HATCH FRAMING ROUGHED OUT

New day.  Got home soon enough to rough out the timber for the hatches and clamp them down to scribe the bevels where they intersect.   I'm leaving all of the final cutting, fitting and gluing for the weekend with a good night's sleep under my belt.

I'm going to groove the top faces of the fore and aft rails for some gutter action under the plexiglass hatches.  I'm going to leave the slot under both ends open for routing lines and ventilation.  I'll have a chunk of round pipe insulation cut to length to stuff in each end If I need to stopper the airflow for any reason.  Jim showed a separate ventilation hood under the front windows, but i see no reason not to make the hatches do double duty here.
