Thanks for the reply Ed.  I will take all the advice I can get
from folks like you.  Being new, I was not sure if I was 
calculating correctly when the length of the finished cap 
shrank down to below 4'.  I'd hate to roll up a cap just for the 
garbage man.
BTW, I tried to use an variable speed drill to wind the secondary.
It didn't work.  Got to chuckle about it though.  With all the antics
going on I'm sure the attempt looked pretty stupid.
