This instructable covers the significant steps involved in taking the siding hammer idea from concept to patent. Vinyl siding expands and contracts with temperature changes. If vinyl siding is nailed too tightly the siding gets trapped and is unable to move properly - this causes unsightly buckling. The siding hammer helps to keep the nails from being driven too tightly.
Step 1: Some Drawings From the Patent
The drawings give a pretty good idea of how a basic idea can be expanded to different variations that end up having the same function. I included in the patent most all variations that I thought of at the time. Some of the alternative designs are more practical than others.
Step 2: Video of Prototype Development and Testing
The video points out why the siding hammer is needed and some of the steps I took to get from concept to the patent stage.
