Not sure is this is an error or me misunderstanding something.

Using the the experimental export of chairs. I seem to get two extra chairs in the stl export file that are not visible in the templot file:

Hi Tim,

Those are the crossing spacer blocks. They are not (yet) included on the trackpad view:

p,s. You haven't put a raft rectangle under the chairs. They will be awkward to handle printed individually.

cheers,

Martin.

Hi Martin. Thanks for the quick answer. I can see that these will help keep the clearences correct at this critical points. I assume that the real world turnouts use them as well. How are they fixed in the real world as they are between timbers? Are they welded to the rails or fixed in some way to the adjacent timbers?

I have discovered that my slicing program can create rafts for me that follow the shape of the chairs and this uses quit a lot less resin as they are not as thick as those produced in Templot

Hi Tim, resin is relatively cheap.
I would strongly recomend using a Templot generated raft , especially With the loose jaws.
Having a thin raft is a false economy.

What printer are you using?
if it is one that Martin ha recommended, be sure to use the profile that he has published.
If not one he has experience of make sure you have anti-aliasing switched off.
And be sure to use the right slice layer.

Hi Tim,

The prototype spacer blocks are bolted through the rails. They are not fixed to the timbers. One fine day we shall be printing the dummy bolt heads and fish washers to glue on the outside of the rails -- they are quite prominent:

And other track furniture such as the switch anchors.

p.s. this is another photo where the difference in colour between the galvanized chair screws and cast iron chairs is very evident.

Like almost everything else in Templot, you can set the raft thickness to whatever you want:

cheers,

Martin.

You really must watch James,s Bexhill West plug track videos. Unless you understand the basics it will not work. The fact is you probably have to watch the videos a few times, I still use them as a memory jogger

Those of us who are active have had the benefit of watching Templot develop over time, sadly there is no short cuts especially where resin printing is concerned. The chair rafts are important

The crossing spacer blocks are important in the build process for the common crossing, I strongly suggest you go over James's videos simply to familiarise yourself with the whole process

Thankfully you have shown me I have missed out a part of my instructions for the build process,
