Suggestions for the joint are at the end of the post, so skip there if you do not want to read my ranting.
I see no problem with calling a prop a lyching, hanging, torture room, crypt, or any other term. the point is to make the scare work. If the name helps to set the tone, all the better.
My offense is the Empress bringing in that she is African American and that they have some special place to be offended by the term. Lynchings have been perpetrated all all types of people against all types of people, and no one group has any right or need to be more offended than any other.
In just the recent past, we have had an example of lynching in Texas where white people dragged an African American behind a pickup truck until dead. We also have an example where African Americans in Los Angeles dragged a white person out of his truck and beat him almost to death. In both cases, the victim did nothing at all to the perpetrators, they just happened to be the victim of choice. The key word here is choice. Both events were driven by what is called racism.
NOTE: Humans are one, repeat ONE, race. There is no such thing as a white, black, red, yellow, green, or whatever race.
Anyone that believes in "racism" must believe that there are in fact differences that are based in the color of someone's skin. For myself, I believe everyone is equal.
People DO hate people that have different skin colors, just as they hate people of the same color as themselves but from a different country or tribe or belief system. Most of this kind of hatred is inherited. A child learns it from their parents, who learned it from theirs. The original cause is usually lost in the past, but in many instances can be traced to a dispute over land and/or resources; a "This is mine and I do not want anyone trying to move in and take it over" mentality.
The few people that I have met in my life that admitted to being 'racist' could not explain why they were other than to say something like "They deserve what they get", or "Look what them people did in the past".
But, I digress (digrid? digrode???)
- - - THE SUGGESTED BUILD PROCEDURES START HERE - - -
A good way to make the joint would be as follows:
Use the same diameter PVC for the upper and lower parts. Then, get a connecting piece that fits over the ends. Cut the top half of the connector so that you can ALMOST push the top piece straight in (like laying a hotdog into a bun). Straighten the edges flat (soak the connecter in boiling water for a few minutes to soften it.) Then drill and insert a bolt to hold it to the top piece. NOTE: Drill and insert the bolt with the joint bent to where you want, not while straight.
This will allow the lower section to swing like an arm or leg, but not go past being straight.
For our motor-driven hanging man, we just used two pieces of wood for each leg and screwed a hinge on while they were layed end-to-end on a flat surface. This is the simplest way and it achieves the desired effect.
I hope that helps.
