Roger that. 
Thanks for the correction.

Engineer's scale rules measure in tenths and other odd scales, don't you
mean an architect's scale rule? They're in fractions:

Some scales to help with reading your blueprints:
In our case 3/4" = 1'0" which comes  out to  1/16th of a inch = 1 inch on the prints.

Conversion Table: True Size (Feet) to Scale Size (Inches):


The following table, developed by Ken Dorr, allows you to convert dimensions on prototype, measured in feet, to dimensions on a model, measured in inches. To use the table, find the prototype dimension in feet in the left hand column. Then translate across until you reach the scale column for the scale of your model, and read off the scale dimension in inches. If the dimension you are looking for is not on the chart, you can find it by adding two other dimensions. Example #1 : A plank on the original ship is 20 feet long. To determine the length of this plank at 3/8"=1' scale, find the row for 20 feet, then translate across to the column labeled 3/8. The value at the intersection (7-1/2) is the length of the scale plank in inches. Example #2: A ship's boom on the prototype is 38 feet long. You which to determine the scale length of the boom at 3/16"=1' scale. Since this value is not shown on the chart, two look-up operations are needed. First, look up 30 feet in the right hand column. Translating across to the 3/16 column, we find the value 4-5/8 inches. This gives you the length of a 30 foot boom at 3/16"=1' scale. Next, starting in the left-most column with a length of 8 feet, translate across to the 3/16 column. This gives you scale length of the remaining 8 feet, 1-1/2 inch. Adding the two scale sizes together, you find that the length of the 38 foot boom is 4 5/8 + 1 1/2 = 6 1/8 inches in length at 3/16"=1' scale.

I will be building a Tennessee # 359. And I will also be having live hangout sessions talking about the boat and other related things with up to 9 guest. Please feel free to Join in and share your adventures.
