Cool. How a video to show it all in action?
You bet, Bruce. That’ll come after the programming. Thanks!

John, with projects like this, where my knowledge is slim and the outcome is questionable, keeping the bench clean is how I try to keep the project happy. It’s something controllable… (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-laughing.gif)

Same here John.
Hello Cliff,
how are you sir? Just wanted to know what software are you using to design and render your model structure I have been really curiou? Are you using Autocad or Autocad civil 3? It also looka like Autodesk Revit. Let me know please your one real talentled guy you really know your stuff sir!! How much would you charge to built something like that exactly the same?

Hi Tony, thanks for your kind remarks! I don’t know how much I’d charge though, I’ve been hacking away at this for almost 15 months, and am pretty tired of it, haha! But thanks for the compliment! (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-laughing.gif)
For 3D modeling I use Solidworks, because that’s what I use at work and have used that license. It ain’t cheap. But I’ve heard great things about Designspark and Autodesk Fusion 360, both of which are free! For pattern making on the laser, schematics, and all that 2D stuff, I use an old version of AutoCAD (2012). I’ve been using Acad since 1987; old ways die hard… (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-foot-in-mouth.gif)
Thanks again,

Hi Cliff,
hello again cliff as per the design programa i am curren using AUTOCAD CIVIL 3D at my job and I have use solid works before and it is really impressive specially for modeling mechanical parts. Which laser machine are you using to cut the 3D patterns if you don’t mind me asking sir? I really would like to know because I would like to give it a try and design something like that in the future but I need to invest in a 3D laser printe for the house. I have the program but just would like to know what laser printer you are using to cut all of the plastic and wood parts any recommendactions that you would like to share sir and also any preferences on a specific one?
Thanks,
Tony
Hello Cliff,
I forgot to ask you do you know where I can get a hold of a template or bends for making the trestles any suggestion? Or would you be willing to manufacture something like exact what you posted on one of the pictures before and sell one to me? I been looking arround the websitea bit can’t seem to find any.
Thanks,
Tony
Tony, thanks, and no need to call me sir, haha! (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-laughing.gif)
We’re talking about two things, both of which are important: 3D printing, and 2D cutting. My advice is, and maybe you’re saying this already, go first with the 2D laser cutting. That’s what I mainly use. Volume-wise, for this model, maybe 99% of the material was laser-cut, 1% was 3D printed.
So thanks for asking about the lasering. I posted the long story of my journey, which began only 20 months ago, in this thread:
Then came my first test-case building, and and then the main build threads of this mine, starting with this one:

Hope that helps,

Hello Cliff,
yes your right I totally forgot that 2d cutting and 3d laser printer are two different things and two different printers involve. I am mainly want to focus On the 2D cutting aspect of it and I did see the pictures of the 2d laser Cutter and would you be happy to tell me how much you got it for and where you got it from? I definitely need to get me one of these laser 2d cutters for my future projects.

I agree! I got mine from Ebay; there are many sellers. I’d recommend the 50 watt ones, but there are much cheaper ones at 40 watts.

Good luck!
Last Monday I worked on the foundation, and decided to use concrete. I didn’t want to mess with forms around the perimeter, but use the template itself. The template was the right shape, with its underside representing the top of the foundation. So all that was needed was to cut some pouring holes and then do final leveling.
Then I mixed and poured 3 bags of concrete, being careful not to budge or raise the template, while stuffing the 'crete around its underside.
That all went pretty quickly. Friday afternoon I removed the template. Pretty ugly, but the objectives here were to stabilize the rocks, fill most of the void, and create ridges for screeding.
All I needed to do then was mix up a bag of mortar, plop it on and screed it smooth. I came back a couple times for final troweling.
I started programming yesterday, and so far so good. Hope to finish that today, we’ll see.

Wow Cliff, For get traveling to your place to see the railroad, one could just come to see the mine in action! I assume you ascertained the height of you new pad was correct by placing a level on the long arm of your template? Keep up the fantastic work, it’s very effectively forcing me out of my brief arm chair retirement while we recovered from our move.
We’re not worthy!

Hi Randy, great to hear from ya, and thanks for the kind words! I’m glad you’re all moved, and hope you’re having a blast at the new RR job!
The audio recording this morning went better than I’d expected. Took a while to figure out how to record two audio files on my phone (my computer speaker is junk), transfer them to my PC, convert M4A to MP3, transfer to micro SD card, and name properly so the sound card would play them. But all worked fine, which was a relief.
Final programming went well, mainly working out the timing. Then came a bit of figure work and buttoning up the wiring.
Here’s the animation.
Yee haw! A little problem with the shed light though, rrrr… I’m ignoring that for the moment.
Jim R., you asked about the code, and I’d said it wasn’t needed. But, because I needed a couple queue inputs (from the reed switch, every time the tram passes the shed), that forced me into coding a script, vs. the simple method. So FWIW, here’s the script. It’s a very rudimentary language, with the parameters being issued before the operators. That’s because you can’t store any variables; it only works with a stack of integers. OK, geeking out here, I’ll shut up… Oh, and “#” precedes comments.

Very fun animation Cliff! Nicely done…
And thanks for sharing the script. Your use of "sub"s makes it super readable. Looks kind of reverse-polish-y:
Thanks Jim! And yeah, isn’t it bass-ackwards?!
Trying to make the video work… Can someone point me to the instructions again? I’ve tried a couple ways but can’t get it working.
