Bob,
I gather from your correspondence that you can make SS cones or have access

Ed,
What would be the dimensions of the cones if someone were to make them?

Sounds like the right formula, George - will wait for your project's

before I try cones.  Yes, I did find some cone  inserts at $60.00 USD
each.
I would need 4 for my two tubes - hummm makes one tube sound better all
the
time.
