Nice job on these! Several questions if I may.
1. Can you share some of the dimensions you used so as to minimize waste?
2. What type and thickness plywood did you use (looks like 5/8 AC)?
3. What did you make the door frames and inserts from?
4. How did you cut the female french cleat on the dividers so that all matched exactly?
5. What kind of jig did you use to drill the pin holes for the shelves?
First off, let me say that I am a mechanical engineer by day, so I like to design and over design things. I spent over a year working on this layout in my spare time here and there. I used a program called Draftsight, which is very close to AutoCAD (and in fact saves in the same format). I can post the full design layout if you would like, but since I had all of the pieces drawn up the layout and waste was a little easier.
1. I laid out all of the cuts (with a 1/4" excess) on the 4x8 sheets of plywood. There was a considerable amount of excess, but I have plans to make one more single cabinet above my bench with the leftovers.
2. The face frames and the doors are 3/4" birch plywood (cabinet style). I minimized the use of this since it was $50 per sheet. The top and bottom shelves (above and below the dividers) are 1/2" general grade plywood. And finally the interior shelves and the dividers that attach to the french cleat are 23/32" general grade plywood.
3. The door frames are 3/4" birch plywood (cabinet style) and the inserts are 5mm plywood. The 5mm is for linoleum floor leveling.
4. I laid out each of the french cleats on the panels by hand and cut them individually with a jig saw. When they were all complete I stacked them together and made sure they lined up.
5. I use a Kreg jig, I figured it was worth the money rather than having to lay them all out by hand. I kind of wish I had used shelf standards in the 2 bays that have adjustable shelves. I think this would have been easier and stronger,but I can always switch to these if the holes turn out too weak. The holes and pins do not hold really well in the plywood.
