There are tools for everything! I don't know why I didn't think of this. I'll be adding this to my tool kit!
Thanks for the offer! My lineman's pliers finally allowed me to make crimp in my old elbow (not the best job, I in fact used a small hammer once it was seated to reduce the gapes I caused.) I'm pleased to say that even with the crazy, winds from yesterday and today that my stack, and guy wires have all held. The in hindsight amusing part, is when I purchased my other new duravent last year, I had purchased a straight connector smooth ended to match their pipe and crimped for connecting to source. Completely forgot that, and it wasn't with the other new items. Found it in the box with a rain cap I had bought, but didn't pull out when I was setting up. Since my guy wires have been under frozen snow for a week, I'm not changing out now, unless I have other stack issues. But, for next year, I'll be able to make the better go of it.
Points about tracking trees and tossing those low-producers either quantity or sugar content is quite the appropriate way. My very first year, we had 80 gals of sap (3 taps only!) didn't even get a gallon from it. A couple seasons later I finally bought a sap refractometer, which made worlds of difference. I tried tracking my trees/taps for a year or two but didn't stay disciplined to it. I really should, especially, as you know, toting sap isn't easy work.
Planning on tapping Friday or Saturday. Glad I don't have bags/buckets up for this windstorm.
