Do AE Allen decoys get brittle with age? 3 of mine have broken this year. I have never had one break before. Thoughts?
David,
Any urethane foam, if not properly painted, can get brittle with age if exposed for long periods of time to UV rays...sunlight. I have a bunch of painted birds that have been sitting on my lake house porch (enclosed porch, surrounded by windows) and they have not suffered.
Bill breakage can be an issue at times. Broken some myself, mostly when abused. Lots of guys have repaired with bondo or epoxy though neither are great ideas since they must have some "adhesive thickness" to achieve cure and bonding. That thickness is undesirable but a thin layer doesn't cure properly or hold as well as needed. What is needed is an adhesive designed to bond strongly in a thin layer. The answer is "C/A" (short for alpha cyanoacrylate)...short for superglue. The C/A that you want to use is from a model airplane hobby shop. Use the medium thick (gap filling) C/A by known manufacturers: Jet, Zap, Hot Stuff, Mercury, Bob Smith/etc.
When the bill breaks, save the end of the bill. Bond this back on with C/A, wiping the excess off while you hold it in place. While holding, spritz with some "kicker" (aka: accelerator) to speed up curing. Once it's cured, drill a 3/16" hole up through the underside of the bill, through the bill and into the head. Put some C/A into this hole and twist a piece of 3/16" oak dowel all the way into the hole and then spritz with kicker. When cured, trim off dowel and touch up the bill.
If you've lost the end of the bill, you can C/A a dowel into the head and then use Baking Soda (Arm & Hammer) and super thin C/A to reconstruct the bill. Be careful...the baking soda will "kick off", generate heat and harden. Example: you can drill a hole, fill with baking soda, drip in thin C/A...it'll smoke, kick off and harden. You can thin drill and tap it and it will hold threads. Great stuff.
If repairing a tail, use gap filling C/A and glue the tail back on...use kicker to cure. Follow that (like Steve S. does) with 3 hardwood dowels and C/A then into place.
Caution: C/A will instantly bond skin...that's what it was designed to do. It was designed for battlefield, stitch-less surgery that would hold until the victim could be moved out to a MASH unit for permanent surgery.
On bill breakage, we're still struggling with the bills of Mergansers. We're working on different reinforcing materials for strength...ongoing "research".
Holler with any questions.
