To attach PVC to copper pipe, you'll need to use a special adapter known as a copper-to-PVC adapter. First, ensure the copper pipe is clean and free of any debris. If the copper pipe has been previously used, cut off any damaged or irregular edges and sand the end to smooth any burrs. Similarly, prepare the PVC pipe by cutting it to the necessary length and ensuring a smooth edge. Apply flux around the outside of the copper pipe and inside the fitting of the adapter, then solder the copper side of the adapter to the copper pipe, using a torch. Once the copper side is cooled and secured, apply PVC primer and PVC cement to the outside of the PVC pipe and the inside of the PVC side of the adapter. Quickly join the PVC pipe to the adapter, twisting slightly to ensure an even distribution of the cement. Hold in place for a few seconds to secure the bond. This process creates a durable and secure connection between copper and PVC pipes.
Preserving flowers in epoxy is a beautiful way to keep them intact for years. First, choose flowers that are dry and free of moisture to prevent clouding in the resin. You can air dry them or use a desiccant like silica gel. Next, prepare your epoxy resin by mixing the resin and hardener according to the manufacturer's instructions. To begin, pour a thin layer of epoxy into your mold and let it partially cure. Place your flower on this layer, then carefully pour the remaining epoxy over it, ensuring the flower is fully covered and there are no air bubbles. Allow it to cure fully, which can take 24-72 hours, before removing it from the mold. It's crucial to work in a well-ventilated area and wear protective gear to avoid inhaling fumes. This process immortalizes the flower in a clear, durable medium, perfect for jewelry, paperweights, or decorative items.
Setting twist into yarn is a crucial step in the yarn-making process, ensuring the fibers hold together and perform well during weaving or knitting. First, gather your materials: roving (prepped fibers), a spindle or spinning wheel, and a niddy noddy (optional). Begin by attaching the end of your roving to the spindle or spinning wheel and drafting (pulling) out a length of fiber. As you spin, twist is introduced; more twist makes a stronger yarn but can affect flexibility. For a balanced yarn, after spinning, use the park and draft method or ply the yarn back on itself (Navajo plying) or with another single yarn. Balance the yarn by gently tugging on each end until it stops twisting back on itself. Finally, wind the yarn into a skein using a niddy noddy, and secure the ends. Soaking and then hanging the skein allows the twist to settle, securing the fibers.
