Hi John,
According to my inherited 1941 Machinery's Handbook list of "Average SG of Woods (Dry)":
Weight per cubic
SG inch (pounds)
Live Oak: 1.15 0.042
Red Oak: 0.75 0.027
White Oak: 0.80 0.029
Hope this helps, though these figures are supposed to be for dry wood, so I'm not sure what "live oak" is.

If it's from Machinery's Handbook, they could well refer to N. American species ???
Not sure if they're the same as European Oaks.
Silky Oak is a eucalyptus .... IIRC .. :scratch:
Long time since I did any wood butchering

That's why I suggested weighing an offcut of the same wood, the volume of which could easily be calculated.
To add to the confusion, Selly Oak is where I spent 3 years at university in Birmingham. :)

Hi
Had a bit google came up with this
SG of birch ply is 0.67
Pattern weighs 2.2 Kg
Formula is
Weight / SG = Volume
2.2 / 0.67 =1.474 Litres i assume
I can melt 3 litres so it should not be a problem :Doh: :Doh: :Doh: :Doh:

Problem is that 2.2/0.67 = 3.28 !
