Almost every woodworker comes across a project where he or she needs to cut a perfect circle. Whether you're building a custom speaker enclosure for your car or home or building a round table, having the right tools to cut circles can make a big difference. You could rough out the circle with a perfect circle router jig values saw then use a template and a flush-trim bit on your router to clean it up.

Or you could use a jig on the band saw to cut a circle. These all work to a degree but aren't as easy to use or as accurate as a hand-held router and a Jasper Circle Guide. Jasper Circle Guides are designed with details to make it easy to rout perfect, smooth circular cutouts. You can use other bit sizes, but you have to do some math to be able to set the jig perfect circle router jig values the proper radius before cutting a circle.

And similar to the Modelif you want to make a circular cutout instead of a disk, you'll need to account for the bit diameter. The Jasper Circle Guides replace the baseplate on most routers we recommend using a plunge router.

A hardware pack is included with mounting screws to fit your router. The process of installing and centering the Circle Guide is similar for both the Model and Model After removing the baseplate from your router, align the mounting holes on the Circle Guide with those on your router before loosely installing the appropriate screws.

Now, plunge the router so that the centering pin slips through the hole in the centering disk. Tighten the mounting screws to secure the Circle Guide to your router. We recommend a solid-carbide upcut spiral router bit. While you're at it, tap out the centering disk from the Circle Guide. Just remember to re-install the disk when storing the Circle Guide. The key to cutting precise circles and cutouts is in the scales printed on the Circle Guides. They may look a little perfect circle router jig values at first, but once you take a few minutes to understand how they work, using the scales becomes second nature.

But before I get into the details, there's one thing I need to mention. The Model Circle Guide was primarily designed for use by car audio professionals making custom speaker enclosures. So the readings for the pivot hole values on the scale are for the diameters of the cutouts and not the size of the disk.

You can use the Model to make circular disks, such as small tabletops, but you'll need to account for the diameter perfect circle router jig values the router bit more on that later. The scale on the Model Circle Guide is for cutting out holes at a given diameter. Click to perfect circle router jig values a larger image.

The first, and most obvious, thing to know is the diameter of the cutout you wish to make. You look at the bottom of the printed scale for the whole number of inches, which is 8" in our case.

Where the two lines intersect is the center of the circle and where the pivot pin will be located. It's that simple! The process I just described creates a circular cutout or hole at the diameter chosen for the pivot hole value. If you want to create a disk a specific diameter, you need to use just a little bit of arithmetic. All you do is add twice the bit diameter from the desired hole size.

This tells you where to locate the center pin on the pivot hole scale. The scale on the Model Jasper Circle Guide was primarily designed to cut out larger disks, such as round tabletops. Finding the correct pivot hole location works the same as on the Model To create cutouts instead of disks with the Modelthe pivot hole location will be the desired diameter perfect circle router jig values the cutout minus twice the bit diameter. For cutting out a tabletop where you don't want the hole to show in the finished piece, simply drill a blind hole on the underside of the workpiece.

What if you don't want to drill a hole into the workpiece? There's an easy solution: Use spacer blocks. Then attach a couple squares to the bottom of the Circle Guide, positioning them under the router. The video below shows what I mean. Once the pivot hole is drilled, all that's left to do is position the Circle Guide over the pivot pin at the correct location.

But before you start routing, place a sacrificial backer board under the workpiece so you don't accidentally rout into your perfect circle router jig values when cutting out the circle.

I like to attach the workpiece to the backer board with double-sided tape. Make sure the entire assembly is secure before routing. Continue lowering the bit to make several passes until you just cut through the workpiece.

That's it! Using the Jasper Circle Guides makes routing perfect circles quick, easy, and accurate!
