My first post was back in February - before I had even purchased a 3d printer, and it is now November and I am writing the introduction... This blog is all about my experiences for 3d printing. It is a way for me to share what I learn along the way, and to show off what I have created. Most pages are tagged Model and are about a specific model, and the prototype it is based on. Generally I try to visit the prototype, and include a couple of photos of that for comparison. I also try to learn the history of the building, which is not always easy, and record that on the page too. A lot are buildings in and around Preston, as that is where I live. Models are further divided into Building , Railway (i.e., railway-related buildings), Feature (bridges, tunnel portals, etc.), Rolling Stock , Vehicle and Clutter (smaller items) In addition, there are pages tagged How to and Prototype . If you want to know how to use Blender to make 3d models, there is an article I wrote on another s...
Around Easter I pre-ordered a mini-heater for my printer, in readiness for the winter. It arrived a couple of weeks ago, and today I fitted it, as the temperature in the garage was 13°C at 8 am this morning. The instructions are rather unclear, but there is a video here: https://www.youtube.com/watch?v=S7o60xKvTeM And it was actually very simple - though easier if you have a friend to hold it while you put the screws in. Here it is in place, and in action. My first heated run is going! ETA: The run, and and a subsequent one, went fine. The temperature - as it reports anyway - was between 25.0 and 26.0 every time I looked at it. Have to wait and see how it copes when the ambient temperature is sub-zero, but looking good! ETA: Now November, and getting cold. The temperature it reports is about 5 degrees less than my thermometer - not sure which is right, but I suspect not the heater! But does it matter? As long as it is consistent, that should be fine, and it is having n problem ge...
Plate girder bridges consist of typically two girders across the span. In the half-through version, the deck is suspended from the bottom of the girders so there is greater clearance below, with the train running half through the structure of the bridge and half below. All the railways approaching Leeds station are elevated, and where it crosses a road these types of bridges have been used extensively. I would guess they are original, and would have been built by various railway companies, so a mix of designs is in evidence. Water Street (Wortley and Leeds line) We will start with a disused railway crossing Water Street. I believe the top third of the bridge is on top of the girder and is just fencing, rather than structural. Despite the railway being lifted, it is still apparently maintained, though the next one along is not. Looking underneath we can see more details. The cross-girders are clearly seen. These are always perpendicular to the bridge, whatever angle of skew of the ...
