Mild Steel Checker Plate

You will need:

• 2 straight edges
• A curved corner

Step 1. Place a straight edge along each surface edge of the curved corner as in the diagram below and mark the points where the curve starts (A)

Step 2. From (A) create straight lines so that they both meet to make a quarter of a circle.

Step 3. Measure the length of each line, they should be the same. This is your radius.

If you have access to a printer you can also use this handy template to measure the radius of a corner. Make sure you change your print settings to print to actual size. Once printed you can check its actual size with the reference scale and a ruler.
