Miniature Railway Vacuum Brake Reservoir

Builders can easily find 4-inch underground drainage pipes in their storage areas, usually filled with scraps called dog ends. These leftover parts are perfect for creating specialized components for a vacuum brake reservoir. To assemble these pieces, polypipe cement is applied directly to the end caps and inserted into the pipe, securing them firmly in place. One end of each component features a 20mm hole that allows for various pipe adapters to be fitted. For added durability, nylon or copper pipes are used for the main brake system, while silicone rubber pipes connect the joints together seamlessly. If your printer is not sealing properly, applying two coats of undercoat can help seal the ends, ensuring a secure fit.
