# How do you figure out angles?

## How do you figure out angles?

The formula for finding the total measure of all interior angles in a polygon is: (n – 2) x 180. In this case, n is the number of sides the polygon has. Some common polygon total angle measures are as follows: The angles in a triangle (a 3-sided polygon) total 180 degrees.

## What angle is a cross cut?

Start by setting the miter gauge to 45 degrees (Photo 1). Mount an extension fence, moving it toward the blade far enough to cut the end at a 45-degree angle (Photo 2). Then make the fine cuts on your material. Hold your material very tight; the saw blade will try to pull it off line.

## Is the jigsaw best for straight cuts or curves?

Jigsaws are ideal for cutting curves and complex shapes in wood (Photo 1). They also work well for making short crosscuts on a board (Photo 2) and finishing inside corner cuts (Photo 3) that you start with a circular saw. Jigsaws are not good for making fast, long, straight cuts. Use a circular saw instead.

## Can you cut a 2x4 with a table saw?

You can rip 2 x 4 on a table saw effectively provided you set the rip fence correctly, use proper technique and use the right tools. The proper technique while ripping a 2x4 is to apply pressure in three directions, that is, against the rip fence, forward (for pushing the wood) and downwards for keeping the wood flat.

## What are the two devices that are used to guide stock when cutting with a table saw?

Never Free-Hand a Cut When using a table saw, the woodworker should never attempt a free- hand cut. Instead, use the fence or miter gauge to guide the stock.

## Is it safe to rip stock with the splitter in place?

Do not rip without using a riving knife, splitter, featherboard, or other device to keep the workpiece against the fence throughout the cut. Never cut freehand without a fence, miter gauge, or other guide, and never grab the offcut while it's being sawn.

## What PPE should be worn on the table saw?

Wear safety glasses with side shield or safety goggles, or a face shield (with safety glasses or goggles). Wear hearing protection that is suitable for the level and frequency of the noise you are exposed to in the woodworking area. Wear protective footwear, when required. Wear respiratory protection, when required.

## What can you not do on a table saw?

Do not make free-hand cuts on a table saw. Guide the stock through the blade using the rip fence or the miter gauge. Keep the blade guards, splitters and anti-kickback fingers in place and operating freely. Check the action of these items before starting work.

## What causes kickback on table saw?

The two main causes of injury from kickback is trauma from the wood striking the head, chest, or torso of the woodworker, or the wood moving so quickly that an operator doesn't have time to take their hand off of it and it gets pulled across the saw blade.
