| For the Mausoleum scene, I originally intended the doors to be closed, then when the motion detector is triggered they would slowly open at the same time. Since I was using 120Vac motors, there was some concern regarding the timing of the doors opening and closing properly. Since I made a flange on one door edge to cover the seam between the doors as actual doors have; the door without the flange had to open first, then the door with the flange would need to close first. Otherwise there was a chance that the doors would bind and get damaged. | ||
| Since time was short, rather then work
thru that problem, I decided to motorize only the door with the flange
and the other door would be left open. I used the base of an
oscillating heater and added a couple of 1" wide aluminum bars for
the linkage. I made a small l-shaped bracket from scrap aluminum to
connect the bars to the door.
A wide piece of 1/4" thick luan is securely glued to the bottom of the foam door with Liquid Nails construction adhesive for connection to the linkage. I used some scrap pieces of wood as stops for the motor. When the linkage hits either stop it automatically reverses direction. Since this is how fans/heaters normally oscillate, I just changed the angle at which it reverses to suite my needs. With the angle of the linkage to the door is about 100° and the angle of rotation for the motor is about 80°. |
