I was looking for some tools on the classifieds here and came across these home made machines for making chain link fence. One makes fence with 4cm (1.75") openings, the other 5cm (2"). If you're really pressed for cash, and really need chain link fencing for something making one of these machines could, I guess be useful, assuming you can buy galvanized wire for less than pre-made fence.
I suspect that at some point under communism here, chainlink fencing was hard to come by, but wire was plentiful. I don't know how it is with the younger generation here, but the older generation, at least in the countryside, seemed pretty resourceful. One of my cousin-in-laws is a woodworker-- half of his power tools he made himself.
