your 3 and 4 are backwards on your triangle(4 should correspond with the longer of the 2 short legs)...and the first time you said "if this number is much smaller than this" (on the long wall) the long wall should have been brought in at the right handside, not out on the left like you showed. that would just make the "left hand number" even larger. good video though man i did learn some stuff
nice, thanks. I work on cars but want to work on my house. I remember the pythagorean therom lol that's awesome, I know how to square it up dwn there and where to start. good deal
I get how to attach to floor joist when the wall goes across the joists. I can't find anywhere how to attach the wall when to wall runs in the same direction as the floor joists.
The air-space behind the framing and foundation wall is important so the insulation that is put in wall cavity does not touch the foundation wall lessening the chance of moisture build-up on back of insulation+++Bob
do i need to put vapor barrier on my basement walls?. i just removed the walls in my basement because they were framed with 2x2s and there was hardly any insulation behind them and no vapor barrier. i want to re-do my basement the correct way. 2x4s, r-12 insulation and vapour barrier if needed.
When framing my basement how can i check if there is a humidity problem, and if that problem exists how do i get rid of it? In my basement the washing machine just has a pipe that runs on the floor to a drainage hole so its not directly connect to the main plumbing pipe. I can actually see the water draining out. Is this goin to cause me problems??
something you have missed is that the triangle corners must all be horizontal for this to work. Otherwise you will have an error which grows across the room in just the same way as a framing error.
@podgytube I see your point,however generally, the surface of the concrete closest to the foundation wall is usually the most horizontal/level area of basement due to the slab sitting on the level footer. That being said in more extreme cases this too need be a consideration. Even garage floors have at least two decent corners to work from, Thanks for pointing out my ommision,Alot of people read these posts and this will help get the word out+++Bob
My pleasure to be of assistance. It is just that in a lot of older rural British buildings the concept of level and square is pretty loose. The concept of foundations can be pretty loose too though mostly they seem to stay standing.
Hi, Bob, great advise, I used the 3 4 5 - 6 8 10 all the time, and your right about how important it is, you look out for the next guy(cabinet guys and tile guys) and they do apreciate it, my builder swore the trim guys give him better bids when I frame for that reason alone, especially when they make shelves for closets cause thats where it shows whether your frame is square or not,
Thank you so much for this handy advice. I have a large basement and was very concerned about making the walls straight. This is so helpful. Thanks for posting, keep it up!
I have a question. I am putting up walls in my garage and I measured from floor to celing 8 ft. 5 inches. Can you tell me how long my studs should be? Im using 2*4s for the sole and top plate.
Obviously 8FT 2 IN however garage floors are not generally poured level so you may have to put bottom and top plate up first and custom measure studs to fit floor slope+++Bob
Ive worked in construction 10+ years and still see fools using framing sqaures and wondering why the projects of of square square=square over distance, so listen to bob use the biggest multiple of 3,4,5 just ramp up the units in the same ratio eg 12,16,20 (thats a ratio of 4) for huge projects just go for the biggest ratio making a 3,4,5 triangle helps too, use it to set door frames or windows then less time is spent fiquing out strange miters!
Good work Bob. Same-same... I start with one line and a corner point (squarest straight wall). Mark out 3 from the corner along the line, 4 in the 90 direction and swing an arc where it should be. Go to the 3 and swing an arc to the 4 @ 5, where they cross is my other line at 90. Snap the chalk line down. Its great how quick you present the info and easy it is to understand. Its good that trades can get the information out there to help others. Sharing information is the path to immortality!
Considering this is just a simpleton's method for applying the Pythagorean Theorum: a² + b² = c² , c being the hypotenuse. It is best to invest in a calculator, measure the FULL length of each wall, which are "a" and "b", punch in the numbers and get the exact "c" , as the "3-4-5 method" is not much better than using a framing square.
Even though I am sure your superior math skills may come in handy under certain situations in this case may just be a bit overkill and time wasteful. K.I.S.S Is usually the better way to go. Thanks for the post! +++Bob
For precision and accuracy, I agree. It doesn't take much more time than the 3-4-5 method either, maybe 7 or so calculator button presses.
a² + b² = c² - the one concept from algebra class that I remember and actually use at work. Funny thing is my laser measure tool now does all the calculations for me anyway.
I understand your dilemma.When working in any basement but particularly an old one you really have to take your time to make sure your lay-out is the best fit.This means taking existing conditions that may not totally be accurate and make a judgment call as to what will be good.The main point I am trying to make is take the existing conditions make a good decision once you do, stick with that decision throe balance of project.If you do a separate layout for each room you will have a mess===Bob
Thanks DYI.

Do you have to take the wall up to the joist of the top floor? I was trying to keep the room separate from the house for sound proofing reasons...
