The most suitable fixing to use when fixing 12mm plasterboards to a timber stud is 35mm Drywall Screws. Drywall screws are specifically designed for attaching plasterboards to wooden studs, providing a secure and reliable hold. The 35mm length is appropriate for the 12mm thickness of the plasterboard, ensuring that the screw does not penetrate too far into the stud or leave the plasterboard loose. Using drywall screws in this scenario would result in a strong and durable installation.

A compound miter is not cut at just one angle. It is a type of cut that involves both a miter angle and a bevel angle. The miter angle determines the horizontal angle of the cut, while the bevel angle determines the vertical angle of the cut. This allows for more complex and precise cuts, especially when working with crown molding or other angled cuts. Therefore, the statement that a compound miter is cut at just one angle is false.

By planing a leading edge on the lock side allows clearance when swinging shut, you can also plane a leading edge to the hinge side, this helps to stop the door binding. As the size of the door gets wider say with 45mm or 54mm doors you really do need this leading edge especially if it has brush strips.

False.

You would typically use a longer spirit level, often 4 or 6 feet in length, to fit a door lining. These longer levels provide greater accuracy and help ensure that the door lining is perfectly level and plumb. A 2-foot spirit level might not provide the necessary precision for this task.

When fixing guttering, two tools that would be useful are a cordless screwdriver and a string line. A cordless screwdriver is necessary for removing and replacing screws that hold the guttering in place. The string line is used to ensure that the guttering is properly aligned and level. This helps to ensure that the guttering functions correctly and prevents any water leakage. The other tools listed, such as the block plane, marking gauge, 25mm chisel, and claw hammer, are not typically used for fixing guttering.

In order to strengthen a stud frame wall, it is necessary to add noggins in between the studs. Noggins are horizontal pieces of timber that are placed between the vertical studs to provide additional support and stability to the wall structure. They help to prevent the studs from twisting or warping and enhance the overall strength and rigidity of the wall. By adding noggins, the stud frame becomes more robust and capable of withstanding various loads and forces.

A 6mm plywood would be most suitable for a pipe boxing because it is thin enough to be easily cut and shaped to fit around the pipes, while still providing enough strength and stability to support the structure. Thicker plywood such as 18mm, 22mm, or 25mm would be unnecessary and potentially more difficult to work with for this purpose.
