Thanks to ranulf(Ian) for providing pics of this tower from Durango Colorado, I was able to scale and make this scratch sketch set of the Durango and Silverton dispatch office. Footprint is 1 x 1 1/4 so it's small, but is almost an exact duplicate of the existing structure. Designing this for a sketch set was difficult for 2 reasons. One, proper sized windows were hard to find, but Rusty Stumps were doable. Second, the composite nature of the side walls made drawing, as well as construction, slightly difficult, but slight modifications made it possible. It is because of these reasons, that this set is not recommended for novices. The stairs kit from RSLaserkits is also a craftsman kit.
It can be done in wood but sketches are based on styrene thicknesses. If you use another material adjust dimensions accordingly. Paint parts before assembly, except where the edges glue to other parts.
The building directions and materials 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, Parts templates, Assembly sketches, and 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 and straight edge. The best way to cut out window openings is with a corner punch. It is important to follow assembly sketches IN SEQUENCE or some parts may not fit.
