I know you don’t want to hear it. I cut all yard trees and hitting stuff is just part of the process. All I can say is have a lot of extra chains swap out when dull or damaged
I know it happens. I did see some typical blue/black signs of metal in other logs, but not this one, surprisingly. It is what it is. The Oregon H78 for my 20" bar was $19 on Amazon.
Another nice load of wood there. Yeah you slice that one good. I nicked a nail like that a few weeks back. Only dulled one side of the cutters, real bad too. It loves to play hide and seek!
So,.my shed is full. And apart.from about a cord and a half of uglies and shorties of which I need to split about half, and what you see here, all is done. Not too shabby for me,.an echo 4910, and an x-27. Took Monday off to take advantage of the cooler weather because from tomorrow it's going to be a beast to manually split... Saturday 87 F...
From June 2 my second load of logs was done and I had a lot of uglies and shorties left over that needed splitting for the neighbors. They were working on their storage (they built a pagoda thing put the 6 ft tall dog fence around it and wood slat fence around that against the rain). It's 10*10, with pallets. One quarter is the "entrance". They throw the wood in and it's 3-4 ft tall now. So 75 sq ft x 3.5 = 262 cu ft. Not sure how thrown shorties (many 10" or so) compare to stacked volume, but that is 2x128 cu ft. Also two 10 ft long racks, 4 ft tall, with relatively straight pieces of 14-16" long stacked. So I guess I gave them 2-2.5 cords or so. And I found this in a red oak log that had been standing dead. Never seen fungus so.deep green.
