In my experience, trees are a little more brittle below freezing. Kinda makes sense, trees are mostly water with no exothermic process to keep them warm like we do, water freezes, ice is brittle.

It’s not that simple, and I really don’t think trees split along the fibers and would be liable to chair any more than when it’s warm ;)

Pretty much agree with all this in the cold environments that would be off coast where I have 'logged in' approx 6000 winner SAW hours. The wood is likely just really tough up that way. pretty much you are only going to b-chair if you left to much hinge and you hit with your next row. That's usually Just Pine. Not the Aspen, Birch or Cottonwood...they are bullet proof. Prehaps because they do break off easier? BC Fallers speaks of this and it may be true. (Although I have fell everywhere and in all seasons in BC) Now if you Fell cottonwoods all winter in Central BC and went to the coast the next day to fall the same species of cotton wood that is not frozen wood then you may get killed that day from a chair. Yeah that should be in the book more importantly. BUT it's NOT. Along with anything about falling on the west coast.
Books a guide line.
Big difference between -20c and -40 c
Just like metal, after -35+ things snap.

Right! Trees are endothermic



'Heated from the sun' A heat energy from without.
 
posted too early ....^^^^
Through photosynthesis it brings in a light energy so it's endorthemic.
If it has ice in the tree and it's starts melting from outward warmer temps it's a endorthemic process

How about this one?
The tree cell survives the cold by displacing the water away from the cells.
There is more energy in water than ice but when the water freezes the energy is released into a heat.
Would that not make trees in cold environments exothermic in the winter
How about if I told you a $40,000 heat detector installed in a helicopter to find bear dens so we don't run over anymore with mulchers ..but It just kept picking up the heat of the spruce trees at -30 c in one January?

Getting a good start on setting up our new mill finally after spending 90 days in camp with only 10 days at home so far this year. So sick of spinning wrenches on other people’s stuff. Also brought my new Skidder home yesterday.
 
Every which way. Nothing a triple hinge, tongue and groove euro reverse bore cut can't handle. Ron
About right. Few taps of a wedge and I figured out it needed a little sawing on the face to get it moving. Thank God it was dead calm. Ended up with a 10fter and four 8' sawlogs. Plus 3 more 8' pulp sticks. The tree is completely rolled over in the pic. The hold wood is 180 from where it was standing.

I spent about 1/2 hour last week trying to figure out how to cut the flat places out of one of those. Ended up with 2 12's and 3 not very good 8's but got paid for 'em. Probably made me an extra $.03/hr!

Yeah they can take some doing sometimes to really utilize

Almost did not put those 3 top logs on the load and then got to the sawmill and looked at some of the crooked stuff in their yard and decided I worry too much! They got really low on inventory this winter, not very good working conditions in the woodscrooked.jpg
