During a travel in Laos, I need to drill some holes into a double-door's wood to install a locker. The wood is rather hard, and I don't have an electric drill (and can't find it).
I only have 2 small screwdrivers (
+ ), a small hammer, but I can find screws, nails, and other basic tools. The wood is hard (so much that I can't even make enter a small screw), screwdrivers are not good quality ones and screws are even worst.
Any recommendation for locking a door from the inside would be interesting if it's not possible.
