Templot Plug Track Developments

Chris

Thank you and it just goes to show either modelers ignorance of how Templot works or they no little about track building

We did have a chat about whether to demonstrate a straight turnout, or a curved turnout, it was my choice to keep it simple in a format most modelers would understand, had I displayer a turnout with a negative curve, they would be stating the opposite

The thing is that firstly printing plug track using FDM printing was about 4 weeks old, COT track probably 2 to 3 weeks, plus I only had the Neptune printer for 10 days prior to the show

As those who keep track on Templot plug track know only turnouts are supported at the moment, Martin is working on obtuse crossings at the moment, but this is work in progress and relates to both Plug and COT track, not to say we are still experimenting with FDM printing of chairs

Many things in track building cause strong opinions, some still feel that joints will fail unless they are soldered !! I have spent quite a lot of time mending failed solder joints on rivet built joints, not to say the results of corrosion with steel rivets !!

I must say in the early years, I was unsure about the longevity of non soldered common crossings. There was and to a lesser extent some displeasure with Templot and apparently how difficult it is to use, which in its basic form is completely untrue.

For most now Templot is the gold standard for accurate track plans, the plug track development is an interesting project which is developing, the big news is that in the larger scales (7mm +) producing chairs has become much simpler, in that we can now FDM print chairs.

On their own (individually) FDM chairs like injection moulded chairs are fragile, and like injection moulded chairs they must be threaded carefully, the odd one may break (like injection moulded chairs) but can easily be stuck back. But like injection moulded chairs they gain their strength in numbers

The B7 turnout survived 2 days of being handled at the show intact, nothing broke !!!

Yes its only turnouts at the moment, but that goes for plug track as well.

In common with reports from many folks, I found Templot to be massively confusing and counter-intuitive when I first started playing with it - it was a Christmas present from Madame, I can’t recall which year, but maybe 2004 or 5?

Martin had noted that this was typical for those used to CAD and so I assumed it was something I had to learn to use, the way it was meant to be used. I guess you’ll not get far trying to drive a car if you’re only trained to drive a steam engine.

I’ve used it off and on in the intervening years, and wouldn’t try to make track any other way, though it seems to be a learning curve every time I come back to it. I think that’s me, not Templot!

I’d still use Peco outdoors (as drop-in replacement is easy) or for fiddle yards etc.

John, I did build an experimental length of plain track using my own resin 3DP chairs and laser cut sleepers. They were based on the dims that Martin shared with me. Works fine as might be expected.

I did intend to share the STLs on here and @adrian did set up the site to allow it but the file sizes are large and I have not managed to do so yet. I will get a round tuit….

It did however make me smile at lunch on Saturday sitting next to some chaps from another layout. There were several there who were opinioning that this new fangled printed track was only ok standard straight turnouts (B6 etc). Anything else was far too complex.

Hi Chris,

This is true for folks who expect to just switch, click a button, and there is your track.

And for them it's likely to remain true. But Templot is not intended for them and never was. There are turnout kits and other computer programs to meet their needs.

Templot is a tool for track-builders who know what they are doing. I created it originally for my own use, and I'm now happy to share it with anyone interested. But the assumption remains that you know what you are doing.

It's not quite true to say that at this experimental stage it can do only turnouts in 3D. What it can do already in 3D are REA switches in sizes A to F, straight switches in sizes 9ft, 12ft and 15ft, REA V-crossings in sizes from 1:3 to 1:20, and plain track panels with REA ordinary chairs and joint chairs.

So sure you can create turnouts, straight or curved, or on a transition curve. But using just those components you could also create say a 3D-printed tandem turnout if you arrange a design which doesn't need any half-bolted chairs (coming soon). Or a one-piece curved crossover with long timbers at the centre:

That's a 1:8 crossover in 0-MF. Notice that you also get the proper spacing blocks between the rails in the V-crossings.

Notice also the old-style cast "A" chairs. Suitable for yards and sidings. The modern slab & bracket "A" chairs are coming soon. Likewise the K-crossing chairs for diamonds and slips, and slide chairs for switch-diamonds.

But it all takes time. Templot is however now an open-source project, so any help with future developments is very welcome:

cheers,

Martin.

I have been experimenting again, I have had a goal to build a diamond crossing in plug track, initially it was to be to EM gauge and using Exactoscale obtuse crossing chairs to plug the gap. However I needed to get to grips with resin printing. Hot weather was giving me issues and when 7mm plug track let alone COT track immerging added to the fact I was migrating to 7mm scale anyway plans changed

This is the second of my experimenting, one was a challenge coming from Scaleforum but both equally relate to an overheard conversation again at Scaleforum about Templot 3D only good enough for the simplest turnouts (old school doubters?)

Well I decided to have a go at a 1-6 diamond

182.jpeg

At the moment the automated route to build a 3D diamond crossing stops in the middle as obtuse crossing chairs
However during one of our Zoom meetings Martin showed us a work around. I printed my first attempt in COT track, which was sucessful except for 4 check chairs, my work on the work around affected them

183.jpeg

Next up I printed the outer two ends

Initial thoughts is that the center brick will need to be printed using the plug track system, namely sliding the chairs on to the rails then fitting them, Initially using solid jaws (complete chairs) but it may well have to be loose jaws

Longer term the automated system will provide a less onerous building process/method. But then what is it replacing now?, soldering up 2 sub-assemblies !! To my mind especially as we have the filing jigs this method is certainly a bit less difficult

Still as I said its an experiment and I can clearly see the challenges ahead

An update on the turnout

179.jpeg

A Dapol Terrier gliding along the B7

180.jpeg

This is an old CCW whitemetal kit on a more modern brass chassis with Slaters wheels, just as the Terrier. glides along the track through the common crossing

The detail coming from the Neptune 4 printed FDM prints are superb, certainly in the main very easy to build, the cost of materials will soon repay the cost of the printer when comparing against the cost of a ready to run model, even better when compared to a kit of the same size and as for a professionally built kit. But I my opinion its the level of detail that really wins out over all other methods

Moving along with my Templot plug/COT track experiments is to test what is possible with a diamond crossing at this moment

185.jpeg

Well here is one half of a diamond crossing, the heal is in COT (chairs on timbers) track and the obtuse crossing is in plug track, the reasons for this is fitting the K (obtuse) crossing rails would be too difficult. Martin is hoping to have this formation in a selection tick box as well as the amended common crossing with glue on chairs in the next upgrade

I am now printing the chairs, and have a much better understanding on how to construct the crossing

Will there be an opportunity, for those without a printer, to purchase the plug-in track in P4.
Many thanks

Sorry about a lack of replies

The simple answer is yes, on Templot Club one of the members is willing to make available laser cut bases and resin printed chairs

Go to Templot Club and ask the question

7mm COT track has moved on, still only turnouts readily available but not a much easier build method for common crossings has been released

191.jpeg

The outside part of 3 chairs (each side)are printed separately, simply slide in the wing rails and glue on the 3 chairs

192.jpeg

A close up view (including microscopic strings) of the half chairs, simplifies track building no end.

Hi John,
I have registered on Templot Club, entered a question in the ASK field, and then came to a grinding halt!

Have you used the search facility first to see if your question has already been answered? Understandably, Martin W gets miffed if a question that he's answered many times gets asked again!

Hi,
The Ask function is just a search engine and will not result in a post. Do you see an Orange rectangle "Start new topic", you should see that if you are now a registered member. It is probably above the box showing members online.

Hope that helps.

Hi Stephen,
That's very useful, thankyou. I now have Terry's email address, so I will pm him.
Thanks again.

To all

I have found those on Templot Club extremely helpful. I have no doubt anyone who wants to explore Templot 2 & 3D programs will within reason find the assistance they require.

3D printing as far as track building has come along tremendously in the past 3 or 4 years, to a certain extent in the past 2 months at least for 7mm + modelers the game has really changed. I think for the foreseeable future progress will slow down simply as work needed in the background needs to done prior to the next milestones in all scales.

For me its a case of a series of test prints. My initial results have been far greater than I was expecting and I think I need a test track so I and perhaps others can understand the opportunities open to us all

Firstly Templot track systems are freely open to all, Templot is free to both download and use, and Templot Club constantly assists others with their hobby, without any adverts etc
Secondly the actual build process is very simple, no gauges are required or prefabricated sub assemblies
Thirdly with the use of simple to use and inexpensive filing jigs, forming the rails has been made very easy with the minimum of basic tools

You will need or have access to a modern FDM printer, there are a few simple processes to learn, which will result in a highly detailed model at a fraction of the cost of a RTR or hand built model, the printer actually pay's for itself very quickly, Using only a FDM printer makes the build process much simpler for building turnouts which can be printed to match existing RTR products

In fact you will end up with a highly detailed model not only in 32mm and 31.5mm gauges but I believe 33mm as well (to date I have not printed one or have the stock to test it). The appearance of these turnouts is quite stunning and the final result is aided by a bit of time carefully painting it

I would say Martin funds his experimenting and the running of Templot Club himself, I am certain he would welcome the odd donation towards the costs of both running Templot Club and his experimenting which in the end benefits us all if you use the programs or sites.
