Drilling into walls and not electrecuting myself Answered

So these walls have a sheet of wood on them, as in, original wall --> then sheet of wood, painted. Can a stud finder still work with this wall setup? I dont want to start drilling and end up electrecuting myself and or ripping the walls up with too much weight. I plan on doing the hungarian shelfs.


Use a cheap simple compass with a load on the power outlet to trace the wiring. The compass will react to the magnetic field generated by the current passing through the wire.

Well, "react" is a very fickle term... You're power outlet is running at 60Hz, which means that the current will switch directions 120 times a second. What will happen to the compass is that it will "react" by vibrating at 60Hz. Now, if you can see that tiny vibration, that's really something, I'll give you that one.

The difference between floating and vibrating in place is significant enough that anyone could tell the difference. The reaction is actually quite sufficient.

I haven't tried it. You might be right. Still not convinced 60Hz is low enough to do anything substantial. I'll dig up my old compass and give it a go. But I'm sure you could rig up a stud finder pretty easy. You'd just have to rig up an RLC oscillating circuit that runs at 60hz. right?

the compass has to heald at a 180 angle to the wall(to float), not flat on the wall (the magnet won't float properly) and it will react to any magnet material in the area.Maybe something in your pocket or coat. In my experiance, giving it a dirty look might make it spin.

A stud finder will locate the studs by finding the nails the wood paneling and/or wallboard are held up with.

I just didnt know if it would work because of the wood paneling on top of the wall, Ill give the stud finder a try

you are looking for the stud wall right? If you want to do it for free, get a smooth finishing nail ,hammer that in every inch till you hit a stud and the next one should be 12 or 16 inchs away from that one.Don't nail it all the way in, just to the depth of two by four then pull it straigh out with in a twisting motion with vice grips.If the wood is thick I guess you have to drill.NOT FREE The electric stud finder i have uses high frequency sound waves and has a normal and extra deep switch.It also detects AC lines in the wall.One might work for you
