One of the biggest problems with framing studs today is that they are cut from the center or near the center of small trees. I don't know if it's true, but a friend of mine was telling me that the average tree cut down today is no bigger than 6 inches in diameter.
If you look close enough at your average 92 1/4 inch 2 x 4 wall framing stud, you will see some pretty tight tree growth circles on almost every one. This should give you a pretty good idea, how small the trees actually are.
If you can avoid using wall framing studs that were cut directly from the center of the tree, you're going to eliminate a lot of problems with your walls later on. These are the wall studs that usually twist and bow the most.
The next time that you see a twisted or bowed piece of lumber, check to see if it was cut from the center of the tree. The center cut lumber, as is often referred to by contractors and lumber yards, can create big problems for contractors and home builders.
Another contractor secret that I would like to share with you is that you could save yourself a lot of time after the house is framed and you want to straighten the walls, simply by building your walls with the crowns of the lumber facing the same direction.
In other words, if you were to look down the entire length of a wall framing stud and it was perfectly straight, you could simply lay this one in any direction. However, if you look down the entire length of the wall framing stud and you notice that it's bowed in one direction. You should make sure that you frame the entire wall with each stud bowed in the same direction.
This will prevent irregularities in the finished wall. If you have one wall framing stud bowing in one direction and the next one bowing in the opposite direction, you can just imagine what the finished walls are going to look like.
I don't reveal my framing and construction secrets too often, but when I do you need to pay attention. The biggest difference between an excellent contractors and your average contractors are the secrets that they hold in their head.
