we have municipal recyling in Ottawa. we put our plastic containers in
platic bins and put them out for pickup on garbage day. so its a simple
matter of walking around the neigbourhood on garbage day looking in
people's plastic bins for plastic containers. I don't use epoxy but do
ocassionaly find need for discarded plastic containers.

Titebond is "aliphatic" glue, yellow carpenter's glue, not water
resistent. I don't know what Titebond II is but one of my home handyman
books says there is a water resistent variety of aliphatic glue available.
Maybe that's what Titebond II is.

The shear strength I posted earlier was for Titebond II from the Lee Valley
Tools glue guide. It says Titebond II is only good for 3 freeze thaw
cycles so I wouldn't use it on boats up here in Canada.

Well I had to learn the hard way "It says Titebond II is only good for 3
freeze thaw".
Further more, the temperature variation like near freezing at night to +
20-30C during the day will eventually cause ungluing.
I have also use LePage exterior glue with similar results.

shear strenth 3,750 psi. water resistent but not waterproof. pot life

shear strength of epoxy is 15,000n psi and its waterproof.

It happens I volunteered to reinforce the folding leg joints on some
church tables. To replace the two wood screws securing each saddle
on the legs, I used a metal insert with four woodscrews, and two studs
to hold each saddle. I was interested to glue the metal to the table's
underside too.
The strongest (advertized) tensile I could find in 2 part 24 hour
epoxy was 4500 psi. I usually find shear is a fraction of tensile for
the ordinary run of materials... Where did your data originate?

Brian Whatcott Altus OK

opps, my mistake. "Shear strengths are maple to maple blocks", not birch.

the epoxies tested are "G1", "G2", "Cold Cure", "205 West", and "206 West"
the West came out slightly lower at 14,000 psi.

Yesterday, I was applying two by four doublers to one or two rafters
and perlins in the roofspace of the homestread, cracked or broken
after half a century's service. I left one doubler stud overnight,
with some Titebond carpenter's glue applied to one face.

This morning, I noticed I had left a fender washer on the glue face,
and the glue had set 15 hours later.
I tapped at the steel washer's edge to no avail, and finally hammered
it off. It came away with a surface layer of softwood.

I was more than impressed, not expecting such good metal/wood
bonding performance from a one part white resin glue.
It claims to be the strongest wood glue - and water resistant too,
but not for use below the water line.

Brian Whatcott Altus OK

I think the ballots are in, and the majority of posts concur, it just
ain't good for boats..
