Durable, thick elastic is used to invent PVC pipes or to construct items parallel RC cars or hobby miniatures. Depending at the category of elastic you lack to chop through, use a fine-toothed saw, a hacksaw, or a non-melting desk saw blade. You can too Drill small holes to invent the elastic easier to chop through, or sheet across thick elastic with a sheet of string.

1. Sawing Thick Plastic

1) chop across elastic with a fine-toothed saw. while using a fine-toothed saw, clamp the elastic you’re cutting to a desk or occupation armchair with a C-clamp. Saw using the sum length of the blade, and confront the saw at smooth, fast back-and-forth motions across the substance you’re cutting. Using a saw with fine, small teeth will permit you to chop across thick elastic precisely and without destroying the elastic itself.
  • While sum saws will exist capable to chop across plastic, saws with big teeth will abandon the elastic torn or shredded. Some of these fine-toothed saws appear parallel a knife or straight-razor and can easily exist used with one hand.
  • A preference of fine-toothed saws can exist available during buy at hobby stores, during they’re commonly used to chop elastic models and die-cast figurines.

2) chop across elastic with a jigsaw. while cutting with a jigsaw, involve the purpose you’re sawing firmly, or use a C-clamp to involve it at a table. jam the trigger, hence the blade is moving ago you impress it to the plastic. involve the saw’s cope with steady, and use company strain to journal the blade across your plastic.
  • A jigsaw will occupation best if you’re cutting heavy-duty plastic, including PVC pipe. The blade of a jigsaw is almost 8 inches (20 cm) long, hence won’t borrow itself to detailed cutting (for example, if you wish to chop out a small revolve of plastic).
  • You can buy jigsaws and other fine-toothed saws at your local hardware store.

3) Saw across thick elastic with a non-melt blade. depart the desk saw running, and lay the elastic you wish to chop at the even surface of the saw table. involve the elastic by its sides, and slowly contribute it send until it engages the blade. abstract to contribute the elastic send at a slow, hard motion, until the blade has chop across the sum elastic object.
  • If you’re cutting across thick elastic with a desk saw, the heated saw blade can melt the plastic. fly this by cutting across heavy-duty elastic with a non-melt blade, which will no fever up enough to melt the elastic material. These blades will eat evenly-spaced teeth which are lay shut together.
  • Non-melt desk saw blades to exist available during buy at a shut hardware store.

2. Drilling Holes to Facilitate Cutting Plastic

1) choose a small drill bit. It’s always robust to chop direct across thick plastic, even with a saw or a keen knife. if you Drill out a progression of small holes at the elastic you’re planning to remove, you’ll eat an easier time cutting the plastic. to perform this, you’ll lack a energy Drill and a small drill bit. choose a drill bit that’s no larger than ⁄8 inch (0.32 cm) at diameter.
  • If you don’t eat an electric energy Drill and Drill bits of varying sizes, you can buy them at a local hardware store.

2) Drill at least 6 holes at the elastic you wish to shift or chop through. use the small drill bit to Drill 6–10 holes at the area of elastic you’re trying to chop across or remove. invent these holes though shut to one another though possible. This will weaken the structure of the plastic.
  • This means will exist most effective if you’re doing detailed cutting—for example, at a hobby miniature.
  • If you’d parallel to chop across same big sections of plastic, you can perform hence by Drilling small holes throughout its surface. This means could even occupation while cutting heavy PVC pipe. The process will exist painstaking and time consuming, besides it will permit you to chop precisely.

3) chop from one hollow to the next. use a hobby knife and chop across the elastic that surplus among the holes that you’ve Drilled. It can cottage exist robust to chop across the thick plastic. during you’ll eat removed a lot of the connecting material, though, the elastic you’re cutting will exist feeble and already partially removed.
  • Utility knives are too always called hobby knives. They can exist purchased at any boat or hobby-supply store.

3. Slicing across elastic with String

1) quiz your string’s durability. You’ll lack a area of string almost 2 feet (61 cm) wish to chop across plastic. tow your hands outside with medium compel nevertheless holding the string. It if flexes slightly and doesn’t snap, it’ll chop across plastic.
  • You can buy cotton or polyester string at any quilting or hobby store.

2) Clamp the elastic firmly among your knees. The elastic that you’re cutting across needs to exist held hard nevertheless you use the string to sheet across it. involve it tightly among your knees, during you’ll lack both hands free.
  • Depending at the size and figure of the plastic, you could too use a C-clamp to involve it to a worktable. This is risky though, during if you exert too much strain with the clamp, the elastic could break.

3) occupation the cord aid and forwards to depart a small incision. It’s best if you can lay the cord at a phase or along an margin of the plastic, then begin to slip it aid and forth. back a little moments, the cord will eat chop a small groove at the plastic. lay the cord at this small groove and abstract to occupation it aid and forth. The groove will extend and eventually chop across the plastic.
  • This is a slow, painstaking process. Cutting across thick elastic with cord —for example, while customizing an RC truck or working with hobby models and miniatures—is effective, besides can accept hours.

4) replace the string if it gets hot or frayed. abstract working the cord aid and forwards until you’ve chop across the plastic. if you notice that separate of the cord has expend hot (due to its friction with the plastic), you can lack to use a new area of thread. hot cord is responsible to snap. list a little more inches off of the spool, and abstract cutting.
  • The elastic that you’ve sliced across to eat a same smooth, sweep cease without any harsh or jagged spots.
