Hey guys, I live in a four-plex house built in 1931, in Houston, TX. I'm trying to hang an LCD TV (about 72 lbs with TV and bracket combined), and I'm having serious trouble determining where the wall studs are.
Can anybody give me some insight on what type of walls I might have? The walls sound very solid, and the tapping technique doesn't seem to work to locate studs. The wall I want to use is an exterior wall.
My stud finder, which works perfectly in other, new houses, goes haywire on my walls. It doesn't detect any density changes in 16" or 24" intervals, and fails completely in corners and near window frames. I can't detect anything uninterrupted from floor to ceiling (so I'm not sure what's a stud and what's not).
Driving screws into any wall (from previous experience) can be very difficult, and drilling produces wood shavings in all cases I can remember. There was a hole in the drywall which I patched, and I remember that inside there seemed to be a series of horizontal boards, maybe 2x4s or so.
I've been looking for information on the construction in this neighborhood, and haven't turned up much. If anybody can give me some advice, I'd be very grateful. I'm going to buy a more powerful stud finder tomorrow and give it another try... Maybe it can find something deeper in the wall.
