Another Newbie's Question Of The Day

Hello all
After broken my piggy bank for a lathe and a mill (actually sailing on a
boat to reunion island) I have no more money for the magnificent coolant
tank and pump and I ask an another newbie question :
Can I do all metalworking without this item and how can I proceed?
Can I use manually some drops of special mix with water or entire oil?
What sort of oil?
