No, where was your pictorial?? I just had to think about it for a while. I glued the backside together first, keeping the edges flush, and then I glued the front and top baffle on. I had to use those little spacers because the pressure from the clamp made the board want to slide inwards...
I love that Elmers Probond glue, super tough! Once it bonds in 20 minutes it breaks the MDF!
