Both incorrect, and do either of you ever attempt such a concept on a framing square - or have either of you ever done this? Ever test your framing square on the jobsite than make it square? That's the test of a skilled traidsmen beyond say owning stairway stops for it. The ability to take a framing square, check it for square, adjust as needed than continue functioning as opposed to tossing it asside and sending a runner to the store for one that will hopefully because it's off the shelf true and square.
No offense hopefully to either, most at best no doubt had your opionion but didn't have the guts to post. Others without an idea didn't post in being silent majority but hoping to learn without any incentive by them to go further in this post or at least say something...
Anyone ever heard of an "end for end" test that both works with a
level in seeing if it's the same no matter which side is left or right, and given a pencil for a square, reversing it and drawing a
line on plywood from each side?
345 method works for a wall but doesn't allow for tollerances that 3"+4"=5" has to do with a 18"x24" framing square. We are what measuring for accuracy within the first 1/3 of the square and trusting that that's sufficient based upon some measurement that works best over a few feet of measurement verses within a few inches of noting a difference?
Incredibly important to ensure your framing square is really square, that as with your
level in a way we had to be yearly tested on in the military for our gunner's levels, and certification that we could ensure they were calabrated correctly.
Anyway for the framing square, one should do more research into what side of the corner of the
level to hit as it kind of kinks it into one direction or another in getting it back to square. Got this bronze colored framing square I have had for 20 years now. It's a part of me and square. Would rather correct than
throw it out and it's cost into the trash as if a store bought one is as a given also square.
How to correct for and adjust such a
level? How to know if it's not quite square... that's a carpenter trick that should be known and easy to test than adjust for.
