A tele body is one of the easiest to do as it's flat and you can use a standard router base. I know what you mean about screwing up thing. Even now I have a moment of apprehension before making any critical cut. The old adage measure twice cut once still applies only with a router I'd say measure twice cut twice. In other words spent a good deal of time setting up and testing the cut on scrap. Get an old tele body and try it on that. Another thing I'd do is make up a bigger base plate for the router as it helps avoid tipping and gives it a more stable feel. If you are used to routing it isn't that hard a job.
Good advice. Thanks
