confectionare dalta

Recommended Posts

Am facut asta ca lucrare de laborator când eram student. Am facut si măsurători de duritate după.

OK, cam asa se face, insa mesteru de la care am furat un pic de meserie nu se uita la culoare.

Dupa racire dadea cu pila, cind incepea sa prinda era clar ca s`a "inmuiat" materialul, din nou in apa, in rest la fel ca tine, doar ca testul il facea cu pila.

Am incercat si eu si iese bine, un fel de calire superficiala, miezul ramine tenace iar taisul dur dar nu casant.
