Wishing you luck because you said to.Today I finally pulled down the wall in my living room that bisects my home. 15 foot span, use to be an exterior wall so it has a roof resting on it that just so happens to be roofed in with the new roof they built at some point in the last 60 years as an addition. Added some columns down in the crawlspace to beef up the existing ones which just so happened to be located exactly where I needed them. Then I built a temporary wall and got to cutting studs out.
Inserted 2 9.5x1.75 LVL sitting on one foot posts in the wall cavity. Let it down off the jacks and kissed my ass goodbye. Well I am still here to tell the tale so for the time being everything has gone according to plan which is exciting. I have never taken on any structural projects before seeing as that stuff scares the bajeebus out of me seeing as I will be the first to admit that I do not know what I am doing. Well... It turns out that I do.
For safety sake and my sanity, I have measured the distance of the bottom plate of the beam and the sill plate that is still in the floor at the center of the room and will continue to monitor it over the coming days to make sure that the beam is not sagging. I do not think that it will seeing as I did not see a lot of movement in the whole thing as I was going along. Wish me luck.
...if no one ever hears from me again, we know what happened.
Get into some electronics and figure out how to install some vibration and stress monitoring alarms. One that smacks you upside the head, even when it gets false alarms.
