HOW TO DESIGN A STRING CUTTER?
Is there any device or design or something similar of a cutter for soft string (like gittar string but softer) that cut it in 1 cm pieces?
This one does it automatically, works with softer wire, and programmable down to 1mm lengths. Not sure if it works with solid wire though, but there's probably similar machines available that do.
If you are looking for the mechanism for cutting the wire please see below.
I have posted 3 videos showing different ways to accomplish the cutting action.
It will most likely NOT work for your 1cm lengths but could help provide ideas as to how it could be accomplished.
