    I was thinking about putting a train draw bridge on my layout. I want one that pivots at on end sending the other end up or down. Has anyone ever tried this or know where I can look at one?

    Yeah, like that, is it best to buy one or could i make one cheaper?

    Bascule Bridge

    Bascule, or other form of moveable bridges, require some
    experience , and skill with both making and finding already manufactured components; as well as with fitting it into the layout. They are not a beginning scratch builder's project, unless you bring the skills from another area (e.g.woodenship model building, cabinet making, model engineering,etc.).

    The Walthers' kit does not go together easily. To produce
    a reliably operating model requires re├źngineering the mechanism, which generally puts it out of the skill range
    of the novice modeller. However, carefully assembling it
    as a static model can be done. So if you want scenery as opposed to a working Scherzer lift bridge go for it!
    As such, it provides the components that would take work
    to scratch up, so it would be easier than starting there.
    Please understand, even as a static model, it will require
    you to" file and fit" the kit, in manners not explained in the
    instructions (unless they have revised them lately).
    Good-Luck, Peter :)

    I have a lot of experience in wood working, small engines, and in college for an engineering degree hopefully. I have already thought of different ways, i was just wondering what would be the most cost effective, i am on a really tight budget for this.

    Build your own. Study bridges as much as you can and learn why different bridges are placed at different locations. If you have access to AutoCAD, you can print your own drawings on sheet styrene and cut the patterns out. Or you could print on paper and laminate it to cardstock. There are many ways to do it and do it cheaply. With anything that moves, precise measurements and cuts are required, so take your time and do it right. Good Luck!

    Nick, here is my solution to this problem. It IS a project, one that I probably would not want to do again. It has been in place for about 8 years, used almost every day, and has required very little in the way of maintenance or repairs.
    The secret to one of these things is to first determine exactly how it functions by studying pictures and drawings, if you can find them. Then you probably should make a scale drawing of the bridge you want to build. Next step is to purchase the materials (I used Plastruct ABS, but now they have finer-scale Styrene I-Beams, Angles,Tees, etc. Then it's a matter of cutting and fitting. One thing that must be exactly correct is that all pivot points must be in the same plane and aligned exactly. I hate to keep using the same word over and over, but EXACTLY is the key word. I didn't necessarily get it right the first time, or the third time, but eventually, it worked. Perserverance is another key word, come to think of it!
    But when you finish it, you'll have built something very few others have done.
    And I think it's something to be proud of!
