Nope, no clamps. I dunno Steve, I think you might want to look
over the article. I didn't see the article itself on-line, didn't
bother looking either, but the magazine article says there's videos
on the testing on-line.

Surfaces prepped according to manufacture suggestions.
I just tried ipe with the recommended yellow glue it still does worse
then gorilla glue. but gorilla did not do perfectly either. I have
had joints break using it too.
but it is not as critical as I build my planes a different way now.
I've used very little ipe so no real experience to pass on. I'd think
would be a place for the rsorcinol two-piece glues, maybe?

I've never been very satisfied w/ the urethanes for anything, frankly.

I did notice there are several letters to the editors on the article
in the last FWW taking them to task for several things -- the basic
answer was on the lines of my main complaint -- "Well, it would have
been too much work to do whatever..." The problem of a magazine
trying to undertake what really should be a longterm research project
and make it fit a cover story format. Just doesn't work well.

Seems to me that some classes of research could be conducted in a
"contrulled service utilization" format. They have furniture in their
offices, desks, tables, chairs, etc. So replace the factory made stuff
with test articles. Glue up the drawers with one side using one kind of
glue and the other using another, that sort of thing, keep careful
records, and after five or ten or thirty years they'll know if any
particular glue is having problems with that particular kind of wood.

In one sense it's not as good as a laboratory full of test specimens
being carefully aged and loaded under controlled conditions, but in
another it would be a good "reality check" on the lab results.

Certainly one way to approach it. There is a pretty good body of
evidence that hide glue works pretty well for many applications, for
example, and that "regular old wood glue" is quite strong enough for
edge joining from that kind of experience...

Two things I'd note (neither intended as criticism, just noting...

First, there is a significant amount of research from the FPL and other
organizations available under controlled testing which addresses much of
the questions the FWW article was after.

Second, for anything other than the casual woodworker or ordinary
production, the question posed to these people or the manufacturers can
often be addressed for specific situations. For specialty applications
or high volume situations it may well be worth such an effort.
