Thanks, some of the other instructional videos are missing the phantom run. I agree, it should be included because otherwise, using only 40" run, we would actually end up with a shorter piece of wood being used than is needed.
Iggynotpop Thanks for the compliment and yes your scientific calculator can get the results. For carpenters the Const Master is basically a scientific calculator but gives results in “carpentry speak” quickly and efficiently so it’s our choice of took to train our students
Thank you so much for the video series. It's a huge help. If I may ask a question, would it be more accurate to just use the Pythagorean for the unit to get the pitch length vs the length of stringer / #risers. Like say 7 1/4² + 10² = pitch length² ? I ask because I am trying to find the most efficient and accurate way for my exam and I get different measurements for each process. My gut just tells me that is the formula gives you the stringer length, why not just use the unit rise/run in the same formula to get the pitch length.
Hi, fantastic video, I learned a lot thank you. I’m a bit confused when you mentioned the calculator ROUNDS of when adding the pitch size. Also once you have that size would it not be more accurate to use a large set of dividers? Cheers
thanks for the comment. Yes a large dividers would help and we have added that to the project here in our carpentry lab. Just not the video. Keep the "chips" flying.
What if someone that is not a carpenter and does not have a carpenters calculator, what’s the formula to figure out the length of the riser? I know this is an old video, but very helpful and I’d appreciate any help! Thx, in advanced!
@@glenmartin629 ok thank you. So therefore in your example total rise is 37 7/8 and your rise is 7 9/16. Does that mean that the rise is 7 9/16 minus the finish floor material, meaning the rise of the stringer would be smaller then 7 0/16 correct?
Each riser, when all the finished stair material is installed will be exactly the same. Watch further videos to learn how you compensate your layout for various finished floor material. At a minimum you would reduce the first riser (from the bottom step) by the thickness of the tread IF you are using all the same finished floor material from lower floor to upper floor, (example, carpet) Hope this helps. @@victortorres3187
In the USA we are stuck with the fractional system so won’t be changing. Of course all the formulas and terms are the same so I would just enter metric numbers that would work for you. Thanks for watching and your kind comment
Yes, we are teaching the steps for a typical stair. IF you have a different run larger than 10" most carpenters may have to revert to the calculator to get the total run. Such as 10 3/8" unit run x 15 treads. Thanks for watching.
The best how to stair I have seen, amazing
Adam Trudel Thank you. Keep,it level, plumb and square 😃
Couldn't find a better example than this , bravo I salute you sir👏👏👏
Way to go Glen!!! Excellent!!!

Best video I've seen that explains this. You can also get the angles using sin cosine and tangent on your scientific calculators

I searched many video to finally find this very simple explanation. Good job
Mike T Thanks
in short FANTASTIC,THANKYOU

Well it's easy with that calculator you have. Nice little gadget .

Does the run include an inch (or more) of overlapping for each tread?
Excellent teacher
Very very good well explained video. Thank you
I'm glad you found it helpful. Thanks.

Best example of how to figure out the sizes, many thanks.
Excellent explanation. Just a note: working in metric would greatly simplify layout spacing calculations.
Agree. But like I tell my students “American carpenters are behind the metric system every Inch of the way”
I'm only a Renter. Believe in repairs. NYC
does this include the rise if you include the board on top of the stringer? Or does that not matter?
The total rise is the amount up vertical travel from lower finish floor material to the top of the upper floor finish material.

very helpful, thank you. Really think you got great quality and teaching in your videos appreciate it!

Thanks for that video,it really helpful, but i hope next time you using the metric calcution...milimetres

@@glenmartin629 thanks
bro needed a calculator to get an answer for 10 x 4 .....

@@glenmartin629 got it! thanks
Very good video but overcomplicated
