Hart spring tool

[David ilvedson]

I suggest you practice with the tool before working in a 
stressful situation.  There is nothing wrong with the Hart tool.  
It won't do the job for you.  You need to have some skill in in 
the use of it or any spring adjusting tool.  Ideally the tool 
would contact the side of the repetition lever when re-intalling 
and voila the spring would be in the groove.  It doesn't work 
that way in the real world.  Re-install the spring and give it a 
little nudge and it will go into the groove.
