Thank you Planovet -- I'm getting a lot of inspiration from your two pictures. That's how I want to build my cabinets. I've scanned my drawings and put them as a picture in my album. Really sorry about the clumsiness of the drawings, but hope they get across what I'm planning.
My basic dimensions will be 68" across, 30" from countertop to floor, 20" from center of front wall to front edge of countertop, 17" from L,R ends of front wall to front of cabinet (the 3" difference because of the rounded front wall), 12" from top of wall to bottom of overhead cabinet and 12" gap between upper cabinet and lower cabinet countertop.
I also want to build a leftside cabinet that hides the AC panel and shoreline, that juts out from the main cabinet 14" from the leftside wall and 16" from the front face of the main cabinet, and of course the same 30" height as the main cabinet. Then I could put an 'L' shaped countertop across both.
I wouldn't have any shelves inside either lower or upper cabinets.
With all 3/4" red oak stock, I think my cut list might look something like this:
For the upper cabinet: (there is a 2" drop from the main trailer roof to the top of the front wall, approximately where the top edge cap is outside. So I need to build the front face of the upper cabinet 2" deeper then the height of the front wall would suggest.)
(2) 68"x2" rails
(4) 10"x2" stiles
(1) 68"x20" panel to be the floor of the upper cabinet.
For the lower cabinet:
(1) 32"x2" rail (top of front face of main cabinet)
(1) 32"x2" rail (bottom of front face of main cabinet)
(2) 16"x2" rails (top and bottom of left cabinet)
(2) 26"x2" stiles (left, right of front face of left cabinet)
(1) 26"x2" stile (left side of front face of main cabinet)
(1) 26"x16" stile (right side of front face of main cabinet, assuming 14" door opening)
(1) 30"x20" panel (right side of main cabinet)
(1) 30"x14" panel (left side of left cabinet)
and enough cleat stock to screw this in place.
Where I'm getting confused is in things like, how do I figure in the overlap needed to butt the left cabinet against the main cabinet? Does assuming 2" rail heights and stile widths allow for hinges, cabinet snaps (not sure what the hardware which allows the doors to snap shut is called), proper door sizing, room for the pocket screws, etc?
Also, is it reasonable to build only a front and bottom to the upper cabinets, but leave no top or sides? Just cleat the front face and back of the bottom to the walls/front of trailer and that will do it?
Thanks in advance for your advice.
