| Concerning new times and hard surfaces In the last weeks have arrived to me complains concerning the use of hard surfaces under electric jackets to avoid hits being registered with machines employing new debouncing times.
I remember that in the tests we discovered that this unwanted efect was caused by deficient isolation of the upper part of the foil blade. When hitting a hard surface the foil bends much more than when a soft surface is hitted, since the circuit break time is longer there is time enough to close again the circuit via the electric jacket through the barrel if the tape is too much deteriorated. The problem is gone simply by replacing the tape with a new one or by aplying a good insolator (i.e. nail lack) to the upper part of the barrel.
Hope to have been of help
Best regards
Fernando
