I am not sure what you mean by large diameter. We bend conduit all the

Right, but even to bend 1" pipe, surely you use a "bending device" (my
family would disown me for that... both father and brother are
electricians and I spent a few summers as an electrician's helper, but
am a complete nerd about practical matters... so, I don't recall what
that fulcrum thingy is called). Anyway, I'm guessing that the larger
diameter pipes cannot be bent, readily, without mechanical assistance.
Hence my thought that, if a human can't readily bend it, a 100 pound
kayak is not likely to bend it either (even at 50 pounds times, let's
say, 30 inches). But, as I say, I'm not the electrician, I'm the geek.

And all US are like Archie!

I would suggest that you take a piece of pipe, extend it out the
desired distance from edge of workbench, attach stationary end, and
then start loading the extended end with weights to see when it bends.

I know that if there was a piece of conduit sticking out from the side
of a building, 10 stories up, I would not trust it to step out on it
with even a portion of my weight. Now obviously this is not the same,
but you could still get hurt if the extension collapsed and you caught
the full weight of the boat.

Your 1x4 would probably not be strong enough, but again you can test
it.
