Thanks, It should be very nice when I am done with it. I have a plan drawn up (well, not really a plan, more of a sketch) that might help you out. I scanned it as a pdf and uploaded it to my server. I did not mock it up with doors, but I plan to make some cheap raised panel doors using MDF for the insert panel. I plan to paint this as it will mostly be MDF. The "shelves" for the pen boxes are not to scale, I plan to fit as many as I can based on my reach height. The depth for the total cabinet will be less than 10" deep (with door) The left side will have shelves that are maybe 4" to 5" deep to allow the left door to have peg board on it. The peg board will hold the same peg rack system I have for letting finished blanks dry on the top side and the lower half will have wood bracket holders for my extra lathe rests. The center drawer depending on left over room may have a small storage pocket on each side and a narrow one along the bottom. I want the paper towels to feed out the bottom. Anyway, I hope this clears it up a little more.
