Poplar strength in bending

Yes I know I've posted this treadmill question to death, but I'm all about
ressurection.

I never did get a chance to go and get some oak to replace that treadmill
deck, but I got all this poplar sitting around from my table mock up.

Would poplar split and break in an environment like a treadmill? I seem to
remember that it isn't very bendy strong but overall is quite stable. I'm
thinking to myself, "Hmm, I'll get this 13/16th poplar deck installed and it
will feel solid as a rock. Then running on it will cause it to crack and
split because it's bending - better stick to my original plan and use white
oak." Am I being uncharitable here? I think I estimated it was about a 4
foot span between supports.

Plus, there's nothing that says you can't use the learning piece for
something different later on. I'm good at reusing old pieces and looking
through material for the piece with the least waste.

At this point, it would seem to be your best course to go out and try
your ideas.

Endless speculation by those here that are sincerely trying to help
you don't know your talents in joining wood, your knowledge of tools
or their availability, the quality of your wood stock, or your overall
skill level in building.

My personal advice (take it for what it's worth) is that since this
had been bandied about already, why don't you go out to the shop, give
it a whirl with the material of your choice and let us know how you
did?

Not trying to be critical here, but you can work yourself into such a
hole planning the project you never make it to the shop to do the
work.

Well.... you have to learn on something. Better to practice on a
renewable relatively inexpensive wood than something like cherry or
walnut.

Looking forward to it.

________________________________________________________________

On a superficial level I was already thinking this same thing. Because
you're right, I have talked this to death already.

I think in my mind I really hate the idea of wasting trees. I like my
projects to have some meaning and don't like to butcher a piece of wood on a
lark, because to me that's wasting resources and contributing to
deforestation.

What the heck, it's only 8 board feet of lumber.

I'll let you all know how it turns out.

Well the deck is drying now. I glued the shishamole out of it, which on
consideration I wonder was a mistake, but at any rate I have the deck in
clamps waiting. I figure on Wednesday I'll drill holes for the hardware and
mount it up Still need to grab 3 cross braces to hold it together and take
the load off the glued edges.

If it lasts it will be a thing of beauty, but even if it doesn't at least it
won't weight a ton like that MDF monster that's on it now.

You've got it laying around! Have some fun!
