Here is a set of sketches for scratch building an all concrete coaling tower. Prototype still standing in my town, is 120’ high. Footprint is only 2 3/8” x 4 7/8” or 2 3/8” x 6 ½” (two versions) but it’s 9” high. As a young boy, I can remember walkways and handrails on it, but they were torn down for safety reasons many years ago.
Choice of materials is up to you. It can be done in wood but sketches are based on styrene thicknesses. If you use another material adjust dimensions accordingly. Painting this structure is not recommended until you use a filler on butt joints and sand smooth. For gluing styrene parts I recommend a plastic solvent type glue.
The building directions are in the sketches, and to make your build easier you can enlarge them to full size and print them out. Read directions in assembly sketches before cutting out parts as you may want to change some sizes or cut fewer, or additional, openings.
Included sketches are: Overview sketches, Part templates, Assembly sketches, and pdf’s. Also included is one prototype pic. Parts are relatively large, so there are 10 pdf's.
To print the part templates actual size, use the PDF's. Select best printer quality, set PDF zoom to 100%, and page scaling to "none" or actual size. Check your printed page to see that 3" lines are exactly 3" long. Once you have template printed, you can cut with scissors (leave a 1/8" border) and arrange on your material for maximum sheet usage. Part templates for siding are a mirror image, when needed, so that you can cut walls with siding side down (easier to cut). Be sure siding grooves are oriented correctly. Use rubber cement or Krylon Easy Tack Repositionable Adhesive to glue paper templates to your material and then just cut on lines. No measuring ! Paper comes off easily.
Cut out parts carefully using a SERB (Single Edge Razor Blade) and straight edge, then follow assembly sketch directions.
