log Weight

[Stephen1]

I am picking up some Douglas Fir damaged telephone poles that I have already trimmed the broken & heavy creosoted parts off. I need to figure how much weight these logs are while I am loading them on my trailer. I have gone to the tool box here and can figure out the weight while in front of the computer. My question, is there a printable table or formula I can use while I am at the site?

Could just figure the volume of the log (length time area) and multiply times the weight per cuft.

Estimate by using the diameter around mid length to account for taper in the pole.

The Wood Handbook will give some values for weight per cu ft.  Doug fir, at 12% is around 35 lbs per cu ft.

I believe the creosote would add some extra weight.

I can see everybody busting out laughing at this, but...... Are the poles pretty uniform in diameter?  If so, I would think if you could get a 1 foot long section, maybe about the middle diameter of the poles, and weigh it, you could then measure the length of each pole and multiply that by the weight of your representative 1 foot.

I like that idea as formulas do not always agree with me. When I built my cabin i used a 12\12 pitch roof, simple, and  it was the only formula I remembered from school.
Can some one give the formula for a round log to figure out volume?

Add the area of each end, and divide by 2.  Then multiply that by the length.  If you keep the units right, you will have the volume.
