I used PL Premium on my oar laminations. It has held up really good
so far. Only problem is that it swells a little and leave a very
visable glue line. My son has the oars in CT. now, so he'll be giving
them an old fashioned New England testing, bashing some rocks from
tome to time. In Fl. all I have to worry about is the coarsness of
the sand :-)
I think I will try some of that Titebond II next time around. Does it
swell or is it more like an elmers when hard?

to temp are well taken.
Further, anyone who hasn't bought their glue already might want to
try Titebond II, which only warns against use below 55 degrees,
rather than 70. Makes it a less dicey proposition.
We had a little thread on Titebond II last year, and (I think) the
consensus was that it's just as strong as Weldwood. Anyway, I love
the stuff -- easy to apply, premixed, pretty cheap, easy to clean up,
etc.
All best,

This is just for information.
Yesterday I experienced my first failure with Weldwood glue. Major problem:
cold temperatures.
I'd heard the warnings not to glue under 70 F and had always heeded that.
However, I had a pair of oars cut out and was dying to build them up. So,
reasoned I, I'll make a little tent of my guest bedroom room divider and
place a little heater in there with the oars. (BTW, we live in a 100+ yr old
house, and there is NO keeping it abouve 70F in the winter unless one is a
lottery winner, and I am not :-) Outside temsp were in the 20-45F range
during the clamping days.
So, I mixed up the glue and slathered it on, remarking to myself that it
looked a bit funny....sort of curdled. It was a new container, so I ignored
that warning, thinking it was just "different". I tented the clamped assy and
got it up to 85F or so and left it clamped for 12 hours and then did the
other one.
Next day was a bit warmer, so I tapered the lower looms on both and made some
clamping fixtures for 8-siding and holding the blades for shaping. Next day I
got out the drawknife, planes, and belt sander and rough shaped one of them.
Looking pretty good, though I, and took it inside to show my wife (who never
really is interested in my artificing, but makes a good show of it). Well, I
noticed a bit of separation down where the pint of the loom overlaps the
blade and so I decided to do the old test on it. I put the end of the blade
on the floor and pressed pressed downward on the mid portion of the loom.
CRACK...both the side laminations split nearly completely off. DANG!!!
I went out to the shop and got the one I hadn't shaped yet and did the same
test with the same result. Oh, well, only US$8 worth of materials and maybe 6
hours to that point. Cheap lesson, I'd say.
I missed two important points. First, that glue mix curdling was telling me
that not only was the ambient temp. to low, the glue was too cold. Second,
the wood was cold (never thought of that) when I applied the glue. Putting it
in the heating tent eventually got it up to appropriate temp, but by that
time, the damage had been done. I don't know the chemical pr0cess involved in
this glue's curing, but I'll bet that most of that had occurred before the
temp. got up enough to matter.
I'll probably never again attempt to glue at those temperatures with
Weldwood, but if I do, I'll warm the wood and the dry glue in the tent for a
long time first, and I'll use 80F water to mix with.
Hope I ahven't bored everyone; I thought this experience was worth sending to
the list. Anyone want a decorative oar??? :-)
