Reply to comment by fardough in Fourth Circuit: Individuals Have a First Amendment Right to Livestream Their Own Traffic Stops by mepper

Impossible due to the SCROTUS rulings on qualified immunity which doesn't even exist in the underlying legislation. You can't get busted as a cop for screwing over a citizen unless there's case law in that court circuit specifically declaring what the cops did before is not allowed. But you can't get that ruling made until another ruling is made before saying the same thing already. So you can never get a ruling at all.

Reply to Setting 4x4 posts in footer or on top, ‘joists’ on top of 4x4 with a bracket or through bolted to the side? by Bigfornoreas0n

Posts have better shear resistance set in concrete or with shear resistant brackets. 1 ton is quite a lot of concentrated point load in a hoist system. It's very important to ensure that the brackets connecting that to the lumber distribute the load properly and are arranged with through bolting instead of lag bolting and without an excess amount of wood drilled out to provide adequate load transfer. In addition to that the right amount of wood cross joists and beams or truss system to transfer that load is very important.

Lifting heavy things overhead is a life safety application so it would be very wise to collaborate with a PE in your area to get stamped drawings calculated with an appropriate safety factor for variability and glitches that happen in lumber based construction because a failure could cause serious negative consequences for life or property.

4x4 posts won't really offer the best shear resistance because they will tend to deflect easily under heavy compression. It would be wise to figure out how to cross brace all the posts to their neighbors to increase stiffness.

Reply to What is the max joist span for a deck with deck blocks? by OrangeYouGlad100

Make sure you're considering all of the factors in designing this and see if you can get some sort of plan review from somebody with experience.

For example, if you frame the deck with 2x6 only, you will generally not be able to attach the safety railings strongly enough to meet the 200 pound midpoint all directions force resistance requirement according to the testing done by some reputable engineering journals.

You also have to think about snow loads, springiness from using minimum code spacings and spannings, how to attach it to the house securely, type of lumber used on the various components, strength of the staircases (if any), etc.
