Step 30: Router Mount Part 1

You are saying to yourself, what about my router and what if it's a different size. The method I chose will work for various router sizes. First, I measure the perimeter of the router housing. I use this number to find the radius of this perimeter. Remember in geometry and algebra class, there is this formula: perimeter = 2 (pi) (radius). With a little algebra, you can find the radius by dividing 2(pi) on both side of the equation to yield: radius = perimeter / ( 2 (pi) ). So now the radius is known, why the heck do we need it? You need to draw that circle on a piece of MDF stock to guide the cutting. Remember, we don't have a CNC machine to cut this hole for us. That would be sweet, though, wouldn't it? In time... in time.
