Mobile phone mast

 This was in response to a request, though was something I had vaguely been thinking of doing for while.

The model is pretty straightforward. A simple repeating unit makes the tower itself. Cabling is NURBS with a bevel; not sure how visible at this scale.


There are several different designed, this is loosely based on one at Settle Station.


I do not know about mobile phone masts, but I guess the thin rod on top is a lightning conductor. The white boxes are microwave transmitters, which have a wide spread, so between the three they cover the area for mobile phone connects. The dishes, on the other hand, are directional, and presumably connect to a base station or another tower to form a network.

Introduction to the Blog

 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...

Various tank wagons

Image
I am a chemist by profession, and so the transport of chemicals by rail is of interest. In fact I wrote an article on the topic, see here . Nitrogen Liquors The appeal for these is in the name, which makes no sense at all if you are a chemist. They actually contained ammonium nitrate, which is a fertiliser used to put nitrogen in soil, which will be where the name comes from, presumably a solution in water, that is likely both hot - given the wagons are lagged - and very concentrated. Images of the prototype can he found here . They are so dirty it is not possible to tell the original colour, but I am guessing green? One end has four flanges; these would have been to allow the contents to be heated using steam. They were printed separately. The wagons have channels down the sides to catch spills. i guess this is to ensure the solution down not end up between the rails, where it could mix with oil to create an explosive mixture. The ladders are brass. The chasses are Peco. Carbon Dioxid...

Safety First!

 They are hazards associated with resin 3d printing, and you should be aware of them and act appropriately. What do I know about it? I have worked in the chemical industry for several decades, part of my job is writing safety data sheets and I currently serve on a committee reviewed safety across an entire chemical plant. That said, I am not an expert on resin, so this is only a guide. You are the one who is ultimately responsible for your safety! iso-Propyl Alcohol (IPA) IPA is harmful and flammable. Keep it away from naked flames and electrical sparks. That said, with a flash point of 12°C, it is safer than acetone (-18°C) or petrol (-43°C). Do not drink it. Yes, it has alcohol in the name, but it would still be bad for you. Try to keep it off your skin, but it is not that big a deal. IPA was the main ingredient in the hand wash we were all deliberately putting on our hands during "lockdown", so it is really not that hazardous. If you have a reaction to IPA, it is more like...
