Sorry Shannel I have to disagree with you.  I made a JYH and I used a shock for 
the spring.  40 lb ram with 10 lb heads.  Works fine, and hits hard.  You can 
see a picture of it at http://www.irontreeworks.com/the_shop.htm

The trick to the hitting is that you have to make sure that the shock was 
hitting when the wheel connection was at the horizontal and spinning down. (see 
the URL)  Basically has to it hit when the shock is moving at it's fastest.  I 
got my design from the NC-JYH on Anvilfire with lots of advice from the local 
GoM friends and advice from Jock Dempsey.

Isn't sanity really just a one trick pony, anyway? I mean, all you get is one 
trick, rational thinking! But when you're good and crazy�ooh hoo hoo hoo�the 
sky's the limit!
