Started with just a dry fit..
Case Work, dry fit, bottom frame.jpg
As this frame was labeled as Bottom frame...

Got out the screws, the bottle of glue, a BIG square..and something to drive the screws with...Big Square?

Since I am working with Frames, might as well use a Framer's Square..and worked my way up towards the top of the case..
