To measure PVC for a greenhouse, start by determining the dimensions of your greenhouse (length, width, height). Decide on the frame's structure, including the roof's shape (e.g., A-frame, dome, or quonset). Calculate the total length of PVC needed by adding the lengths of all the sides, roof ridges, and cross supports. Consider the diameter of the PVC, typically 1/2 inch to 1 inch, based on the greenhouse size and the intended durability. For accuracy, sketch your design, noting all measurements. Include extra length for connecting pieces and potential adjustments. Don't forget to account for PVC for door frames or additional supports if needed. Lastly, consult with experts or experienced builders to validate your calculations before purchasing materials.
On the TV series "Forged in Fire", participants often use various types of adhesives for attaching handles to their blades, with epoxy resins being a popular choice. While the specific brands may not always be mentioned, a high-quality, strong, and durable two-part epoxy resin is typically sought after. These epoxies are favored for their long-lasting bond, resistance to heat and chemicals, and the ability to fill gaps, making them ideal for securing handle materials to metal. Brands like J-B Weld, Gorilla Epoxy, and West System are often recommended by knife makers for their reliability and strength. Choosing the right epoxy is crucial for the functionality and durability of the knife, emphasizing the importance of a strong adhesive in the knife-making process.
PVC cement, also known as solvent cement, is designed to weld PVC pipes and fittings together, creating a permanent, waterproof bond. The cure time for PVC cement can vary depending on several factors such as the brand of cement, pipe size, and ambient temperature. Generally, it sets quickly within 15 minutes for handling purposes but requires a longer cure time before subjecting the joint to any pressure. A common guideline is to allow 2 hours for pressures up to 120 PSI and 24 hours for full strength on larger pipes or higher pressure systems. However, it's always best to consult the specific product's instructions as some formulations might have slightly different recommendations. For optimal results, ensure surfaces are clean and dry before application and avoid water pressure for at least the minimum recommended cure time.
