Yes, it's hard on chains. The"buckskin" was a"sill log" from a wooden culvert and had a fine layer of silt on it. That's why I under buck on many cuts. It throws the sand away from the cut instead of dragging the dirt through the cut. Terminology: Buckskin - log with no bark, Punching - log covering for a culvert and Sill logs - base to support culvert punching. Wooden Culvert; two logs, the size in the picture, are laid in a ditch across the road about 4 feet apart, then 18" to 24" diameter logs (punching) are laid at right angles on top of the sill logs then covered with gravel to form the road bed.
There was a time when this was my small saw; the real saw was a 076 Stihl with a 42" bar! My nephew in the picture. He liked Huskys.
Terminology; Bull Pen- where loggers meet in a shack where the crews are marshalled for work and have a morning coffee before going to work for the day. There has been much discussion about bar lengths in the bull pen on many mornings before work in the woods. WE are all used to using the bigger saw with 32" t0 36" bars. The short bars being the 28" on my little 57o. The consensus is Kick backs with these longer lengths of bar will get you in the legs where good fallers pants give protection. Put a 16" to 18" bar on the 570, the kick back is much quicker and could get you in the face or neck area.
Yes and with good flow through ventilation. The prevailing winds are east/west and the wood shed lies east/west. East side. West side. The screening at sidewalk level is to duct fresh air to the boiler and boiler room below.
Congrats, that's something to be incredibly proud of! My wife and I are going on 22 years married next month, been together since we were 18 years old so I know where you're coming from. I just hope we can make it as long as you.
