When selecting PVC pipe for Nerf darts, the most commonly recommended diameter is 1/2 inch (about 12.7mm) Schedule 40 PVC pipe, as it closely matches the diameter of most standard Nerf darts, providing a snug fit that is ideal for blasters modified to shoot through PVC barrels. However, it's important to note that dart sizes can vary slightly between different Nerf lines or third-party manufacturers, so some experimentation might be necessary. Additionally, the wall thickness of the PVC pipe can affect the fit; Schedule 40 strikes a good balance between durability and internal diameter. For those looking into homemade Nerf guns or modifications, using 1/2 inch PVC allows for an easily accessible, cost-effective, and versatile option.
An all-resin pool refers to a type of above-ground swimming pool constructed mostly or entirely from resin, a durable synthetic polymer. Unlike steel or aluminum pools, resin pools are highly resistant to corrosion and oxidation, making them an excellent choice for longevity and maintenance, especially in areas with salty air or harsh weather conditions. The materials used allow for various shapes and sizes, providing flexibility in design. Moreover, resin pools are known for their thermal resistance, which can help in maintaining water temperatures. They handle the effects of UV radiation better than other materials, preventing fading and cracking over time. While typically more expensive upfront, their durability and lower maintenance needs can make them a cost-effective option in the long run.
Storing resin mixed with powder requires attention to prevent the mixture from hardening prematurely. Firstly, ensure the resin-powder mix is in an airtight container to avoid exposure to moisture and air, which can trigger the curing process. Use containers made of polypropylene or polyethylene, as these materials do not react with resin. Keep the mixture in a cool, dry place, away from direct sunlight and heat sources, to maintain its workability. Label the container with the date of mixing and the type of resin and powder used, as different mixtures may have varying shelf lives. Regularly check the consistency of the stored mixture; if it starts to thicken or cure, it might no longer be usable for your projects.
