill that need. My goal is to make videos that give you that extra help during trade school which could make all the difference on your exams.
I had a lot of excellent instructors during my time in trade school but often I wished that their lectures could have been recorded so I could watch them later. The videos I've made represent those lectures in a format that's easy to absorb in a short period of time. Each video generally lasts no more than five minutes and gets right to the point.
I hope you enjoy the videos and good luck with your courses!!!!!!

I did 42 x 0.414 is that just for 22.5?
Thank you! This is exactly what I needed to know.
When would i be using this formula when a degree of roll isn't specified? Or just when trying to get from a to b??
Thank you so much!
Gold !
Are you gonna spend 20 minutes to measure all this? There’s gotta be a faster way.
thanks
Easy formula 1)Spread of pipe center to center 2)1/2 the tangent of your degree of offset 1/2 of degrees tangent X spread of pipe center to center
I enjoyed the training, but where is the formula 0.414 derived from? Okay, I looked back at the comments and found where you answered my question. What might be good to explain here is that the center point of the elbows are at 22.5 degrees, in relationship to each-other.
Excellent explanation bro 👍, thanks
Hello, can i contsct you about 1 on 1 help
Do you still have to take off for the two 45 fittings?
Remember, the travel length is the distance from the fitting center to center. You must subtract the "A" value at each end to get the pipe length.
Love the breakdown into a melodic solo in The beginning 🤘🏻
Does this formula work for a single piece of 8” pipe?
No comment on subtracting for the amount of straight in the Els ??
I understand but what if the offs t isn't 17 does the rule still apply
That was such a difficult way to explain it….. It’s really not that difficult.
So I tie in watermain all the time.. how would I find the angle like should I use 45s or 22s
Everyone that builds anything should watch
Freaking awesome
This hurts my head 👿
Beautiful 😊
Thank you and thanks for watching.
1.414 where is this from and how would you calculate for other than 45?
Very helpful thanks!
You're welcome and thanks for watching
Thank you
You're welcome and thanks for watching
Can not rely on this information cos it's wrong ! Energy is measured in kWh not kW. Won't be watching the other videos.
This helped me understand 45 offsets in the simplest of ways. You should have added 2 more lines in there for more depth! But good information
I'm glad it helped. Thanks for watching.
Is advance the same thing a "run"? Please need your help y im confused about the terms
How do you figure out the rolling offset of a fitting? Got a 90 degree fitting, that I'm rolling on a 45 that I need the offset for.
👎🏼 you didn't explain how to account for the length of pipe used in the bend itself - where to start each 45° bend. That would be 5" for a 1/2" pipe with a 90° bend. What is it for 45° bend?
Just mock up your two pipes or get a fixed measurement of where your second pipe is going to be or where you want it to be then do exactly what he said, follow the equation. You are worrying about something that is irrelevant to the situation.
Also I get what you’re saying but just make the pipe a little longer than it needs to be man then it will be easier once you get the travel piece cut and mock up the second 45 and mark it where it needs cut
Gracias
Would this work if my pipes are différent sizes?
Y are you using 16ths
We generally go with 16th's here when dealing with the piping trades. This may differ in other parts of the country but here is just a standard we seem to go with. Take care and thanks for watching.
Can I just get this for laying out framing?
So the offset is the horizontal distance and the rise is the vertical distance?
AHHH dang This made me understand fitting allowance much better!
Awesome! Thanks for watching.
Thank you, this was simple and straightforward. I am currently in college trying to get my associates in Electrical power Lighting. At first I had trouble calculating the current flow but now I got the hang of it 👍
What a great and useful video!
I'm glad it worked for you. Thanks for watching
It is work on hdpe pipe?
Am more confused bro explain yourself
That was really helpful
Glad you liked it. Thanks for watching.
Whoa not sure what the hell you are trying to do here! This is incorrect information 100% .279” is closer to a 1/4” (.250”) than it is 3/8” (.375”). My question would be who would give you a measurement in this configuration being so specific as to go the thousandth, and then be agreeable to an 1/8” error rate?? 4.279’ is something I have never seen on a print. 4.279” maybe but never the former. I am a machinist by trade so it’s possible that this only applies to carpentry and iron workers. We definitely measure with different tapes. 1/8” (.125”) is a mile off in my trade where as carpentry and Iron workers can be out by 1/4” and still be in spec..
Ive seen this method but they based their measurements off the ¢-¢ of the pipes and not the gap. Can doing this cause issues ?
The measurement should be from center to center. That will be more accurate.
Thank you
You're welcome and thanks for watching
Thanks for your sharing
I'm glad you enjoyed it and thanks for watching.
Excellent explanation ! Thank you.
I was having trouble and now I'm.closer to understanding all this. Most videos don't EXPLAIN reasons why you do the math. THANK YOU SO MUCH. can you do more transposing for physics and trades math
You're welcome and thanks for watching.
Where do you get the the 1.08? and how do I find the right number for all angles. Like I know 45° is 1.1414
It is good to use inches or mm? or doesn't matter the unit of measurement?
