In continuation of the post: «Equipment for survival: Samolovnye device Yo-Yo and Speedhook».
I pointed out there about the opportunity to comment like Yo-Yo construction of roulette …
Take roulette, in this case 3 m/16 mm.
Device think they know everything: plastic housing, spring (attached to one of the halves, plastic drum-rail for steel measuring tape, various stops and compensators.
The first thing we do more reliable fastening system. Unscrew the screw in place that will provide us the correct position of the device. Hole in the hull through and roulette do put a metal bracket.
Fix us in the right place ribbon. I stopped at 2 meters (ie, within 1 meter left). I think that it is better to fix the measuring tape, and not directly to the spring. On the tape easier to hook, a few turns in the drum belt will better wrap the cord … and if necessary, it is still a line.
Cut and drill as in the picture. Hook with a small negative angle, but in fact it depends on the wishes of the force response and hull form of roulette. Smooths the corners to when triggered more projection would not cling. Holes for fastening the cord on a considerable distance to avoid a blow hole on the cord lentoukladki. In the opening lentoukladki standing plastic compensator, I threw it away and smoothed the edges of the hole a little.
Fasten the cord without knots and twists.
To bring into the working position pulling the cord until the body of the roulette toe and move it slightly to the side until it locks.
Actuation force is very small. Because of the properties of the tape, it automatically centered by twisting.
At the free end of the cord must stand stopper to its fully dragged into the case.
In the original device about 6 meters cord. I consistently wound about 1.5 meters (2 mm diameter), if you reduce the remaining tape to 30-40 cm, will wind up to 2-2.5 meters. Probably better themselves show 5-meter tape measure with a narrow rectangular case.
The time spent on manufacturing 32 minutes. Of course the system still need to check the «field».
Happy holidays and a successful hunt.
