To All:

There are times when you need to put something together fast, often
while HOLDING the parts in positionby HAND, such as when you are
making a jig or fixture. Many times the fixture is made of whatever
wood you happened to have available.... 'good' scrape, if you know
what I mean. But the jig or fixture itself is NOT scrap -- you want
it to hold up, often for a span of YEARS. That's when you reach for
whatever quick-curing EPOXY you happen to have on hand.

I've previously mentioned that I use several different adhesives,
selecting them according to need, cost, availability, temperature and
so on. STRENGTH is never an issue since ALL modern adhesives are
stronger (in shear) than the softwoods normally used to build an
airplane (or even a jig :-)

If you will go to...
http://search.harborfreight.com/cpis...?keyword=epoxy...
...you will see several epoxies, including Item# 65048 and Item#
92665. The latter is often on sale for 99cents and is super-simple to
use, thanks to its 1:1 mixing ratio.

If you remember to apply the adhesive to BOTH surfaces... and give
them a couple minutes of 'open' time, they even work on hardwoods.

Don't take my word for any of this. Do your own tests and base your
opinion on that.

-----------------------------------------------

One major caveat:

Do NOT use quick-cure epoxy for PERMANENT bonds!

It is fine for temporary structures, such as jigs, but would be a
disaster if used in anything like wing spars, skins, ribs, etc.

It will disassociate in time into a jelly-like goo, with no strength.
