More on Glue and Birdfeeders etc.
Faithful reader Harry "Gipper" Morris has raised a couple of great questions concerning glue and building birdhouses. Being a hobby boatbuilder, former cabinetmaker, and glue collector, I think I can almost address these concerns as an "expert". (Below is just a small portion of my collection... Abandon all hope...)
Harry writes about "Gorilla Glue", "Gorilla Fast Drying Glue", Elmers Waterproof Exterior Glue", and "Testors Cement for Wood Models": "So far, they do the job but I'm not satisfied with any of them. I will try to test those you've mentioned as soon as I can get to it."
CapeCodAlan replies: Judging upon a later comment (see below), I'd say take a look at something like "J-B Weld"... That's basically a non-toxic industrial epoxy that will set ("kick") in 4 - 6 hours. (Full cure time is 24 hours.) While nothing will fix a hopelessly mangled joint, a good epoxy and screws go a long way. On the other hand, something like "Uglu" might have promise. (Note: I've never used Uglu.)
The next question goes as follows: Many areas of Birdhouses can't be clamped except maybe with rubber bands. Waiting 24 hours for glue to cure is a pain. I'm an impatient builder. And what works fast, doesn't hold up very well in exposed exterior environments.
And I reply: Clamping is an art. (Hence the photo here.) Aside from springboards, there's always the Spanish Windlass (basically a rope wound around the obstinate beasts being glued, and then tightened tourniquet style), wedges, weights, ratchet strap clamps, temporary nails, duct tape, vacuum bagging (everyone overlooks this), levers, hot-melt glue (you can temporarily hot-melt pieces together while the real adhesive kicks), and of course there are the good old fashioned clamps.
I guess for me, backyard adhesives come down to four issues:
- They need to be non-toxic
- Glues should be strong and at the same time gap-filling - hence my love affair with epoxy
- They shouldn't demand extreme clamping pressure - hello epoxy
- Mechanical fasteners are good things
See you by the feeders,
