[TheForge] JYH Trip Hammer question

I am going to start to put together my JYH power hammer (a copy of the NC JYH 
from the anvil fire site) and I have a question (Jock..if you are listening, I 
think you are the one to answer this but I will take advice from anyone).  
Jock told me to use a leaf spring for the hammer mechanism. Now here are the 
questions

1. What diameter is the rod connecting the wheel to the mechanism?
2. Should I reinforce the wheel (the metal part..rim?) to take the continued 
extra shock of the above mentioned rod everytime the hammer hits the anvil?
3. I found a regular size leaf spring of an old station wagon.  I would have 
to heat and bend it and I think that this would affect the spring and I dont 
think that I could get the spring back to "springyness"....so I thought I 
should buy a small leaf spring for a dune buggy (I found them at Northern 
Tools).  Advice?
4. Surface of the anvil and the hammer....any good particular choices? tool 
steel? High carbon something of other?
5.  Will filling the upright and the anvil with sand add stability, strength, 
dampening....or am I just out of my head here?
6. Will I stop asking questions long enough for someone to answer?



Okay .....

Advice?
