This is one of several Instructables that cover the building of a 1:160 (N) Scale Model of a Bascule Style Railroad Draw Bridge. This Instructable addresses printing and assembly of the drawbridge lift mechanism and it's integration with the bridge component. There are two other Instructables with one addressing the printing and assembly of the bridge and the other covering the electronics. There are also two articles on my blog that are worth reviewing (first article and second article).

The irony of my designing this bridge is my total lack of an N-Scale Model Railroad Layout! That has not stopped me from enjoying the project though and hope to see others build the bridge and put it to use. One person is doing so and has shared this gallery of photographs from his build. They are all worth a look but the ones that are most salient will be linked into the appropriate page of this Instructable.

Step 1: Assemble the Needed Tools

In no particular order relative to the photograph here are the tools that you will be needing:

  1. Super glue, and optionally, some accelerant. I find the latter to be really handy stuff though I know that it detracts from bond strength. Your call!
  2. Small pair of needle nose pliers.
  3. Small pair of wire clippers.
  4. Philips and regular screw drivers.
  5. Small detail files, at a minimum a flat one and a round one (maybe some fine sand paper as well).
  6. Tweezers.
  7. Torch style lighter (or kitchen torch or shop torch or soldering iron with blade tip though may be too hot)
  8. Some kind of tool that can be heated with the above and then used to melt the end of a retaining pin.
  9. High temperature oil to be used with the above to help plastic to not adhere.
  10. Craft knife, known to some as an Xacto Knife
Brilliant! I love your ingenuity! I am an O gauge railroading enthusiast and would welcome your thoughts on applying these principles to a 1:48 model. Thank you and once again great work!
Thanks for the thumbs up...it was a fun project. O gauge, however, is big! Way bigger than possible for anything but a special purpose printer! Technically not an issue just one of logistics. The other problem is one of detail. My models would look crap scaled up as I have not designed in the kind of detail you would expect as they would not print at N-Scale sizes.
