Corbin Calculator

This Corbin Russwin Calculator is for System 70 I.C. Cores. Simply input your master key on the top line, press the control button on the second line and fill in the rest of your control cut (cuts 2-5) and then your desired change key on the third line. Now all that is left to do is press the Go button and pin up your I.C. Core. We have also included a 7 pin calculator on this app as well. Remember that Corbin Russwin only uses cuts 1 thru 6 for pinning of system 70, so they allow a 1 master pin along with a 0 buildup pin. Yes there is a 0 size buildup pin!
