Angles and Holes

protractor What did I do on the cart this week? I finished installing the septic system. It has some leaks, so I need to fix those. I cut the floor to size and drilled holes in it to accommodate bolts and plumbing tank vents. Then I started making the rafters. These are cut in a tricky shape, as you can see. Basically I'm ripping down a 2x6 to be a 2x4 but I have fancy joinery at each end. That's what the protractor is for.
