In today's video you will learn how to use a framing square to build a roof. There are at least four different methods for calculating rafter lengths for a roof, and in this video we are throwing the calculator away and using only a framing square to find our rafter lengths.

@mikefinley4367 2 года назад

Awesome education many framers never use anymore due to manufactured trusses commonly used. Here's a question ... When two roof pitches intersect making a valley, if the same pitch or not. How do you get a accurate sheeting cut on the end into the valley? I swear two of us had screwed up four sheets after both measuring twice before cutting. Measured distance from end of last square sheet at top and bottom and it didn't work.

We have a roofing square in the UK made by G Gibson. Its metric but its the best and most thorough square sold. You can work out every possible bevel needed on a roof. We mainly have a degree of pitch to work with rather than a rise/run.

@ac-jn3wz 2 года назад

Is there another purpose to use a spade bit other than framing? Can it be used for fine wood working? I try to find a video how they use it on youtube but no one seemed to be using those other than framing.

@jussikolehmainen6310 Год назад

Might be a bit too rough for fine wood working but if its not visible then why not. But I find it more satisfying to use bits that make holes with better guality. Spades are more of making a hole fast and efficient and they are not too sensitive for driving into nails. Also cheaper that good guality drills.

Thanks RH. You mean the same run measurement?

@RH-vm1pm 2 года назад

@@TrainingHandsAcademy Thank you for quick reply. I was confused about the run for a common rafter vs run for a hip rafter. They are not the same length. After many of your videos and calculations I figured out that 12" (common)) rafter and 17" (hip rafter) have to be calculated as the same (one) unit? Do you/training hands academy have hands on classes? Thank you :)

@TrainingHandsAcademy 2 года назад

The overhang amount and soffit cut numbers are almost always different for every roof, and it really comes down to design, preference, and/or what type of trim you’ll be using. Therefore, the 4" in this video is just an example. Hope that helps.

What is the long hand math ( not using construction pro) to calculate the Jack Rafters? I get and understand 95% of all your rafter playlist. I can manually ( long hand ) use math to get hip and common and all the other parts. I have put all this in an Excel sheet, But what I can’t figure out is the math ( again, long hand ) of finding the jack rafters.

@TrainingHandsAcademy 2 года назад

The math is unit run over unit length = total run over x (total length of Jack). You then need to solve for x. For example a 8/12 roof would have a jack length of 19.23 (19 1/4") The math is already done for you on a framing square. Third line down on the rafter table shows "difference in length of jack's 16 inches centers" which again is 19 1/4". Therefore, the difference (19 1/4") is actually the first jack length, IF your layout is from the end of the valley rafter (or overhang), OR that 19 1/4" can be subtracted from the (common) king rafter's length to get the first jack rafter to the right or left of the king rafter. You may or may-not need to subtract the 7/16"... just depends on how you frame the valley or hip. Bottom line, the numbers are all on the framing square which is really great. I need to do a video on this. I hope that helps.

Frame roof rafters with a framing square as intended. Keep exercising your brain. Use it or lose it........

@DrThunder88 2 года назад

While this does give a good idea what the numbers mean on the square, I think your explanation gets a little lost in the weeds. Though, ultimately, you still get the correct answer! Dividing the run by 12 isn't converting it to feet, otherwise your outcome would also be in feet. Irrespective of the unit your run is measured in, you'd still need to divide it by 12 and it would still work with the values on the square! Inches, feet, meters, metres, furlongs...it doesn't matter! As long as the slope of the roof is expressed in inches of rise over 12 inches of run, the ratios of the triangle's sides will remain the same regardless of how the actual building is measured.

@TrainingHandsAcademy 2 года назад

That is fantastic. Thanks for adding this info!
