Awesomness on the interior latch!

The boxes will stack so much better without and exterior protrusions! 

So that dowel maker, you just chuck up a timber in your drill and shove it in? 

I have a dowel plate for smooth dowels, same hammer approach, but was considering something more "refined". That was until I saw I could buy the infernal things for dirt cheap, at least in 1' lengths and <= 1/2" diameter. Some poor sap sitting in a tent even sanded them smooth and round for me!
