It is Punch. It helps give you an idea of what the finished product will be.
There's no patent here:) I just needed a way to lift my trusses. I had a jeep with a winch and I had a long ladder so I built it to do the work. It worked great.
My Old Garage
These are some pictures of the garage I built at my old house. It was 30 x 40 with a 12 foot ceiling. I really wish I didn't move. I had my heart and soul in it. It's not near as nice as some on here but it was a first and a great learning experience.
