Q4: What makes stainless steel stainless?

A4: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q5: Can stainless steel rust?

A5: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

This will help ensure that both sides of the joint are properly aligned and will fit together seamlessly. If you have a dovetail template or angle guides, you can use them to guide the steel square and simplify the process. Simply position the template or angle guide against the edge of the workpiece and use the steel square to mark the width and angle accordingly. Remember to always double-check your measurements and marks before cutting the dovetail joint. Accuracy is crucial for a tight and strong joint.

Q: How do you use a steel square to find angles for compound bevel mitered corners?: To use a steel square to find angles for compound bevel mitered corners, you would start by measuring and marking the length of each side of the corner on the respective pieces of material. Then, place the steel square against one of the pieces with the 90-degree angle aligned with the edge. Next, adjust the square to align with the other piece by rotating it until the desired angle is achieved. Finally, mark the angle on both pieces using the square as a guide, and cut accordingly.

Q: How do you use a steel square to determine the angle of a valley rafter cut?: To use a steel square to determine the angle of a valley rafter cut, you can follow these steps: 1. Place the steel square on the edge of the valley rafter, with one leg of the square aligned with the top edge of the rafter and the other leg extending towards the bottom edge. 2. Slide the square along the rafter until the bottom leg intersects with the roof surface where the valley rafter will be attached. 3. Once the square is properly positioned, mark the angle indicated by the intersection of the square's legs on the rafter. 4. Use a protractor or the angle measuring feature on the steel square to measure the marked angle accurately. 5. Transfer the measured angle onto the valley rafter by aligning the square's legs with the top and bottom edges of the rafter and marking the angle accordingly. 6. Finally, use a saw or other appropriate tools to cut along the marked angle on the valley rafter to achieve the desired cut. Using a steel square in this manner allows you to determine and transfer the correct angle for cutting the valley rafter, ensuring a precise fit and appropriate joint when installing it in the roof structure.

Q: How do you use a steel square to find angles for compound bevel coping cuts?: To find angles for compound bevel coping cuts using a steel square, the following steps should be followed: 1. Gain an understanding of compound bevel coping cuts, which are commonly used to fit two intersecting pieces of wood or other materials together. These cuts involve two angles: the miter angle, which determines the horizontal cut, and the bevel angle, which determines the vertical cut. 2. Begin by measuring the miter cut angle. Position the steel square against the material you wish to cut, aligning the long edge of the square with the material's edge. Adjust the square until the inside corner matches perfectly with the edge of the material. Read the angle measurement on the square's scale, typically marked in degrees. 3. Once the miter angle is determined, proceed to find the bevel angle. Place the steel square against the material's edge, aligning the long edge of the square with the edge. Adjust the square until the inside corner aligns perfectly with the material's edge. Read the angle measurement on the square's scale. 4. With the miter angle and bevel angle established, these measurements can be used to set up a compound miter saw or another cutting tool for making the compound bevel coping cuts. Consult the user manual or instructions for your specific tool to learn how to adjust the angles accordingly. 5. After configuring the cutting tool with the correct miter and bevel angles, carefully position the material and make the cuts accordingly. Take your time and ensure accurate adherence to the measurements and angles determined with the steel square. Remember that practice and precision play vital roles in achieving precise compound bevel coping cuts. It may require some trial and error to attain the perfect fit between the coped piece and the other material, so exercise patience and make necessary adjustments.
