Saya ada buat benda yang sama..seelok eloknya gunakan spring yang kita pakai untuk tidurkan baby...banyak kat kedai...jika hendak hasil yang mantap pastikan paip itu panjang sedikit,sya tengok u punya,masih longgar...perlu ketatkan dia punya lock....
It is a diffent way of that trap. It's not bad, but you have to set the spring nearest to the knot, in order to block the prey's leg. You fixed the spring leaving too much space to the wire, as we can se at the end of the clip. Knowing the strenght of a wild animal is better to use a metal tube instead of plastic tube, and fix very strongly to the spring.
From the writing, I am guessing you are in Malaysia or Indonesia, but I can hear the sound of a river bird, brown in color, that is also native to Africa. This trap is very cleverly made, by the way, and I must try to copy this idea. Thanks for posting.
