hydrolics

Hi all,

This is going to sound silly, but I am building a car bed for my 13 year old son and I am wondering if I can safely put hydrolics on the bed. My brother said something about "leaking fluid"--I definately don't want that. I have an idea of what I want to accomplish, but I don't know how to go about it. Can you tell me the best way to achieve the "hydrolic car bed" or give me suggestions of a simpler way to get the same or similar results? Obviously, I know nothing about cars, but I'm open to any suggestions. Thanks

to run hydraulics you need an electric pump, these require alot of power. If you did it well it wouldn't leak. I would suggest using electric servo motors though, I would never want a hydraulic system in a bedroom and its really hard to build your first hydraulic system.

How about air? If it leaks its not a mess, and air compressors for home use are a dime a dozen. Put an air compressor in your garage, run a hard line to the bedroom, and put some junkyard truck airbags under the bed. Big lines, big valves, your kid will have instant "catapult" capability at will :)
