FunctionFor the creation of customized slide rules.
The user first prints each slide with the appropriate scale(s). He then fixes the two edge slides (those with holes at either end) to the top and bottom edges of the slide rule base. Next, he places the moving slides between the edge slides. Finally, he places the plastic cover on top of the slide rule and hammers rivets through each of the four corner holes.
