Drawbridge with Chains

Post by ezehogan »

I have had enough of goofing off. Modifying existing sets does not give me any pleasure anymore. Its time I build a larger MOC castle.

I have come up with some rough sketches and ideas for this castle I hope to create. At the present time, I don't even have anywhere close to the amount of gray bricks that I will need, but this will change over time. If I just keep plugging away with a few sets here and there, I feel that I could be ready to go within a few months (especially if my stock investment works out, although I probably shouldn't have all my eggs in one basket ;-).

In the meantime, I thought I would mine for ideas I could incorporate into the castle I want to build, perhaps even make an Ldraw version so I can get a feel for things and be prepared when the time is finally here.

One of the things I hope to incorporate is a drawbridge using chain and not string. String is easy to use, but I don't think it looks quite right on the larger castles. However, I am not quite sure as how to use the chain pieces for a drawbridge, as I have never owned a set using these pieces. I wanted to know if anybody could share their methods with me. I'm sure it is more simple than I am making it out to be, but I still would like to know for peace of mind.

Hello!


It's possibly possible (huahua) to make a drawbridge entirely with chains. However, I use a combination of chains and string:

String sinply is better to handle with a reel winch than those chains.

The main problems I found with trying to use chain is its simply not long enough nor flexible enough to be wound around a drum.

The solution I came up with was to use a combination of beam and chain (very prototypical) to lift the drawbridge.

Two sets of chains are used to lift the drawbridge, the first set start the lift, while the second set complete it, bringing it tight to the wall

The "inside" ends of the beams are linked to pneumatic cylinders in the cellar, operated by an externally accessible switch, although a winch could be used.
