Band saws are the best tool for cutting a Pinewood Derby car block. If you don't have access to a band saw, a coping saw will do. Coping saws are economical and can cut unusual shapes and curves.

Coping Saws are intended for cutting curves in thin material but they can be used for cutting your Pinewood Derby car. The thin blades on coping saws make the saw tend to drift away from the desired cut so you need to carefully watch the cut. You will have better results if you are cutting a straight line it you use a Keyhole or Compass saw.

Never use a saw with teeth that are bent, broken, or dulled or a handle that is loosely attached. Nothing is more aggravating than working with a beaten-up or dull saw. Most saws cut when you push the blade into the wood but coping saws cut during the pull. This prevents the thin blade from buckling.

Before cutting your block, you will need to decide how your car will look. Draw some shapes on a piece of paper until youi decide on the shape that you would like to use. Now you can make a template of the outline of your car.

First, trace the outline of your Pinewood Derby car block on a blank piece of paper with a sharp pencil. Be sure that the axle holes are facing up. Mark the position of the axle holes on the paper as dots.

Next draw the outline of your car inside the block outline that you just made. Be sure that the outline stays at least 1/4 inch away from the axle holes.

Now carefully cut out your car outline and place it on the block. Be sure that the axle marks on the paper line up with the axle marks on the block. Then use a pencil to trace around the edge of the paper onto the block.

The result should look like this.

Next, turn your paper template over, place it on the other side of the block and trace its outline on the block. Make sure that the front of the car is on the same end of the block for both sides.

Example of a curve cut by a coping saw.

To begin a cut, set the saw blade down where the line you marked meets the edge of the block. Keep the saw at a right angle to the block so that it cuts through both sides of the block equally. Push the saw away from you. It shoud make a little groove in the wood. Lift the saw up and move it towards you and set it into the groove. Then push and pull the saw back and forth.

Keep a little pressure on the blade but don't bend it. Watch the blades progress along the line. It should follow the line on both sides of the block. If the blade starts to wander, twist the handle of your saw to glide it back.

Some general suggestions for sawing:

It is hard to start a cut at a steep angle. It will be much easier if you use a file or rasp to begin the cut then finish it with the saw.

  • Using a coping saw is a test of skill as it can be difficult to control and requires practice. You might want to make a few cuts on a piece of scrap wood before cutting your Pinewood Derby car block.

  • It will be easier to cut if you clamp the car block to the work surface. The line you plan to cut should hang over the edge of the surface.

  • Start by making short gentle strokes. Take longer cuts when the saw is a quarter inch or so in the wood.

  • Go slow, and watch carefully to make sure the cut is staying on the line. If the cut begins to wander, either start the cut from the opposite side or come in from a different angle.

FAQs

How to Use a Coping Saw? ›

For safety, keep appendages, hands and other objects away from the sharp teeth. Never apply more force onto the saw than you could using your bare hands. As with any other bladed tools, the user should wear long sleeves, padded work gloves and safety glasses to prevent bodily contact with the blade or cutting debris.

What are the rules for coping saw? ›

For safety, keep appendages, hands and other objects away from the sharp teeth. Never apply more force onto the saw than you could using your bare hands. As with any other bladed tools, the user should wear long sleeves, padded work gloves and safety glasses to prevent bodily contact with the blade or cutting debris.

What is the purpose of a coping saw? ›

A coping saw is a type of bow saw used to cut intricate external shapes and interior cut-outs in woodworking or carpentry. It is widely used to cut moldings to create coped rather than mitre joints.

Which way do the teeth go on a coping saw blade? ›

There is no “correct” position. The teeth can face in or out, and the blade can cut on either the push or the pull stroke. Typically the teeth face out and cut is on the push stroke, but do as you please - and no “law” says you have to be consistent.

What is the disadvantage of a coping saw? ›

The main disadvantage that I have found with the vast majority of coping saws is that the frame is not rigid – bends easily – and therefore does not follow a cut line.

Should a coping saw cut on the push or pull? ›

You can install the blade to cut either on the push or pull stroke, although for most work I find that a pull cut is easier to control. Of course, the saw gets its name from the coping cut used to fit molding together in place of a miter joint.

Why cope instead of miter? ›

Trim carpenters and other professionals often prefer coped joints because they tend to open up less than miters when the wood shrinks during dry weather. Coped joints also accommodate out-of-square wall corners better than miters, which require a 90-degree corner for a perfect fit.

What kind of cuts can you do with a coping saw? ›

The saw can simply and quickly cut coped joints for molding or curved parts for furniture and other work. Its blade can be threaded through stock to cut interior shapes or worked into tight places to trim waste from joinery. All this from a tool that's inexpensive and simple to maintain.

Do coping saws cut on the forward or backward stroke? ›

Hand coping saws were designed for a pull stroke. Period. Sure you can flip it around - but ask any seasoned wood shop veteran which direction gives you the most power and control and I'm sure they'll all agree - teeth towards the handle - pull stroke wins every time.

Why must the coping saw blade face the correct position? ›

Cutting on the pull stroke is more difficult to control and flipping long lengths of skirting board and supporting it for pull cuts is much more problematic too. A coping saw with the teeth facing away from the handle and toward the work means you can see the whole of the work from above.

What is a risk when using a coping saw? ›

Some people assume there's little-to-no risk of injury when using a coping saw, simply because it doesn't use any type of electrical power mechanism. While it's true that coping saws are completely manual, they can still cause serious injuries in the form of lacerations or even finger amputations.

Can you cut a circle with a coping saw? ›

The coping saw is just a narrow blade held taut in a C-shaped frame with a simple handle. Yet it can literally run circles around any other handheld saw, even a jigsaw. With a coping saw, you can cut out a heart in the back of a child's chair or make gingerbread trim for your roof eaves.
