Volume of Log - Calculation
I would like to have someone check my rather simple way of working out the cubic meter volume of a log.
I assume that 2piR is the formula, so
300 mm diameter log = 2 x 3.14159 x 150 mm = 940 mm square, or 0.094 m cubic over 1 meter.
If the log is 6 meters, am I right to assume 0.0940 x 6 m = 0.55 m cube?
When I use the calculator that is off this site, it works out near to.
If I buy the log at $16 per meter, then I'm looking at $177 per cube?
This is where I fall down, seems way too cheap, when the same timber in 100 mm x 25 mm is at $3,740 per cube.
The price list states it is sold "per lineal meter, 300 - 349 large end diameter $16.00 per meter". I am assuming I'm looking at this the wrong way.
I also need to know the conversion rate of cutting this down, I am right to assume a 60% recovery and 40% waste as a good starting point?
I know this depends on the method and machine used, however I am looking for a "rule of thumb".
Does all this sound about right, or am I taking the wrong path?
Thanks in advance.
(I've used the word ASSuMe 3 times in this, obviously I have no idea :D )
