Alright I've been having a hell of a time trying to find a simple design for a post based wood crane. It's not going to be handling heavy loads, it's to help lift me groceries up my rather steep porch cause I'm lazy. I had some work done and had the gents attach a post. Now I've salvaged the painted post to the right of it for potential reuse. I plan on getting a cheap winch and then mounting it either on the unpainted post or the painted which I plan to make the boom. I had planned on using a swivel base, but I was rethinking and they don't do well with the sheer that the design would cause. So do any of you old bones know if what I can use to do this? I'm not deadset on using the painted post.

Note that the base is only bolted to the rail so this crane cannot accommodate much of a load and it isn't going to be used for that. The winch will be hand powered
