Building a Mechanical Hand Pump: DIY Project

💡The mechanical hand pump can be used as a backup pump and for pressure testing boilers.

🔧Various components are needed for the hand pump, including the plug, cone-shaped pickup, valve seat, piston, and pump handle.

🛠️Quinn demonstrates the step-by-step process of creating each component using tools such as a lathe and mill.

⚙️The pump handle is designed with a ball end for a comfortable grip and aesthetic appeal.

🚂The hand pump is specifically designed for use in a water tender on a Pennsylvania A3 switcher locomotive.

What is the purpose of the mechanical hand pump?
