During my recent chicken coop project I realized how poorly I had stocked my basic building materials. When the first set of 2x4s were being put together, all I had was 8 penny nails. 8 penny might be fine for use in nail guns, but when you are using a hammer, 10 penny are much better. When the first walls were stood up, the nails were too short to hold the boards together. It was rather embarrassing when the wall fell apart as my wife and I were getting ready to put them together.
When the chicken coop project kicked off I quickly realized that I did not have the screws or nails that I needed.
the skil saw blade was dull,
my good tape measure was at the camp, so I had to use my wifes semi-pink tape measure,
my good framing square the tri-squre are at the camp, so I had to use an old rusted steel framing square.
The skil saw and the drill are fairly new so they worked well.
Another thing I realized is how messy and disorganized things can get. My shed is in a mess, the shelf system I am using is in disarray, the things I did not need were in the way and the things I needed were difficult to get to.
Due to my experience with building the chicken coop, I decided to clean the shed out (and keep it clean), and to also stock up on simple stuff like screws and nails.
