Interesting. We found some 3/8" drywall in the 1913 house, dating from some renovations that appeared to have been done in the 1950s or 60s. We also found a mummified sandwich.

Modern lumber is planed, so some of that difference is because of losses from that. If you open up the walls of a house built 100+ years ago, you see these thick rough wall studs that never went through a planer. Even with shrinking, it’s close to being actual 2" x 4".

At one time a 2 x 4 really was 2" x 4". Very old houses will have these in the walls, not planed and quite rough and splintery. I think I still have splinters from the 1913 bungalow I renovated more than 30 years ago.

I bought stocks of Ballard Power years ago when hydrogen cells were going to be The Next Big Thing. Not many stocks thankfully, because it slipped further and further and then got delisted. It seems to be one of those things like airships that gets revived every 20 years or so.
