would it work for estimating the weight of a palm. I had to order a crain and I wanted to get the whole thing at once and just lay it in the street.
I may end up renting a crain thats as tall as the palm and take it down in sections. What do you think. Its a canarry date palm. fat and tall

Here is a smaller simpler chart from Yale

Big cottonwood log pick
I used the Woodweb calculator yesterday to calculate a log that we had to pick with a crane today and it was off by about 1000 pounds. That suprised me a bit. The crane operator basically said he wasn't suprised at all because those charts usually are more for estimating.

Turns out the woodweb link assumes 75% moisture (buried in the documentation). Taking into consideration the fact that the difference between the two sources is inconsistent (Sherrill heavier for some woods, lighter for others), it would appear that the real explanation is simply that these tools use base data (lb/cu ft of wood) from different sources.
Anyone have a feel for which is more accurate?
Also, I wonder if anyone uses a "Palm Pilot" or similar handheld device. This would be a pretty simple thing to code in basic for the Palm, and I might consider doing so if there was enough interest.

The weight of an oak trunk log
You folks might appreciate this story. Last week I was cutting down a 30" dia. red oak tree (green). There were three of us working, and I was handling the big saw. The last trunk section was about 72" long. I told my buddy, "We need to make three cuts and make four billets for splitting."
My buddy asked, "Why not two cuts and three 24" logs. Our stoves can both take 24" logs."
To which I replied, "There are only three of us here working. We will be lucky to move 18" billets to the log splitter."
In fact, we could hardly roll the 18" billets, even on flat ground. I firmly believe that the 24" lengths would have been impossible for three men to move by hand.
BTW, I also notice a typo in the posted log weight table, The 32" dia. red oak log should read 351 lb per foot rather than 251 lb per foot as shown.

Oh come on, they would only have been around 600#each
Red Oak Logs Heavier Than White Oak?
Just my WAG.
LOL! I am also a bit surprised that the table lists white oak logs as being lighter than red oak. Dried, white oak is rated about 15% greater density than red oak. Perhaps if green, red oak may contain more sap water because it is more porous, and thus it would weigh more. Thus the table is reporting green logs rather than seasoned logs?Oh come on, they would only have been around 600#each

Large Diameter Billets
My buddy asked, "Why not two cuts and three 24" logs. Our stoves can both take 24" logs."

I usually turn the big saw 90 degrees from the cut, cutting with the grain & quarter (or sometimes more) them till they can be handled easily. Better have some plastic wedges and a sledge hammer so the saw wont get pinched. If the saw is kept out of the dirt it wont dull that bad. Usually the chain is headed for my grinder to be touched up anyway.
Usually, I am using a stihl 066 for this task, however I have used a 029 with great results on the 18"ers. If you are cutting correctly you will soon see 6" long chips flying out of the cut.
Try it, you will be supprised how easy it is!

come on its one of the first things to learn in school for tree care tom trees
Could anyone figure out how much a 58" by 1' section of white pine would weigh?
Volume of cylinder = pi * r^2 * h
weight = volume * density
---------
radius (r) = d/2 = 1'/2 = 0.5'
height (h) = 58"/12 = 4.833'
density of white pine (rho) = 36 lbs./cu.ft.
---------
Substituting into the volume equation:
Volume = 3.14159 * (0.5')^2 * 4.833' = 3.796 cu.ft. of white pine
Substituting into the weight equation:
Weight = 3.796 cu.ft. * 36 lbs./cu.ft. = 136.659 lbs.
Answer = about 140 lbs.
EDIT: Yes, I was bored and hand nothing else to do.

I think d=58" and h=1'
Yeah I've got a slab of wood in my back yard that is 58" by 1'. I flipped it down the hill and it was HEAVY. My forearms sure were sore. 
OK, then it's about 660 lbs. (Good thing I saved the spreadsheet.) Now for some champagne. Happy new year!
