I partially heat my house with a wood stove.
A friend dropped off about fifteen large pieces of what I think is cotton wood. The pieces are varied shapes, but about 2 ft. long by 18 in. sq. is an approximate description of the size of the pieces.
The pieces are probably from the base of a very large tree, probably with multiple fused trunks as the grain is very gnarly. I tried splitting several large pieces with wedges but found it extremely difficult. I also tried ripping it but it was very slow, producing fine dust cuttings like a dull chain. The chain cut like a sharp chain when I subsequently checked it for cross cutting. I have two Stihl chain saws, one with a 20-inch bar, and one with a 14-inch bar.
The local Stihl chain saw distributor at Ace Hardware was not very helpful when I inquired about ripping chains.
Does anybody have any helpful suggestions?
