Hi Rick, your concerns are well founded!
I've had many springs mount a counter attack just at the point of success..... And, many center their attack right to the nose!....
... But, if you notice there is quite a distance on the winding center pivot, I can mount a complete cover shield and still have room to work.... I just didn't want the guard to be the cause of the accident...
.... we will see as we go... Best to you Rick, til...lat'r...GT BTW, Rich & Rick, If you need any of this spring steel strip, it is: .780" X .020" 1075 blue temper (mid 40's Rockwell C ? cuts & drills ).....let me know...
