Here's a neat little trick, neat way to to put in the corner radius...

========
Finding a Corner Radius

I often need to make a rounded corner on a workpiece.

But this can often lead to a lot of trial and error until I get the corner radius just right.

You’ll find a carpenter’s square and a compass makes this task quick and easy. And the results are perfect every time.

For example, I needed a 4″ radius at the corner.

So I lined up the edge and end of the workpiece with the 4″ mark on the outside of both legs of the square (see photo below).
Then I marked the point of the square.
Finally, put the pointed arm of the compass on this mark, extend the compass to the edge of the workpiece, and scribe the line, as shown in the photo.


Good Woodworking,

I cheat worse than that --
I make note of the diameter of common household items.
A quarter is 1" (1/2" radius), the lid to my plastic water bottle is 2", the lid to my travel mug is 4" (2" radius) etc etc ----
When I am real lazy -- I just scoot the desired item into the corner and trace the edge.

But yes - I agree that's a great and quick way to find a desired center point.
And certainly more versatile.

When I see things like that Bj. I can't help thinking "now why didn't I think of that"
Thanks for passing it on.

Not if the paint can (or other item) is handy and happens to have the exact radius you are looking for.

But yes - for the 90%+ of the time when they don't -- a square and a compass is an excellent way to go.

A common variation of that idea -- if you don't have a compass handy or if you need a radius larger than your compass allows for - is to put a thumbtack at your center point and use a piece of string tied to the point of your pencil.

Hi BJ

Well, nice trick he has but, framing square is too big (for me) and must be supported for accurate marking (as you can see on the picture...)

I do it a little bit different and get the same result by pre-setting the stop on the ruler, line from one side, line from the other side, stick the compass in the intersection and go.

Just for the photo, I used 2 rulers but actually, I'm using only one.

Hi niki

Like you I'm not to crazzzzzy about using the framing square I now use the Incra Rules, they are Dead ON...
As you know the size of the pencil lead can put it off just a bit but with Incra rules, they took that error out of it..
