I'm on a snipe hunt for a special compression spring. it needs to be
conical with the large end OD around 0.390" or a bit smaller (like
3/8) and a small end OD of 1/4" or a bit smaller. When the spring is
compressed to 0.225" high it needs to push 8 - 10 lbs. force. Similar
straight compression springs have 6 coils of 0.028" music wire and
constant of 25 lb./in.

I've been trying on line catalogs with no joy, so far. Anybody suggest
a good source to try?
