Swinging bench frame - PEM BB roundwood.straw.benchframe

This is a badge bit (BB) that is part of the PEM curriculum.  Completing this BB is part of getting the straw badge in Round Wood Woodworking.

As your roundwood construction skills are improving, it's time to make things that are elegant while still being sturdy.  How about one of those fancy swinging rustic log benches?  Or a swing set?  Let's make a frame for a swinging bench style application!
