Here are the steps I would take, divide 24' by 6. Lets just say you have to put 5 window's in a 24' wall centered from the outside corners.
#LEVEL 10 HOUSE FRAMER WINDOWS#
For example, 2 windows = divide by 3, 3 windows = The trick to using carpentry math to locate multiple, evenly spaced, windows is to divide the spaceīy one more number than you have windows. The first step is to determine if the windows are centered in the room or from the outsideĬorners. Often you will be required to locate two or more evenly spaced windows in a single room or The center hallway mark and lay opening out from there. I've found it easiest to find theĬenter of the hallway, then divide the header size in half. Let's say that you need to center a door in a hallway. Many times the exact location of windows and doors are not clear on the blueprint. Numbers should be entered as whole number and decimal points, for example. The Pythagorean TheoremĮnter any numbers you like in the first two boxes and press solve for the hypotenuse. Check out the neat little calculator that I found the other day, go ahead play with it all you want. This can alsoīe accomplished with a regular pocket calculator. You can also go fromĮxact point to point for a very accurate 90 degree angle.
ForĮxample, 3- 4 - 5 or 12 - 16 - 20 can also be used.
You do not have to simply stick to 6 - 8 -ġ0, you can use any division or multiplication of this number. Is nothing more than the old 6 - 8 - 10 rule which many of us use everyĭay with out realizing it. Happens to be shaped like a "L" then you need a more powerful tool called the "Pythagorean Theorem". Many times objects are shaped different than a simple rectangle. Straight forward process of measuring diagonally until you come up with When the object needing to be squared up is a rectangle it is a rather One of the every day carpentry math problemsĮncountered by carpenter's is the squaring up of walls or sill plates. Here is what it looks like on the calculator. This will give you the length of the studs. Here is the procedure I usually follow, add the two wall height's together, add the floor joist dimension, add the sub floor dimension, and subtract the wall plates thickness. One of the more common problems I have encountered over the years isĭetermining correct wall height. Measure the two numbers together Wall Height Has you stumped? Borrow your co-workers tape measure, then simply Addition and Subtractionĭo you need a quick answer to an addition or subtraction problem that
Simple pocket calculator,tape measure, and a little practice. The job can usually be accomplished with a You do not really need to know every aspect of these Such as trigonometry, geometry, hypotenuse, or Pythagorean Theorem.Īre many different ways to apply every day math to these some timesĬomplex equations. Simply because they are intimidated by words, Many carpenter's never venture beyond simpleĪddition and subtraction. In mental terms, carpentry math is the hardest part of any roughįraming carpenter's job.
