I just took cat food or tuna cans (the steel tuna cans hold up better than the aluminum cat food cans for a repeat use) and drove 2 nail holes into the bottom. Then I would put a shoe lace or twine through the hole, and tie it to the bottom of the trap in the right spot. Wire works as well. Then, I would place the small amount of tuna, salmon, or cut up Snickers into the small can. The hardest part was setting those traps. We would put the trap between a couple of bales of straw to hold it, and sometimes we would put an old tarp over the trap except for the opening. The tarp became shredded after awhile. We caught 10 in about 2 weeks. Sorry I don’t have pictures.
