How do you create a slide rule?

How to make a slide rule (or log-log or semilog graph paper)

1. Take an ordinary ruler, and put decimal points before the numbers marking the inches.
2. To position the major (black) divisions on the logarithmic scale, calculate the base-10 logarithm of each integer from 2 to 9 and plot the integer at that place on the ruler.

Does anyone make slide rules?

The only maker that still produces “classic” slide rules is the Japanese maker Concise. Made by various companies (e.g. Jeppesen, ASA), this simple and elegant device used by pilots for various flight calculations can also do basic multiplication and division on the circular slide rule portion.

What is slide rule answer?

The slide rule, or slipstick, is a mechanical analog computer. The slide rule is used mainly for multiplication and division, and also for “scientific” functions such as roots, logarithms and trigonometry, but usually not for addition or subtraction.

What is the purpose of a slide rule?

To serve as a mechanical analog computer
Slide rule/Purpose

Who made the best slide rules?

Reverend William Oughtred
The Reverend William Oughtred and others developed the slide rule in the 17th century based on the emerging work on logarithms by John Napier. Before the advent of the electronic calculator, it was the most commonly used calculation tool in science and engineering.

Are slide rules still used?

Slide rules are still commonly used in aviation, particularly for smaller planes. They are being replaced only by integrated, special purpose and expensive flight computers, and not general-purpose calculators.

Can I still buy a slide rule?

There are many pages about slide rules on the web, and you can still buy brand new slide rules (40 years old but never used, and still in their factory supplied box) in various places.

What are the example of slide rules?

A slide rule requires the user to separately compute the order of magnitude of the answer in order to position the decimal point in the results. For example, 1.5 × 30 (which equals 45) will show the same result as 1,500,000 × 0.03 (which equals 45,000).

What was the best slide rule ever made?

Faber-Castell 2/83N Novo-Duplex: Size 38 x 7 cm, 30 scales, plastic. This model is regarded by some as one of the finest slide rules ever made. Its combination of size, build, sophistication of scales offered and attractive use of colour gives a slide rule that impresses!

Can you build your own circular slide rule?

There are even some circular slide rules you can build. Scroll down about 2/3 of the page to see a nice wooden slide rule built by a man from Spain. (See the photo with this step.) Here is a basic circular slide rule design you can build.

Can you build a slide rule from a PDF?

If you would like to download PDFs of various classic slide rules and transfer them to your own base construction materials, this is the site you want. There are even some circular slide rules you can build. Scroll down about 2/3 of the page to see a nice wooden slide rule built by a man from Spain.

How difficult is it to do calculations on a slide rule?

Most calculations I have ever done on a slide rule involve basic multiplication on the C and D scales. The D scale is directly below the C scale visible in the photo. It is not difficult to set the factors and to read the answer on these scales without a cursor.

How do the screws on the slide rule stator work?

The screws near the T, K, & A scales fit into holes that are over-sized so the top slide rule stator can be moved a little left-to-right so the left indices of all scales align properly. The over-sized holes near these scales also allow the top stator to adjust in and out toward the slider for the desired smoothness of movement.
