A neighbor has a couple sheds built entirely of cottonwood, and about 100 years old.  But the shingles are not cottonwood.  Just framing, siding, and flooring. If you use it for trailer decking, should you oil the wood before installing?
I use crankcase/tranny oil on trailer floors, done when woods dry. Linseed oil, boiled or not is organic and feeds the little fellers that grow on wood. Protects but feeds, so best if it's used to include something in the mix that prevents that growth.
Early in my log homes life I mixed up a wood finish formula found in a U of AK log building pamphlet I had which used linseed as a base- maybe in ok in AK, but in KY you get mildew!

Got a little excited when I saw this post, I have a bunch of standing dead cottonwood so I sawed on up and made a vanity for my wife, also sawed a bunch of green wood up for my brothers lowbed decking and he says its holding up great, its been a few months of abuse now.

i just got a gallon of copper naphthenate, to treat outdoor wood.  will not be "pressure" treated, but the surface treatment should impair growth of mold and other organisms.  copper care is the brand, from amazon.  outside but off the soil is ok.  i hope this product will help on my hackberry pallet runners.

Doc thats exactly what they are, other than only 4. I initially built a set to set a old pickup camper on then realized they were way better than my old 2x4 ones and way lighter than my grandpas old timber ones, I even built him a set after he seen them, dont need a tractor to move them lol and theyre surprisingly strong  ;D

even my 7 foot ones with 2 x 6s are easy to carry, center on my shoulder.  and the leg brace is plywood on the outside of the legs, so they will nest one on top of the other as well.  crazy minds think alike! :)

Yesterday I was dead stacking some cottonwood that was sawed and stickered this spring. Some was sawn into 1x material and the rest was sawn for 2x framing lumber at 1 1/2" thick. Anticipating some movement I sawed it all a little extra wide so I could rip it to final width on the sawmill after drying. As expected most of the pieces did crook but not too bad. Should be plenty of extra material on most boards to rip them straight. Otherwise it dried nice and flat. Only a few pieces really misbehaved. There was some shake in the logs which ruined some boards but that was expected too. I should be able to save some shorter sections from the shakey boards.

I've sawn cottonwood before and some of it almost tie itself in a knot while drying so I was a little worried. But those were edge grown trees with off center piths and many of the logs were bowed. These were straight and clear with centered piths. Sawed super easy (other than handling the very large and heavy logs (30+"@12-15'). I'll be on the lookout for more as general utility/framing lumber isn't easy to come by around here.

The 1x boards probably stayed the straightest:




The 2x material showed a bit more crook. The two pieces to the left have opposing crook and were probably average, so it wasn't all that bad. Most were sawn around 7" with 5 1/2" being the intended target after straight lining





Only a few had fatal defects:





Some of it was very pretty coming off the mill. Will be interested to see how it looks after it's planed and finished:
