cord to loose again!

[Woodworks]

OK been out to weigh some fresh cut oak. This was felled on the 13th of October. A full crate takes 1.13 cubic meters and this crate is pretty nearly full so just over a 1 loose cube of logs. The crate plus straps and wooden block etc weighs 75kg. So I make that 530 Kg for a generous cube of fresh oak which is as heavy as it gets! In reality most of us are getting mixed species that has usually been down some time.

 

If you can only get 1.4 to 1.8 cube of logs from a a tonne of logs I would look at your measure of a cube and if that's spot on your supplier needs to check their crane scales

when I was weighing it I was getting 490kg for a 90x90 bag

Have a look at the "Wood Fuels Handbook" http://www.fao.org/3/a-i4441e.pdf

 

It has some interesting conversion factors along with mass densities at various moisture contents. If I understand it correctly a neat stack of roundwood logs with bark, will comprise 30% airspace.

 

Handbook pdf is ace, hadn't seen this previously. And it's free:biggrin:

It gets a bit techy in places but it's handy. I also found a free spreadsheet that has all the density and calorific values for hard and softwood, solid, split, stacked and loose. I'll reply with a link tomorrow if I find it.
