How to Find Metal Telepost in Finished Wall

bhumeny

To fix a problem with some walls on the main floor, I am trying to locate the metal teleposts in the basement. The problem is that the walls are all finished.
I have the blueprints which should show me exactly where they are and I have been able to locate 2 of the 3 I am looking for. I have cut 3 holes in looking for it and can't find it.
Does anyone have a foolproof method of locating them without cutting any more holes? I have tried 2 different stud finders and one gives a slight reading when I tested it over one of the other telepost locations, but nothing on the wall where the telepost is supposed to be.
Any advice would be greatly appreciated.
Thanks in advance.

Try measuring the distance of the two you have found, to calculate the distance of the third.
(Spacing between eachother, or spacing from foundation frost wall, etc...)

Good idea, but it won't work in this case.
The 2 I found are side by side due to a dropped ceiling.
There are no more on this portion of this wall. It is staggered from the other bearing wall.

try a BIG magnet, Also the old school knuckle knock, you can find "solids" and then magnet it it sticks you got it.

usually the foolproof plan is to check the blueprints!

i don't suppose you are lucky enough to have drop ceiling that would allow you to poke your head into and look from above

here's a thought. could you be having the problem on the main floor due to the fact that there is no 3rd post?

Got an idea form elsewhere.....
Drill a small hole and use a metal wire or coathanger to fish with.
If there is a post, you should be able to "hear" it.
Thanks for your ideas/comments.
