If you don't want to have this problem with the last connection, the other option is to use "structural pipe fittings" that clamp onto the pipe instead of using threads.

Pay very close attention to the attic structure and how this hoist is attached up there. A minimal attic truss with only 2x4 cross members on the lower joists is not up for this. I'm not happy with it grabbing only 2 joists. (tell me you didn't just use drywall anchors? Drywall has 0 strength). I'd be happier to see it grabbing 4 joists. I'm very ...

The wood should be fine. Like the others have said, there are other concerns. Is the ceiling attach strong enough? The safety margin on the hoist is marginal. I would like 5X. Calculation for the 2 x 8 on top. The deflection is not acceptable for building construction, but OK for what you are doing.

wood table pic attached if u are going to use 2x8 in the lifting orientation per your pic, then you're doing it perp. to the grain and you are not taking advantage of it's strength... which is ok you can just stack 2x8's two, three, or four thick to meet your strength needs. Not ideal obviously. the smarter thing to do would be to use a lifting strap to ...

This will most likely work if the body is as light as you say, but that seems like an optimistic estimate. When you start to lift, the board should tell you if it's going to be ok. By the book, this isn't strictly "safe", but I don't have a problem with self-engineered solutions. The one thing you have to remember is to treat the lifted object as if it ...

We don’t design for what’s normal. We design for the unusual. Just because you don’t have wind storms too often, doesn’t mean that you shouldn’t take precautions for high winds. Structural shear walls are usually at the exterior (perimeter) of the house. However, perimeter shear walls can only resist a certain amount. If the house is more than 3:1 length ...
