I had hoped that by now I would have been able to shoot the Twister, but nooooo! The new hammer needs "adjusting" it seems. Before hacking on this one I am going to repair the one I "destroyed" so diligently , at least enough to get it to cock. With the spring on the correct shelf, the hammer still will still not rotate enough to go to full cock, the spring hits the top of the slot in the frame. So, back to the drawing board. More to follow.
