this 1 just so happens to rip your jaw apart, but its pretty complicated 2 make. just be creative. I had a saw room last year and you just have to give the room some dim lighting, and a bunch of blood stains.
you could also use power tools safely. ex: power drill with no bit, jigsaw with no blade. Good Luck on whatever you decide to do.
I thought of all the power tools. I grabbed an old 70's office chair, I have no other means to get a real chair, the office chair would be better for the dentist then the patient unless I turn my old picnic bench into a layed out flat bed/chair. Do you think I can grab a old rusty sink off someone boulevard during garbage week?
