Trailer Pictures!

Sometimes, it is just best to show the methods and final results...

Obsessive featherboards...

Dado blades...

The tablesaw

Output, LOL!

Sides...

Capped tops and back panel...

Sad part.  I just couldn't get the back corners to match.  After a bad measurement, that was what I have to live with.

But the whole thing is going to be functional for the next 20 years, so...  OK.
