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 ( - and + ), 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 srew), 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.

Make a bow drill:
Get a block of wood big enough to hold in your hand. Scrape out small hole in the wood. The non-pointy end of the drill bit goes in that hole. This is called the "hand hold".
You're going to use this wood block to push the drill bit against the door.
Make a bow with some strong wood and strong string. Wrap the string around the drill bit, perhaps a couple times to get a good grip on the bit.
Drill into the wood by pushing on the handhold and moving the bow.
