RE: tree stands?
I have five fixed position stands and one ladder stand and they are all used throughout the course of a season. In the past we built wooden permanent stands that really are not permanent. We also built some wooden hang on stands from instructions out of a magazine. I wouldn't recommend building your own stands in general unless you are a combination mechanical engineer and fabricator. Stand manufacturers have done the research and have the experience as well as the lightweight materials that make the stand much easier to hang.
