Go to about 7:10 on this video to see the use wood to hold the tank up..
And they're careful about the shape of the wood and orientation of the grain, believe me! What driveway wrench can say the same thing? For the most part, we're hobbyist mechanics, not engineers.
Wood is an excellent engineering material - strong, light, and easy to form. However, it's also PAINFULLY easy to screw up with!
I'm familiar with the myriad uses of wood in engineering - from Balsa to lignum vitae
. I'm also familiar with how it's designed and engineered when used - you don't think they just just any old wood block to hold up tanks or ships in drydock, do you? Or that they just run down to the Home Depot when they need more? Trust me - most of the stuff you find in the hardware store is rejects
from high-strength engineering uses, or stuff that they know would be rejected, so they didn't bother to submit it!
