Intro: Fish Trap
Its a trap... for fish. Its pretty much the basic trap that uses the funnels where fish can swim in but not out.
Step 1: Materials and Such
most of the materials and such in this project can be subsituted and worked around depending on what you have.
-some sort of mesh
It needs to be small enough that the fishies cannot swim out of it. I used a plastic mesh that i got from the fencing department in lowes
-thin enamel coated wire
They dont need to be very thick, i used bamboo kebabs.
posterboard, wrapping paper
something that you can use to make a cone stencil
something to cut the mesh with
needle nose pliers
Step 2: Cut the Peice
The trap consist of four peices , two cones , the cylinder body and the door.
to make the cylinder body just measure out a rectangle of the mesh, The rcylinder should be about twice as long as it is wide so keep tht in mind when you cut the rectangle.. This step isnt real hard its basically cut a rectangle.
Step 3: Roll and Connect
So now you need to roll the rectangle into a cylinder . Try to leave and overlap of about 2 units of the mesh. Then used the thin wire to weave the two sides together Start at the edge of the mesh and work across making a seam. Do it as if you were sewing the mesh together with the wire and every so often make a couple loops around the two edges to reinforce it. Using needl nose pliers to pull it through it makes it much easier.
Step 4: Ah Yes the Cones, the Cones
The cones are made out of a half circle of the mesh rolleds into cone shape and connected with the wire. I found that the best way to make it fit was to first make a cut out with the poster board and then adjust it to make it perfect then use that peice as a guide line for the mesh. Its best to keep a little extra on the cone peice because its much easier to trim down than it is to strech it. The angle of the cone should not be to steep Mine was about the same as a typical kitchen funnel. middle of the cone should be a little bigger than the size of fish you want to catch. dont try to catch avery big fish without a very big trap because it will not work.
Step 5: And Now for the Hard Part
The attaching of the cones to the cylinder is the hard part. The cones need to be inverted and attached with the wire to the outside edge of the cylinder. This is also the part where you need to trim off any extra on the cones to make them fit well. start at one point on the edge of the cone and cylinder and then "sew" around the cylinder.
Step 6: And Now for the Harder Part
This part requires an arc welder, plasma cutter and a large jackhammer. Or you can use wire cutters and scissors. now that you have you lovely cylinder and two inverted cones on either side its time to add the door. The door is most critical to removing the fish you caught and adding bait and weight. Decide what size you want your door to be and then cut out a piece of the cylinder that size. Next find a piece that when folded in half is about an inch bigger than the opening on all sides. Fold the piece in half to double it over and make it stronger.
To stiffen the door I used a piece of thick wire that a wound through the piece of mesh on the side of the mesh that was not closed from folding over.
Step 7: Attaching Said Door
Uses a coil of thick wire to attach the door. twist the coil of wire through the mesh on the top of the door and the top of the opening. If you look at a composition notebook that has the wire coil then you can see and example. Then uses two little loops of wire to secure the two sides of the door hinge.
