    Post Linear Actuator

    This doesn't actually apply to mp3 players but im gonna ask here anyways. I'm trying to put my sub box on a track so than it can slide into my car when the back seat is down. (Giving me accses to the spare tire in the trunk. Ive got that part all worked out. But I want to motorize it. The only linear actuators I could find to do this cost around 300-400 bucks...more than i have to spend. So does anybody know of a way to get one cheaper or maybe an alternative?

    Catlas

    P.S. I'm looking for 12 or more inches of travel.

    I've heard that you can use a power antenna motor. I think they are pretty cheap new, but you could probably canibalize one from a wrecked car in a junkyard for next to nothing.

    They only problem I see is if your box is heavy, the power antenna motor won't be powerful enough to move it.

    Cool

    As long as the box is on rails, the power antenna will be able to move it. Those things are pretty beefy.

    Also, look into a power windows regulator. They are available cheaply at any wreckers, and have enough power to take off your finger.

    You may be able to find a worm drive a lot cheaper than that too. Although it would be slower than an actuator.

    Not sure if you ever found something that would work for this but one of these might do the trick nicely:

    i agree with aaron. get yourself a nice ball bearing drawer slider (they are available in pairs or one for underneath, get a full extension slider) and with any window motor you have a great motorized drawer.

    to make sure you don't pull the drawer out too much, install a small switch somewhere at the end of your drawer travel to cut the power. then do the same to bring it back in.
    i dont remember what you call the switch. it has a small metal piece over the button which makes contact when the drawer is all the way out. you'll need a double pole double throw switch to control the drawer reversing the opposite sides for the motor in and out directions. the motor is wired to the center poles.

    power antenna moving 50+ pounds? I doubt that will work effectively/reliably

    You need to remove the antenna, and simply use the retracter mechanism. It's usually a long plastic gear that is wound around another....It's quite strong, but don't abuse it.

    As someone who works extensively with actuators, I will once again say, that this will not work effectively
