@Skeans I do like the idea of an undercut but for me I just fell more comfortable and in control of the direction of fall with an open face or a conventional cut. I have been cutting another 8-12 inches off each bottom (cutting off the outward cone?) so I can get my board on a flat surface when ripping so waste isn't much of a big deal at the bottom.
Thank you, and yes, the attempt with the post ripping was to leave just the red center on the cedar (does not rot like the yellowish sides). So I have 4 rough cut cedar "boards" left from each beam. Thinking on using them for a door or flooring possibly.Are you taking the round logs that are a bit larger than you need and taking off 4 sides so it ends up square? Does this leave the heart of the tree down the center of the board? Just an observation, I don't know enough about it to understand what kind of impact this has. The ripping did come out nice.
Nice buy on the saw which then turned into a lot of great work on the playhouse!
