I rolled a 30" ash round over to, and onto the beam of my splitter two weekends ago, and I figured that was around 400 lbs. That ash tree didn't even leaf out this summer, so it's relatively dry compared to that oak. No doubt this wet green oak is well over 500 lbs.
I obviously left my glasses on and fat fingered my calculator yesterday. I come up with 674 lbs this morning. Sticking with split count.
What are you using for diameter?...even using a diameter of 36" I can only get to 560# (using 61# per CF/green Red Oak)
estimated weights for green oak are all over the place - just like drying time. 5,000 pounds for a cord is common, but cubic feet estimates range from 85 to 45 pounds. WTF maybe some of these "wet" estimates are based on taking dry weights and "calculating" the weight of the water back in ? How much do you calculate back in ? 30%, 40%, 60% ? I went with a 32 inch round figuring the bar length spread across the round is actually 30-31 inches. My estimate is a more conservative minimum. and probably off by a bit . LOL
Yeah this is all just a crap shoot really anyways, since we don't know the exact type of Oak, alive or dead, etc...and the weight was just calculated averaging 20 splits too, so...stinkin big boy, no matter how you slice it! I know the weight on these big ones adds up quick! We had a big Maple log that had to be hauled off from a parking lot a few years back. 10.5' long and ~5.5' diameter...our 5k # rated forklift wouldn't pick it! Had to lift the dump bed of the trailer to kinda tip the log (it was standing up for carving...but was partially hollow so that didn't happen) into the trailer bed, lower it down, then push it the rest of the way into the trailer. We were guessing it to weigh 7-8k # then...
Ok so here are the results: 121 splits. 20 random splits weighed 122 pounds so the best estimate I could come up with is 738 pounds. Glad I decided to noodle in half before using the log lift which says not to exceed 500 pounds.
