Binding rout problem

[Rogviler]

I'm sure there's a simple solution to this... If you're putting binding on a guitar that was previously finished or is already drilled for a jack, how do you keep the router bearing from going into the hole for the jack and messing up the groove? I thought of covering it with tape, but was wondering if anyone else had a better idea that would make for a smoother surface for the bearing to follow... Hopefully you know what I'm talking about.

Thanks for any suggestions.

Might want to buy a wooden dowel and plug it without gluing the plug in just for this purpose, then remove it when your done.
