Craig:

I did get a replacement spring from Lancair but no background 
information.   I used it to measure the length, I.D., O.D. and # of 
coils.  To determine the rate of the lancair spring, I need to determine 
the load on the spring when it is compressed.

Unfortunately, I cant measure the the length of the spring when its 
compressed because I cant get access to it and the installation plans 
dont show the depth of the spring mount.  Thats why I was hoping someone 
on the list might have a step that hasnt been installed.  They could 
measure the length of the spring under load, then measure the applied 
force to compress the spring to the loaded length, and then we can 
compute the rate and go from there.

BTW, Lee Spring did send me info on two springs with the same 
dimensions  as the Lancair spring. The first had a rate of 16.00 lb/in 
and the second had a rate of 17.50 lb/in.  If I could determine the rate 
of the Lancair spring, I might be able to pick the stronger spring (maybe).

Appreciate the interest.  Regards, Bill Hogarty
