Avion Questions
OK, it's been awhile. With lousy weather and busy schedule haven't had much time to do much work. Howver, I am tearing out the bathroom floor and have been a little surprised at what I am finding. There is a layer of OSB then 3/4" of styrofoam then two layers of plywood. There are steel "stringers" but they are separated by about 36" in the largest span. The styrofoam appears to be part of the subfloor, and not there just for insulation! :question: Also, a large section of the floor was actually being supported by the holding tank (waste)! :dead: Several screws were actually screwed into the hodling tank! :dead: :dead:
I am adding floor supports using 3 x 1-3/8" steel channel bridging the original steel stringers. It ain't going to look pretty, but it will be much more stucturally sound than what is there now. I am stopping short of doing the entire floor, since I don't want this to turn into a Major project. I am just taking out the patch that was first put in. I don't want to tackle the floor by the tub, it actually seems OK, and I don't know exactly how it is supported.
It is taking much longer than I want it to, tough to work at remote site. Seems like I spend half of my time unloading and loading my tools (including generator) in addition to the one hour drive each way.
