The interrupted thread system is good however it is normally done with an Acme or Trapezoidal thread form, which means that you must be able to get hold of an action which either already has that thread form cut in it or no thread at all and a hole bored in the breach and of the action no bigger than the threading diameter for one of these thread forms, then you can cut the thread yourself. Cutting the slots is not difficult as you just use a rotary table, however if the action is like a Mauser or Winchester (In other words not a cylinder all the way) you may have to make a special fixture to hold the action.
