A carpenter ant infested green ash crotch being milled using a piece of heavy aluminum C-channel on sawhorses as a guide for the first cut.  Also the standard 20 inch bar on the Stihl 039 has been replaced with a 24 inch bar and a rip-cut milled chain.  The extra four inches and a new bar make a big difference in getting good true and flat cuts.

It would have been better had it not been filled with a colony of carpenter ants, but still nice wood.

A little better towards the edge, just not as interesting.
