This will be a relatively short post, explaining how to round a corner to a specified radius. Assume we want to round a corner to a 2″ radius.
The Sketch below shows a rectangular shaped piece of wood, with the upper left corner being rounded to a 2″ radius.
Notes & Explanation of Sketch above:
- Note #1, flags the rectangular shaped piece of wood whose upper left corner is being rounded to a 2″ radius.
- The cross hatched area is the wood being removed.
- Using the radius dimension (2″ in this case), two 2″ dimensions are marked as shown in the Sketch above.
- Note #2, points to the intersection of the two lines shown, and this intersection will be the point used for swinging a 2″ radius (as shown) with a compass.
- Note #3, angle between the two lines shown is 90 degrees. A combination square works nicely for drawing the line that’s at a 90 degree angle to the edge of the rectangular shaped piece of wood.
In closing, I have always found this method easy to use and easy to visualize how it works.
