Take a piece of stainles steel wire with a diameter of 0.8 to 1 mm thick and a lenght of 10 cm. Take this piece of wire in a pair of roundnosed pliers, at aproximately 1cm to 1,5 cm from the end. Take the wire in your left hand, so that the long end goes trough your hand. Turn the pliers away from you and while you hold the wire firmly, turn the wire untill the pliers bounce. Now use your left thumb as a counterweight and push a little harder in order to get a nice indentation in the semi-circular shape. Then you turn the wire 180° round the axis and repeat this.

After some practice you get a nice round eye.

When you have bent a nice eye, put the eye in a vice and let the small piece of wire point up. With the help of a pair of combination-pliers you can wrap the small piece of wire around the long one. Sometimes it can be necessary to finish the wrapping with the combination-pliers. To do so, put the pliers on the wrapping and turn, while you squeeze firmly, in the direction of the wrapping. If you wish, you can file of any points that stick out. The wrapping should at least have two wrappings next to eachother.





Then you take the long part in a pair of roundnosedpliers and bend it all around. The position of the eye opposed to the other eye should be in one line.









Bend the end of the wire across the shaft of the lock.








Now you have a nice long piece of wire sticking out. Take a pair of combination-pliers and put the end in the pliers over a length of 3 to 4 mm and turn it over in a single bend. The existing hook is again taken with a combination-pliers and then turned towards the axis of the lock.







The snap-lock is finished.
