I just made my first purchase from Surrey timbers this week, based on their involvement with your world of woods videos. Due to the snow, I haven't actually unwrapped the piece of Zebrano, however I can confirm it was an excellent and quick delivery and well priced piece. Thanks for putting me on to them, I'll hopefully use more in the future.

I’ve always worked with specific gravity on kerosene based fuels and standard day atmospheric temperatures. Even though I understood water on wood and read John Harrison’s book “Longitude, ” I haven’t put much use in specific gravity on wood until this moment. I’ve worked on aircraft since high school but never used specific gravity at home until I ran out of heating oil fuel in my home while trying to save money on the heating oil market and a Nor’easter Storm come though and lost several inches which made a difference with the standpipe in my oil tank. That night my family and I used electric heaters, firewood and blankets until I was able to get four 50Gal plastic drums and fill up my tank with diesel full. A lesson learned when needed most. I changed to natural gas that Summer and now I live in Southern California and kerosene based fuels are only used for aircraft when I’m working with it. Thanks for this reminder. I’ll treat wood much differently now.

YAY! Science! Honestly, though, the information at the end about the application of specific gravity to structure weight was the best nugget of knowledge. For myself, specific gravity was what I measured to determine the alcohol content of my homebrew.

hm :) need to get a block of greenheart for making yet an other carving mallet. i like the sinker woods :D i usually calculate density simply from measuring size, calculating volume and then putting the piece on a scale. if anything has a density of over 1 its suitable for mallet heads :D

Hi there from Portugal,
Nice :D
Obrigado(Thanks)

Could you please give the equation to find density of wood log(measurements in cm)

Thanks Mitch, all totally over my head mate. HaHa
