Step 4: Cortar el borte (remove de edge)


El borde circular que rodea la parte externa de la bocina tiene dos inconvenientes: por un lado, al tener un doblez hacia adentro, el sonido se ve afectado negativamente. Por otro lado, el diámetro es demasiado grande sin necesidad. Así que marqué con fibra indeleble una línea a unos dos centímetros del borde externo, y con la tijera de cortar lata lo retiré. Al llegar a los surcos de las aletas, tuve que cortarlos con la sierra porque la tijera no tenía suficiente fuerza para cortarlos.

Usé la piedra de banco para emparejar los cortes, y un cutter para retirar las rebabas.


The circular border around the outside end of the horn has two drawbacks: first, having an inward bend, the sound is affected negatively. On the other hand, the diameter is too large unnecessarily. So I marked with indelible fiber line about two inches from the outer edge and cut with scissors can remove it. When I reach the remains of fins, I had to cut them with saw because scissors was not strong enough to cut.

I used the stone bench to tidying up the cuts, and a cutter to remove burrs.
