Guitar Making Tip No. 741

Guitar Making Tip Number 741 is about the circle cutter. On the drill press, you can buy a tool called a circle cutter, or wing cutter. This is a great option for rosette making. The tool makes large round cuts in wood, and can be used for a lot of things. Here is how.

Rosettes and Cutting Circles

guitar making tip number 741There are a number of ways to hand cut rosettes. They have been hand cut for centuries, so you are in good company if you hand cut yours.

The only down side to hand cutting the rosette cavities is that its time consuming. If you are half way good with a chisel, you can do the job if you are patient.

However, getting the outside and inside lines nice and straight can be tough as a beginner.

An alternative that can give you a lot of help with the bordering of your lines on concentric ring or round rosettes is the circle cutter. This tool fits in the drill press chuck, and you can move one or two cutters on a shaft. The cutters are locked in place, and advanced into a piece of wood. Spinning, they cut circles according to how they were set.

Buying a Circle Cutter

I have used cheaper circle cutters forever. They have always worked, and the results were always good. If you have access to a finer tool, don’t shy away from it. The lower end ones work too, so don’t worry about buying from a discount tool store.

I recommend that you but a tool that has two cutters. This is for a couple reasons. Not only will the tool be more balanced when it turns, but it will also work faster. With dual cutters, you can cut the inside and the outside of a ring at the same time.

Cutting at the same time gives you more freedom to create. You can set the tool on a scrap, and then turn it loose on the guitar. You get faster feedback on your creative decisions, and this helps everything move along better.

What to Do After You Cut

The circle cutter is really good at taking out the edges. It’s not meant for the middles. The line that you will get around the edges of the rings cannot be beat though, so the tool has a lot of value.

You have a couple options for taking out the middle. First, you can use a router or a Dremel to do the work. Since the edges will already be clearly defined, you will not have to get too close to them.

Alternatively, you can use a chisel to remove the middles by hand. Since the depth of the edges and the edges themselves were already set with the circle cutter, removing the middle portion with a chisel is fairly straight forward.
