A simple mechanism drawing. This is a single cylinder casket popper.
This is a ceiling swinger prop. 1 cylinder for each arm and another cylinder to operate the head back and forth.
This is an animatronic coat rack. A cylinder for each arm and one for the head.
Giant (14' tall) prop erector in it's down position.
And in it's up position. The cylinders can be operated in all my models so that I can check exact movements and make sure there are no interferences.
This is the back of a one off custom prop I built in 2008. A cylinder for the spine turn, 1 for each shoulder and then 1 for each elbow. As you can see I use pillow block bearings on almost every movement of every prop.
An animatronic plant monster I am building. This is it in it's up position with arms open. This design uses over 20 bearings, including a linear bearing for the lower rear slide.
Same thing, but from the side. There is a cylinder to operate the scissor movement up, one to operate the arms opening, then 3 to operate the head up/down, left/right, and jaw.
Shown in it's closed and collapses position.
From below.
An animatronic sleeping bag kicker. This is to show my methods of cylinder bracket attachment and bearing use. I bolt every cylinder bracket to the frame. I never weld them in place. That way the forces can not fatigue the welds on the brackets, which are the most likely to break.
A small scissor mechanism I designed. It uses a single cylinder and linear bearing to achieve the scissor action.
A torture table prop I built. Once again to show cylinder attachements and bearing use.
This is a zombie chaser I built. The body mechanism is driven down the length of the table on a linear bearing and driven by a cable cylinder. There are cylinders for each arm and 1 for the spine/waist movement.
Showing the cable cylinder and linear bearing. I calculate load ratings and life expectancy on all bearings and make sure they can handle well over the loads they will see, and make sure they will last for years with little maintenance.
Same mechanism showing the lower bearing and spine assembly, and my use of a cable carrier for the bodies airlines, so that they can not be damaged by the forward and backward movement along the table.
An overall view of the model.
Below is a machine I did at my day job. I did a lot of the engineering and most of the assembly and manufacturing.

ReplyDeleteGreat. Why don't you start a prop company while your at it. :)
