Cast my vote for the "YES" pics! I only wish I had taken the time to document my build. The plans Formica has produced are spectacular. Would have been nice to have them so I wouldn't have had to take my factory Belle out of commision during the process as well as had to run in and out in and out to remeasure, check, etc. There were so many little 'gotchas' that I can now look back and say 'phew-ee, glad it's over....but at the time it was rip roaring fun. I think the hardest part was keeping the fine wood 'fine' during construction. I used Elmer's Contractors Glue - the 'Pro-bond'. Tried several other types.....all suppose to be 'contractors grade' but always came back to the Elmers. Went on the smoothest, not too thin, excellent adhesive properties. One thing that really helped was using an air brad gun to set the initial tack. Glue, press the pieces together and clamp, clamp, clamp. I must have purchased 25 clamps of assorted sizes. Corner clamps, pipe clamps, c-clamps of many different sizes and shapes. You will have to get very ingenious with the construction of 'jigs'. to continue though, glue, press together, clamp, hit it with a brad nailer, drill then screw.
I wanted to answer some of your final measurement questions but was confused about exactly what you were referring to by 'baffle board'. Plus, subsequent posts pretty much nailed all the questions. If there are any further measurement questions or requirements, let me know. "Yes', the grilles lay against the angle of the doghouse on the inboard side, and are held in place on the outer sides by 1/2"x1/2"x6" pieces of wood that are screwed from the top and bottom of the bin. So if you're looking at the top (or underneath) of the bass bin, you will see the screw heads holding the angled side of the doghouse and these pieces of wood. Kind of an "M" pattern.
I will print and take home your latest AutoCad drawing and review against my factory Belle for accuracy.
