How to model a television dial? I'm trying to model this dial and for some reason I'm totally stumped on how to do this without too many booleans and to make it smoother than the rest of the tv.  I've been watching tutorials, but the few I found were more how to make the a knob separately and from a side view rather than front (which is what I'm doing).  

If you need the .blend I've attached it, but any simple example or tutorial suggestions would do...not trying to get anyone to do the work for me ;)

Here's the image:



And here's what I have so far with a boolean...I just have the feeling this is the wrong way to go about this:
A common way to do that is create a hole in the surface, add a circle into that space then fill in the gaps. 

1 : Subdivide a plane and delete some of the inner vertices.

2: Add a circle with a vertice count the same as the number of vertices that now make up the inner edges of the plane.

3: Select both the circle and the inner edges of the plane, then using the W shortcut key open the Specials menu and choose Bridge Edge Loops.

4: Using the Extrude tool model the rest of the Dial.

5: Add bevels and or supporting edge loops, smooth….. etc  etc .

Note that if you intend to use a Subsurf modifier then aim to use a circle with less vertices than in my example below.



Check on Youtube for cutting holes in meshes. This is a good example https://www.youtube.com/watch?v=Bc52fcrHvAA
