Resin printed 90 lb & 115/131 lb adjustable rail braces for code 40 rail /1:160th/possibly 1:120th


90lb rail brace. .043″X.043″X.028″

Rail braces are one of the harder patterns to cast in quantity. In machinable wax they take about 25 minutes of cut time per brace. They’re nice and accurate, especially for 1:160th, but they are a hard casting to pull and I wouldn’t want to make them for others. When  I first started in on my resin printer build they were at the top of the list to print and be done with. The 90lb ones will be available soon. I’ve only just started making and testing the adjustable braces.


Had an FEP failure while printing these adjustable 131 lb braces on the first go around.  Only 1/2 of the first plate is saleable but luckily I can use the rest.  Judging by the artifacts the resin was likely contaminated by an earlier print. Still learning how to do these full plate prints. You can really here them pop when the FEP releases.

It’s worth noting that these are fairly small autonomous parts that are easy to lose and sacrifice some ease of use  for the sake of resolution and repeatability. The easiest way to get around this would be to print them with to a tie base. That way, anyone could use them regardless of dexterity.

Some pros and cons for both systems:

Free range rail brace



augments existing Code 40 empires

More flexible


Very small part that needs de-spruing.

Integrated switch ties and rail braces


Ease of use. One piece with all of the static details incorporated.

No critical de-spruing.


More costly (consumables/print time/repeatability).

Long term gauging essential for to-scale applications is more difficult to attain without adding reliable gauging materials. PCB being one example.

Different artwork for every flangeway/switch length/tide chart.


That said,  I do have switch ties ready to print for my display table so I will probably test with them as well.

  1. Very nice, Andrew! You know that you can get away with very few switch angles if you decide to print integral ties. I believe (from memory) that they are mostly all 13’ switches for the typical model size switches.

    Thinking of bringing some to the Railway Modellers’ Meet?

    • Yeah, the problem at this point in time is that I don’t use any of those common model railroad switch lengths. That’s a me-problem that I might look into fixing – just not sure at this point. N scale is still very much the wild west so far as tighter flangeways go. FS -160 might be viable. I need to dust off the specs and see what changes are necessary.
