You can cut a perfect circle top using your table saw. To do this, you will need a jig (a large sheet of plywood with a pin on which the board being cut spins). Cut off corners (on the work piece) to remove large amounts of excess material. The first set of cuts take a square piece to an octagon.

For the construction of a circle, we need a ruler and a compass. This is the centre of the circle. Turn the extended pencil-arm of the compass through 360 degrees to draw a full circle.

Continue cutting corners until your workpiece is roughly round, then slide the jig forward, beyond the blade’s front teeth, and rotate your piece clockwise to form a perfect circle. Keep sawing off more corners of the piece to form an octagon, then a 16-sided piece, and so on until it is roughly round.

This Is Very Easy And Useful Trick To Cut Circle Of Different Diameter. Start by tracing the jigsaw on wood with an inch offset on all sides. Then mark a hole where the jigsaw blade will go through and use the drill press to drill it out. Then take four one-inch plywood pieces and glue them on the jig base.

The first tool that comes to mind for cutting curves is a jigsaw, but if the curve is gradual, try a circular saw instead. It’s surprisingly quick and easy to cut a smooth curve with a circular saw. This method is for cutting rough curves. The thinner the material you’re cutting, the sharper the curve can be.

We recommend a solid-carbide upcut spiral router bit. For the Model 300 Circle Guide, use a 1/2″-dia.

Cutting a Circle in Wood with a Hole saw. Using a hole saw is the absolute easiest way to cut circles in wood for your project. All you have to do is lock your hole saw in the chuck of your drill or drill press and start cutting. You can use hole saws to cut circles from ¾ inches up to 7 inches in diameter.

Cutting a circle out of wood is usually done with a jigsaw and takes a very steady hand. A router is a more precise way to cut a circle, but it takes some time to set up a jig. If you’re willing to drill a hole through the top of your table saw, you can start cutting circles with it right away.

Place the center of the circle cutter in the center hole and bit in the hole for the circle. Hold the Rotozip upright in one hand, turn on the Rotozip. Hold the outer knob of the circle cutter with your free hand. Turn slow counter clockwise letting the bit do the work.

Because your circle is so small, use a small scissors or manicure scissors. Cut counter-clockwise around the circle (unless you are a lefty). Because the plastic is quite thin, it will not hold up well to a rotary cutter such as a hole saw or similar cutter. A trammel type cutter would likely be much worse.

The three best types of saws for cutting thick plastic are a fine-toothed saw, a jigsaw, and a table saw.

• A fine-toothed saw works best for precision plastic cutting.
• A jigsaw is ideal for cutting thicker pieces of plastic like piping.
• A table saw excels in cutting through bigger plastic pipes or thick plastic blocks.

The Circle Cutter makes it easy to cut circles anywhere on your crafting material, perfect for creating windows on homemade cards, scrapbook pages and more. Cut circles from 1″ to 8″ with no preset increments. Additionally, it includes a gripper foot on the bottom to prevent slippage when you’re cutting.

How To Cut A Circle In Plexiglass By Hand

1. Put the sheet on a working surface.
2. Mark the points where you need to cut through. Use a tape measure or ruler and a pencil.
3. Use a glass cutter to cut through the marked points. It will take around 10 cuts.
4. Break the plexiglass by applying a downward force.

One way to cut circles into plexiglass by hand is using a hole saw. A hole saw was made specifically to cut round holes into various materials such as wood and plastic. It can also easily work its way through plexiglass. Another way to cut a circle is using a jigsaw.

Fit a circular saw or table saw with a fine blade with crosscut teeth to prevent chipping the piece during the cut. Line the plexiglass sheet along the cut line. Use the saw at a slower speed, or keep the material cool by spraying water over the cut point during the saw operation.

The key to cutting acrylic with a jigsaw is to keep the speed low. If you cut too fast, the acrylic will melt from the heat the friction creates, and your project will be a mess! Apply a strip of painter’s tape to the cut line to prevent cracking.

A Dremel is commonly used for many applications, including cutting glass. Acrylic is a clear plastic also commonly called plexiglass. It is much stronger than glass and serves the same purpose. Using a Dremel is one of the best options when cutting acrylic, and it’s an easy enough task for most homeowner to take on.

Home Depot does not cut any glass, including plexiglass. You would have to take it to a window/glass specialist/specialty store, or special order your piece through the Customer Service or Millworks desks.
