Ok, stupid question time... I read about "ca" in all the gluing
discussions... guessing that it's the older, "carpenters glue" or
something, but I don't want to dent my learning curve with a
misconception..

Flamers welcome, as long as one of you fine folks answers my stupid
question.. *g*

Cyanoacrylate glue. Also known as super glue, krazy glue, zap, etc.

Thanks, DJ.... my education continues!

Be advised, though, that the CA glue that we turners use is NOT the Krazy Glue
or Super Glue you find in drugstores. Those are watered-down versions and do
not work very well for our purposes. Buy Hot Stuff or Starbond, which is pure
CA and comes in various thicknesses: Thin, medium and thick (and a couple in
between with Starbond). They also have spray-on accelerator which speeds up the
curing. Care must be taken with the thicker viscosities in using the
accelerator as it can cause the glue to cure too fast and it can foam up and
turn white.

Right, Jim. I also advise special care with the thin stuff. It can easily
flow right through the joint and down between your fingers UNNOTICED. Then,
when you hit it with the accelerator, everything cures, and you have a bowl
attached to your hand, and your fingers attached to each other. DAMHIKT.
Also, don't ask me how I know it can happen repeatedly.

One _more_ reason for giving a quick spritz with the accelerator prior to
applying the glue.

Back in my RC model-building days, having glued my fingers to each other
repeatedly, I finally invested in some stuff that applied like handcream and
prevented CA from bonding to my skin. Can't for the life of me recall the
brand name, but it was effective. Of course I no longer have any tactile
sensation below my elbows. :-)

Anyone know the name of the stuff?

it must be really difficult to type with those bowls stuck to your

Probably just a barrier cream. Google those two words...there are a
number of them out there.

One _more_ reason for giving a quick spritz with the accelerator prior to
applying the glue.

A word of caution here........... when using an accelerant, its not an
uncommon sight to see a tiny puff of smoke come from CA when spritzed,
I've received several small but painfull burns to my fingers while building
balsa models

Which, of course is a different case, where your fingers are deliberately
involved. Still makes sense to spritz the back side of a crack to stem the
flow and avoid casual finger trapping.

Now, does anyone know what it is about punky wood, especially punky knots,
that causes the same rapid and odorous reaction even in the absence of the
accelerant?

Probably moisture trapped in the punky area.

Interesting question: the commercial accelerants are (or at least used to be)
basic organic materials. So my guess is that some of the wood decomposition
products are basic enough to set off the same reaction. (I'm a chemist w/ no
forestry/botany background, note that this is a guess, not a gospel)

^^^^^^^^^^^^
That might be part of it, but I recall reading in some previous discussions
that some vegetable fibres, like cotton, can trigger the reaction. This
might also be related to why CA glue practically ERUPTS when it is flowed
into a pile if sawdust or woodchips.

I once made the mistake of spreading some CA glue with the corner of a
cotton rag, wrapped around my finger. The stuff cured very fast, bonding my
finger to the wood, and generated enough heat to raise a blister. (There is
no way to let go of CA glue that is curing.)

There is some information on Russ Fairfield's page
http://www.woodcentral.com/russ/finish4.shtml

where he states it is the cellulose that acts as an accelerator. This is
the section titled:
Hardening The Wood with CA Glue

Yep, I read that, too. So why only when punky? Lignin eaten away, maybe?

May be it has something to do with air in the wood. Punky wood seems to be
much more porous than solid wood. More area of exposure to air for the
glue.

I think that's the most logical, given the sawdust phenomenon. Weird stuff,
that's for sure, but tough to beat for tightening up a hairline crack.

I used to use something called Git Rot to repair punky wood in boats. It
wicks into the wood and sets up hard.
It's a type of epoxy.
