Dad's contraption to raise the drawbridge...


You can't just leave it at that!!! I gotta see some pics of the drawbridge in action. Up, down, how it works. Details and lots of pics.

Thanks,
Eddie

Unfortunately, I don't have any more drawbridge pictures with me. But I'll be sure to take some when I go home again. Either that or get some from the folks. They practically live out there.

Now I could tell you basically how it works. First off, there's a garage door opener mounted under the house that raises and lowers the bridge. So an elaborate system of pulleys was necessary to achieve the leverage. And the springs are there to assist with the initial upward motion. But the contraption only raises the bridge to a 45 degree angle. So it's mainly there to keep critters (i.e., ants, mice, racoons, bears) off and not mischevious people.

Cheers,
SC
