Beveled timber

That's definitionally correct but that also places balsa and poplar in the "hardwood" category, neither of those are particularly hard.

Don't get me wrong, I love poplar, it's a fantastic wood, probably the best to start using if you're starting out working with, but there's no way I would use it as coil dunnage

 

I don't have a great immediate test but for dunnage the thumbnail test that clausland mentioned is probably the easiest way to see if it's appropriate to put real weight on

 

That kills me, that's a high grade pine piece, very little warp, but it's still pine and certainly has no business being stood on edge as a 2x4 for moving steel.

 

It's really simple. When you will feel the weight difference. No doubt about it. If you can toss it around easily, dont put it under anything heavy.

 

Most, but not all. Tamarack loses it's needles in the winter...

 

Your probably right?

I just learned that a couple years ago and I’m almost 50. Never dawned on me till I heard it tough. Huh

 

After further review I guess it has something to do with weather or not the seed has a coating?

 

Here is the solution, one hell of a price...

 

I learned a little about lumber while working at a lumber company. We would sell rough saw. Lumber for dunnage and pallets all the time. You want dense hardwood for dunnage. Such as oak, ash, or walnut. Examples of soft hard wood would be aspen, birch, or cottonwood.
