Need some help

[sazdaman]

Well, I guess it's time I reach out for some help on this one. I'm currently in process of making a bass guitar. It's close to being complete, however I have two routing cavities that still need to be routed out that I may need some help on. The bass is not flat, it has a radius to it. So just putting the router on top will not suffice.

Originally I used a 1/2" straight bit with a bearing that rides up against a template of hardboard. This doesn't work because the bearing eats into the template.

So what should I do?

Could you make your template from 3/4" mdf and then shape the underside so it matches the radius of the guitar? THat would give you a flat top surface for the router base.

If your bearing is eating into your template, it may not be rotating properly. Just a thought on something to check.

You could drill out the majority of the cavity and finish with a chisel or a router plane.

Thanks guys. I got it figured out. I opted to use a straight bit with no bearing and a bushing.
