Photo 20 This shows one of my two portable boxes that I carry around where ever I travel so that I can build when the desire strikes, There is a large selection of dental tools files and miniature hand tools, clamps, scissors, knives, etc. Photo 21 For forming curves and dome shapes I use a jewelers dapping set that consists of a steel block with various size concave shapes machined into it and a set of various sized ball shapes that can be used to work a shape into paper parts. Also I use a wood block with larger concave shapes and a wooden press rod with gently rounded ends. Sometimes the block is not really needed and I use pieces of cut up mouse pads to work in shapes with dapping tools, rods, needles or whatever. You can buy a dapping set on Ebay for around $60. Wooden ones are around $10. Photo 22 Some useful tools are shown in photo 22. From left to right are a scribing tool (Radio Shack) useful for scribing fold lines. This scriber also has a slotted end that can grab a paper piece that needs to be rolled and will hold it while you wind the paper around the shaft. I also use a draftsmen's pencil with extremely fine lead, art pens of variousl colors for edge coloring (I have maybe 50 different colors), fingernail file (course on one side - fine on the other), and very fine artist brushes for touchup work.
