Comments Regarding the kind of wood that is used to make the dummy. Please recommend a wood type that is most suitable for training as well as durable for many years. Can you also comment on whether the stands are life-time guaranty as well, and if the stand can be backed into a wall. Thank you for your time on answering these questions for me. The choice of wood is almost totally a personal one.
Hickory is very tough.
Tool handles are made from hickory because of its outstanding performance. The handles will break after years of weathering and overuse not because you are beating on it but because of the design and its particular usage. Now imagine hickory the size of a dummy. It will never break under the minimal stress dummy training puts on it. But so wood most other woods because dummy training doesn't really stress the body much.
