 Re: Best method to find joists ?
I use a rare earth magnet, you can get them on Ebay. It is only the size of a 2 pound coin but very very strong. Use it to find the nails or screws in one joist and push in a board pin then the next joist and then you can work out the spacing of the joists.
You can also drop it in a paper or plastic coffee cup that has been left on a metal surface and laugh your arse of when your mate trys to pick it up. |
