DELINEADOR DE 2 RUEDAS
Hello: This version works the same as the previous one, the pencil slides in the channel until it makes contact with the paper and the line is drawn. The construction is simpler, just a piece of sheet metal with two bends to form the support channel of the tracing element (any shape and size); two turned wheels fixed by pressure bolts or rivets and two non-slip rubber bands (commercial).
