How to set up a drill press for compound angles, an investigation
So, I’m stuck trying to get the drill press set up for truss pole seats (They have both a “spread” angle and a “rake” angle that need to be set). I couldn’t figure out how to make my CNC’d jig … Continue reading

Rainier Watch
After a couple weeks of clouds, rain, and wind, last night was clear and cold under a waning gibbous moon. Temperature this morning was 28 degrees. We are in the “too cold to rain” part of the year, which I … Continue reading
