How to make a tying trap

"Kukuri traps" are used to capture wild animals such as wild boars and deer. This year's hunting season is approaching, and I'm sure many of you are thinking, "I want to try my hand at making my own this season!" In this article, I will try to explain how to create a tying trap.

Things to prepare

Introduces the necessary tools and tools for assembling a kukuri trap. This time, we will explain the "flip-up type" that uses a push spring, which is the most popular type of tying trap.

① Necessary tools, etc.

1: Cutter for cutting wire rope

Prepare a special cutter to cut the wire rope. Be sure to prepare one that matches the diameter of the wire to be cut.

If you try to forcibly cut the wire rope with pliers that are not suitable for cutting the wire rope, the blade may be damaged, the strands of the wire rope may become mangled, or you may not be able to cut it properly, so be sure to use a wire rope cutting tool. .

2: Swager for crimping the sleeve (clamp)

When making a tying trap, there will be places where you need to process the stump of the wire rope or make a loop. In such cases, it is necessary to caulk the wire rope using a sleeve (clamp).

Again, use the one that is adapted to the wire diameter to be crimped. There is also a type in which the cutter and swager are integrated, which is convenient ( see the sales page here ).

3: Drill

It is a drill for processing PVC pipes for storing compressed springs. It is used for work such as opening a hole in the PVC cap for passing the wire. A handy type electric drill is fine, but a desktop drilling machine is the best, as there is a risk of injury due to shaking.

*Although there is a stand for attaching a handy type, tabletop drilling machines are not that expensive, so we recommend using a tabletop drilling machine for those on a budget.

4: pliers

It is convenient to have pliers for pulling when processing the wire.

5: Gloves

If you handle wires with bare hands, your hands may get black and dirty, or you may find yourself covered in blood when the wires stick into your hands. Protect your hands with gloves when handling wires.

The cloth type is difficult to work with, so we recommend using a polyurethane-coated nylon material.

6: Saw

Used for cutting PVC pipes, etc. Considering workability, a tabletop circular saw is the best. The price is a little on the high side, but a cheap one for woodworking is enough.


②Prepare the parts for the tying trap

Kukuri Trap consists of the following parts. The necessary materials will change depending on your preference, but if you have the following, you can create it without problems.

In addition, there are various rules when catching wild boars and deer, and there are some points that must be taken into consideration when making a tying trap.

▶ Wire ropes with a diameter smaller than 4 mm cannot be used. Be sure to use one with a diameter of 4 mm or more.

▶ Twisting (Sarkan) is a part to reduce twisting of the wire rope, but the use of tying traps without this is prohibited.

▶ A stopper (anti-tightening fitting) must be attached to the loop (snare) that binds the leg of the animal to prevent excessive tightening of the leg.

▶ The diameter of the tying trap may be restricted depending on the region. If the diameter (the diameter of the part where the snare is attached to the footboard, or the smaller diameter in the case of an oval shape) exceeds 12 cm, use is prohibited in some areas.

In advance, let's check with the local government etc. about restrictions in the area where you will capture.

How to make a tying trap

Now, I will explain how to make the spring part from here. We will explain using the wire diameter of 4 mm and the spring diameter of 12.4 mm sold at our store.

1: Cut the wire


Cut the wire rope to the required length. With the untwisted as the starting point, prepare a total of 2 wire ropes: 1 wire rope for the strut side and 1 wire rope for the snare side.

The length of wire you need depends on how big you want your snare to be. If it is too short, it will be difficult to attach the wire to the rail of the tread when setting it, and if it is too long, the range of motion of the captured animal will be widened and the wire will be more likely to twist.

If it's less than 2 meters, I don't think it would be a problem. Be careful not to mess up the edges, as this will make the next step more troublesome. If you can't unravel it, you can wrap the cut part with cellophane tape and cut it with a wire cutter to get a clean cut.

2: Prepare the PVC pipe

Drill a hole for the wire through the cap.

If you have a 4mm diameter wire rope, drilling a 6mm diameter hole should be fine. Also, cut the PVC pipe beforehand.

If you match the spring diameter of 12.4mm, the 13mm diameter of the VP tube is just right. Adjust the length of PVC to be cut according to the compression length of the spring to be used.

pvc cutting

Prepare a combination of cut PVC and a cap with a hole, a joint with a joint, and a single cap with a hole.

3: Make the wire on the support side

Create a section to wrap the wire around the strut. Pass the wire rope through the sleeve once, pass it through the shackle to form a loop, and then pass the wire rope through the sleeve again.

Then use a swager to crimp the sleeve. Do not crimp halfway, but crimp firmly. Swagers have different caulking grooves depending on the wire diameter to which they fit. Be careful not to use grooves with different diameters.

Also, if the wire rope has a coating such as tape, remove it before caulking. If you crimp it from above the insulation, it may come off completely from the crimped part.

4: Make the snare part

Make a loop (snare) that binds the animal's legs. First crimp the stump with a sleeve. At this time, make the ring of A as small as possible so that extra resistance does not occur during operation.

After that, pass the wire through the tying fitting and the overtightening prevention fitting (stopper), make a loop, and pass the wire through the tying fitting again (see the photo below).

Tip of tying trap

In addition, there are people who do not use tying metal fittings. In that case, add a little extra space to the A ring and insert a flat washer instead of the tying bracket.

5: Prepare PVC pipes, springs, and stoppers

Pass the combination of PVC prepared in step 2 and the cap with a hole through the wire in step 4. Then pass the wire through the spring. Keeping the spring as straight as possible will prevent the wire from getting caught on the way.

After that, pass the wire through the fitting + PVC pipe and connect the cap and PVC pipe through the cap with a hole.

In addition, pass the stopper that secures the compressed spring. The stopper used here should be a type that can be firmly fixed.

6: Wear Sarkhan

Connect the wire on the strut side and the wire on the snare side with a twist (sarkan). Make sure to use a Sarkan that matches the wire diameter.

7: Final check

Completion of tying trap spring

Check if there are any problems with the crimped part of the sleeve, if there are any missing parts, etc. If there are no problems, the spring part is complete.

8: For those who want to make their own treads

For those who are good at wood plywood and metal processing, it may be a good idea to try making your own treads, although the level of difficulty will rise considerably.

Tread configuration

Prepare (1) a pedestal, (2) a rail to attach the snare to, (3) a plate that the beast steps on, and metal fittings to connect (2) and (3). Let's adjust the size of each part according to the regulation of the trap diameter of each region.

If there is a groove for hooking the wire on ②, it will be easier to set. Also, use a washer at the base of the rail to reduce resistance as much as possible. Be careful not to overtighten the metal fittings so that the movement of the rail is not affected.

In addition, it may be quicker to purchase a commercially available one because the step board is difficult to manufacture even in terms of equipment.
