  • Custom HO Guard Rails

    The recent posts by Fastlap about his F.I.R. Track guard rails ( F.I.R track reconstruction page 2 ) has inspired me to continue with guard rails for my track. I've been thinking of trying something new and now have worked it out. To me RCA 18ga. 2 conductor speaker wire looked enough like armco rails that it might just work. I used "Shoe Fix Glue" to hold the Evergreen posts to the wire as super glue or epoxy really didn't hold. Also found out that enamel paint never quite dried and stayed sticky and acrylic just didn't stick well so I bought some lacquer spray paint and it works great and dries in maybe 10 to 15 minutes. Overall I'm really pleased with the results of how this turned out.

    Here are the pictures.

    This is the jig I made to construct 2 or 3 tier rails. The file is used as a weight to hold the posts to the rails as the glue dries for a few minutes.

    Set in place.

    RCA 18/2 Speaker Wire (I bought 100' rolls but it's available in several lengths.) Home improvement stores is one place to find it.

    The glue that works - really amazing grip and easy to use. It's made to hold soles of shoes to the uppers so it dries really strongly. You can find it on Amazon or eBay.

    So, that is what I've started. I"ve only got 50' or more to do but I think these will add a lot to the realism of my track.

    Looks good. Now you need some poles with loudspeakers on them around the track. I mean, you have the speaker wire laid and all……

      Not trying to steal anybody's thunder here, but I thought folks might be interested in my experiments with 3D printing Armco guard rail.

      I was trying to develop guard rail for my new, routed 1/32nd scale track. I tried to simulate the 3-high construction commonly used on Grand Prix tracks. I came close, but due to the limitations of the printing process I was not able to create the small vertical gaps between the three elements of the railing.

      For those interested in the printing process, I used a gray grade of PLA, printed on a Creality Ender 3 Pro. I printed without a raft or brim, using Elmer's School Glue as an adhesive. In all of my trials I printed the railing in a circle or spiral, attempting to create the maximum length of railing in a single piece. I figured I could open up the curve of the railing to make the radius I needed, and probably straight sections as well. For inside-corner railings I figured I could reverse the print, so the railing was convex instead of concave.

      My first attempt included posts printed integral to the railing, with holes down the middle for mounting screws. It was successful, but I was not happy with the scale of the mounting posts.


      So I revised my model, making the posts smaller and tried again.


      Eh, okay, but printing enough guard rail for my track would take, like, maybe a week. So I tried printing the railing in a spiral instead of a circle, and this time without mounting posts, with the idea they could be printed separately and then assembled to the railing.

      This was much more to my liking. I found I could print over 7 feet 4 inches of railing in a single job. It took over 15 hours to print, but no problem. I could just let it run overnight. Still a ton of printing, but much less trouble overall.

      I should point out I was able to create end tapers similar to those used on the real Armco barriers. If you look hard you can see them in some of the photos here.

      And that is where I left it. I decided to use clear Lexan as my crash barriers. Less of a visual obstruction and easier to install. Not at all authentic from a modeling standpoint but great for racing.

      To better illustrate the length of the spiral-printed railing I slipped it into a slot of my HO oval track. That's quite a bit of railing to fit on a 3D printer build plate.

      I tried to attach the STL files for the spiral railing, but I couldn't get it to work. So if anyone would like a copy of those files -- free fer nuthin' -- just send me an email at '' and I'll try to send you copies. That includes both the concave spiral and the convex spiral.
