Larch weights

[timbernut]

Hi, can anyone tell me how to work out the weight of a larch when fresh felled and how much weight it would lose in a year of being on the deck, they are de limbed some full length (between 20m and 30m) and some cut to 5m, any constructive input greatly appreciated😄

0.85 thus 1m3 weighs 850kg green / fresh felled. Down to 0.4 after 2 years drying in the round. APPROXIMATE figures...

Cheers, is there a book or some such that gives weight to volume of all wood types or is yours the voice of experience?

I thought Larch was higher than that 1.11 for EL and 1.2 for HL/JL.

This is what you want all you ever wanted to know are more. And enough maths do get you a GCSE if you like that sort of thing.

 

TCD has sold a lot of Larch so i'd guess his figures are spot on but I've just checked the book and it says mine are right.

Sorry, what is what I want, have I missed summat? : )

Other way round. Blue book is pretty reliable and euroF abide by it i.e 25cuM on a lorry will weigh iro 21.25t. I'm processing some JL at the moment that was decked over a year ago and left rigged out in pole length; my goodness is it heavy. Bark falls off but the sap is spraying so much I keep thinking I've got an oil leak in the head.

Oh dear memory failure HOWEVER; as I said 0.85 / 1.15 is definately being applied in this part of the world... Hmmm, not complaining!!!

Thanks guys, that's really helpful, I'll have to get a copy ASAP as I've got to work out what we felled last year as company comin to shift it are sayin there's about half the weight of what bottom estimate was at time of felling😕
