It all began some time ago, when I had to deliver 50 round plaques, The round plaques were made of brass and had to be mounted on a 12" wooden circle.. I decided to use MDF board to mount the brass plaques.. the wooden board was to be stained and finished in Mahogany.. Drawing 50 circles accurately did pose a problem, so I came up with this quick invention.... I found this strip of (SWG 18) brass in my workshop and drilled two rows of holes as shown in the picture, the holes where drilled by a 2 mm drill bit, which is just right for a lead pencil point or a ball point pen....

Step 1:

Decide where to locate your center point and pin the tool with a drawing pin as shown, place the pencil or ball point of the pen at the required distance or diameter of the circle... and begin drawing the circle..

Step 2:

Complete drawing the circle, extending pressure towards the outer radius.. simple and easy......

Step 3:

Circles can be drawn with great accuracy, simple quick and fast..... believe it or not this tool has been with me for over 15 years... Can the ancient geometry compass be redesigned for the convenience of students....?? I think so... Happy Circles...

<p>I have done this with old rulers before. It works great for making templates.</p>
Thanks for your enterprising comment, I used brass because it becomes unique....
<p>With Compliments from me to you... Happy Circles.....</p>
