I'm working on my Master Builder Structures NMRA AP. I need two scratch built structures to finish it up. Linda (my wife) pointed out that I need a couple of bridges on the RMP, which is an Fn3 (1:20.3) garden layout, so why not build some?

Last weekend I built a small wood bridge in HO from 1:1 scale plans - just cut the wood to length, as shown on the plan and glue together. I could scale those plans up 4.29 times (87.1 / 20.3). However, I'm looking to see if you MRH folks have some already together?

Another blog post - this detailing my weekend's efforts in updating a brass steamer to DCC and adding my first 603 LED in the headlight.  And, some discoveries in Mancos CO.

I've spent the last two days riding Amtrak #11 from Seattle, WA to Southern California, CA.  And, of course, my face was glued to the window most of the time; camera and notepad in hands.

In central Oregon I spotted the perfect prototype for a drawbridge to fit a non-industrial or rural setting.  I would love to build it, even though it won't fit my layout.  So, I'm hoping that someone on this forum might have some detailed info on it.  

NOTE: I had lost the pictures when doing a web site rebuild. Just found them today (12/22/13) while looking for some other pictures on a thumb drive.

John,

I found the round-tuit button this afternoon. Here are the Atheran F7 shells. One was made into an F3A before commercial models were available. This was Atherans second up grade. The trucks were much improved on these models. Anyway here are the prototype engines.
