My house was built in 1922 and has plaster walls. I have hung a few things here and there and all is well so far. Got a 42" flat screen for the kids room and it really should mount on the wall for security and safety sake. I have had hell finding studs behind the plaster / lath walls. The way i remember lath and plaster is studs with horizontal runners then plaster over that. Would toggle bolts do the trick? Like 6 of em. I would feel better if i could find the studs though. Were 16" centers a common practice back then? Any suggestions for finding the studs besides drilling every 3 inches? Thanks!
