Never have seen one in person that im aware of. They do exist in CT from plantings. I would trade oak for osage or BL. I dont often cut oak due to the drying time.
Thanks for the offer, but got seeds already from a CT member who got some mailed to him by a FHC member. Lots of networking going on here.
I opened it up to check, it was actually just fine. That's something I really like about the cs400, it has a great filter.
Chainsaw's best friend = air hose. I kid you not when I say " I wouldn't even let that saw in my shop without giving it a little air dusting " In it's own way it is kind of good looking though.
On the rare occasion I clean a saw the air hose is my friend. The really oily ones get the pressure washer.
