a question for the woodturners

[se7enthdevil]

i've been turning a lot of wet wood in to rough bowls recently and just wondered if anyone had taken notice of just how much weight some timbers loose?

 

the question is

 

what timber looses the highest percentage???

[treesrus]

i should think Acer and Salix, and maybe Betula.

[slackbladder]

My guess is Poplar

So what's a fair guide to percentage of weight loss from green to dry?

This any help?

Holm oak holds loads, and when you have roughed it out spin it fast and the water will fling out across the ceiling!

beau,

the drying rates of the different grain orientations i'm already aware of and am not surprised by the results you arrived at, i'm more interested in the drying rates of different species like oak, beech, catalpa, rowan and any other species you can think of.

 

for example, hornbeam lost between 25-30% but laurel only lot 20% max.

 

my two field maple have lost 30% but the winner so far is liquidambar at 35% and its not finished yet.

 

i am interested to know if any one had taken note of the percentages of weight lost by roughed out bowl blanks before.

Might be a bit of a cheat, but the wettest surely has to be Bog Oak, straight out of the ground. Utterly saturated, I've half recollection of someone saying from fresh to dry a cubic foot gets rid of 3.5 gallons of water. Turning it in that condition must be like standing under a rotary shower.

Otherwise, poplar and willow must be top candidates.
