Acoustic Guitar Construction

I will be trimming my top to the sides. My first choice is laminate trimmer with a flush cutting bit with a bearing on it. I am a little concerned about tear out. Any suggestions are greatly appreciated.

Best choice for top/back overhang #5089

Thanks Ken for your input. Would it be completely foolish to even try it with regular bit? I already know the answer most likely.

Straight and shear cut bits will work OK if you make your cuts using the same pattern as shown here:

The "down cut spiral bit" is simply superior in design and function -- the right/best tool for the job.

Thanks again Ken.

That's how I do it and follow the pattern. It's worked great for me.

I have used the KMG binding attachment on wood that I felt might be prone to tear out, i.e. cedar. It takes a bit more time since i can only remove small bites off of the wood, but it gave me peace of mind. I do not flush cut the top and back by the way. I cut them just a tiny bit deeper. When sanding the sides level, it is easier if you don't have to deal with the end grain of the top and back. Just my 2 centavos.
