To add cornstarch as a thickener, first, create a slurry by mixing equal parts cornstarch and cold water. This step prevents clumping when added to a hot liquid. Gradually stir the slurry into your sauce or soup over medium heat. Allow the mixture to simmer but not boil vigorously, as overheating can break down the starch and lose its thickening power. The general ratio is 1 tablespoon of cornstarch to 1 cup of liquid for a medium thickness. It's important to note that cornstarch should be added towards the end of the cooking process because prolonged heat can cause the sauce to thin out again.
When drilling into PVC, it's essential to secure the pipe to prevent it from spinning or moving. Use a clamp or vise to hold the PVC pipe in place on a stable work surface. Make sure the clamp or vise grips the pipe firmly but not so tight that it deforms. Another method is to use a custom PVC holder or a homemade jig designed specifically for holding PVC pipes. When drilling, apply steady, moderate pressure, and start with a small pilot hole before drilling the final diameter. Use a sharp drill bit suitable for plastic to avoid cracking or melting the PVC. Safety glasses should be worn to protect your eyes from plastic shavings.
Gluing ABS (Acrylonitrile Butadiene Styrene) to PVC (Polyvinyl Chloride) can be challenging due to their different chemical properties, but it is possible with the right approach and adhesive. The key is using a solvent cement designed for both ABS and PVC. These specialty adhesives can create a strong bond between these dissimilar plastics. To ensure a strong adhesion, first clean the surfaces with a mild solvent to remove any oils or debris. Apply the solvent cement evenly on both surfaces and join them, applying firm pressure to ensure a good bond. It's crucial to allow ample drying time, as recommended by the adhesive manufacturer, before subjecting the joint to any stress. This method is useful for non-pressure, non-structural applications, as the bond may not have the same strength and durability as a weld or a connection between like materials.
