Peter, it looks terrific and the utility/storage is an inspiration.
May I ask, what catches do you use on the doors? Are they strong enough to stay closed in travel?
I thought I might need to get those tension catches or whatever they are called, when I get to the doors on my "work in progress" but I prefer the simpler knobs like you have.
I'm experimenting with something new for my catches. Instead of using mechanical catches of any type I'm using high-power neodynium magnets. I gave these a test run on my upper cabinets, and have been very pleased, so now I'm installing them everywhere.
The concept is simple. I use ring magnets with tapered counter-sink holes in them from K&M Magnets
(ordered in a 10 pair-set; it was cheaper to get 20 magnets that way) on the door side matched to a simple nut, screw and trim piece on the fiberglass cabinet. Seems to hold really well.
These little "N-42" magnets require 13 pounds (6kg) of pull to separate them from an iron surface, and that seems to be enough for most of my doors. I'm using a pair of them (top and bottom) on my pots-n-pans cabinet, which has heavier stuff inside, but may discover I have to move to the next stronger magnets with a pulling force (22lbs, 10kg)
. If worst comes to worst, I can pair the magnets up, put a pair on the cabinet as well as on the door, which will again double the amount of pull required to open the door.
Two words of warning about these stronger magnets: First, the stronger the magnets are, the harder it is to separate them. I had a pair of these 1" diameter by 1/8" thick magnets that generate 80-lbs of force each
. Separate them by even 1/8" and they're much easier to get apart, but when a pair come into direct contact it takes about 160lbs of force to pull them apart; thats about what a man who trains in the weights room once or twice a week does on bench press. The point is you can get magnets that are so strong it becomes a chore to open a door. I'd stick with the magnets I listed above and not go any stronger.
My second warning is the metal in these magnets is kind of brittle, and the higher the "N" number (a measure of the magnet's strength per gram), the more brittle the metal alloy becomes. How brittle? That pair of "N-50" 80lb magnets I mentioned? I was playing with them, making one magnet levitate over the other when one of the magnets flipped over and the two of them came together with such force that they both shattered explosively, sending glass-sharp shards of magnet around the room. At least the mess was easy to clean up: I just waved one of the larger shards around over the table and floor and all the little magnet bits jumped right to it, but even after cleaning up the room the mess wasn't quite dealt with. When my son collected the garbage from all the rooms of the house on garbage night and took it out to the can in the garage, the cluster of magnet shards tore a hole through the bottom of the plastic garbage bag as my son passed by Lynne's car. I had to remove the larger pieces from the hood using a pair of pliers.
(Once the larger bits were collected in one spot, the smaller bits happily popped off the hood to join the mother ship.)
The smaller "N-42" magnets I'm advocating for door catches aren't so strong or so brittle that they'll shatter.
