Its cool to invent, create your own homemade things, but the Time, Effort, and Tools needed...., I personally Would just get an Inexpensive Wire bending loop Tool. But agree.... There is personal Satisfaction Making it yourself.
Very cool ideas but please if you try this use a vice or brace it on a table at least to protect your fingers when using a saw like this . I’d hate for someone to follow these instructions and have that saw skip over into their fingers .
It's a good idea, but... the 'know how' is very dangerous! É uma ótima ideia, porém a forma como fez o corte não é nada recomendável, é muito inseguro.
