Center Channel

Hello Everybody,

I have a simple solid part: 4" long, 3" wide, .75" thick.  I simply need to make a 5/8" wide channel, 1/4" deep lengthwise in the center of the part.  I dont know how to get the center of the channel exactly in the center of the part.  I have a center line on the part, but how do I extrude a channel centered?  having a little problem here.

Thanks for the help
