I wanted a watch case for up to four watches to take on an upcoming vacation. I needed it to be strong, weather proof, dust proof and lockable. Here's what I did (thanks to all the inspiration from all you WUSes! ).
The Invicta will be staying home, but was used as a placeholder. I've seen people use toothpicks to mark their cuts, but I didn't have any handy, so, necessity being the mother and all that, the paperclips worked just fine.
At first I used this knife, but it wasn't very sharp after 3.5 years of constant use.
This kitchen knife worked way better...
I ended up using 3x6 blocks for each watch, with 3 blocks on every side against the case, and 4 blocks between each of the watches. It seemed to work out alright.
Again, from inspiration from this awesome site, I went to a big-box store and bought some 1" self sealing pipe insulation (~$7 for 6', I wish I could have just gotten a foot or two, but oh well). I then stuffed it with some of the pick-n-pluck foam.
One thing I noticed was that the foam on the bottom of the case way WAY thinner than the foam on the top, so, since I had so much extra pipe insulation, I cut a piece the same size and stuck it down in there instead.
It didn't appreciably push up the rest of the foam, and I think it will provide a lot better protection against scratches on the clasps of the watches.
And the finished product!
Thanks for all those who came before me (so to speak) for the inspiration and knowledge!
