I just had the pleasure of videoing a large Ponderosa Pine being sawn at the all steam powered Phillips Brothers Mill. This, they believe, was the largest they have attempted at the mill. It measured 60" at the widest part of the stump. The tree experienced extensive storm damage last winter, making it necessary to take the remaining part before all was lost. It was mostly sawn into large planks and will go to a specialty home and furniture builder.
Sorry for the length of the video. I had a hard time finding parts to cut from it. Hope you enjoy it.
