Animating Xmas Parade Float Answered
Below are some pics of the Xmas parade float that a few of the other dads and I put together for last year's town Xmas parade. We are planning on keeping the same theme this year but wanted to upgrade a bit. Our goal is to automate the reindeer to give them some linear action that will give them the appearance of flying.
When reviewing the pics, please note that the frame that the reindeer are attached to will be completely rebuilt. I was thinking of a frame with a double 2x3 side. Where one of the 2x's will have a channel routed out in it and the other one with the reindeers attached will then be able to slide back and forth by it.
Another note is that Rudolph will not move.
I have included some rough sketches of my initial thoughts using a motor and a cam. My problem is in finding the right motor for the job. I would need a high torque, low rpm (about 20) motor to do the job and I can't seem to find one. I have thought of using a mixing drill and a speed controller, but the mixing drill has an rpm from 0 - 550 and I am not sure the speed control will be able to slow it just 20 and even if it does, I am not sure there will be enough torque at that reduced rpm.
I am certainly open to other suggestions. Thanks in advance for any thoughts or comment you may have.
