"Model RR scale rule 12"
The Model RR scale rule is easy to read. I need the rule to convert real world feet to HO scale it does that very accurately. The addition of a table of decimal equivalents for number drills is helpful in determining size to use for building structures.

"Must Have Tool for Any Skill Level"
The Mascot Model Railroader Scale Rule provides quick reference for measurements in N, HO, S, and O scales, with a 12 inch, made in the USA, stainless steel ruler. In addition to the scale measurements are a 100mm ruler and a 5 inch ruler showing 1/64 inch markings. Also included are a quick reference chart for converting drill bits to decimals, i.e. bit #80 is 0.0135 inches, a reference chart for tapping and screw sizes, and multiple formulas for common scale measurements. The ruler is thin and lightweight yet sturdy and could be used as a straight edge for scoring in a pinch.

"Must have scratch building tool"
Incredibly useful tool for scratch building - so much easier than constantly multiplying and dividing by 87!!!
