Lately, our Fletcher Framemaster has been acting weird. We use the single framers points in it, and the tension has become unpredictable. Some points go in the usual amount, but other shoot in almost all the way. Like, with less than 1/4" of the point sticking out. The other day, one shot clear through to the other side. If they were all one way or the other, we could adjust the tension knob, but we never know which it will be. We've had springs break before, and that's not what it is. Sound familiar to anyone?
