Step 7Foot Pump
The pump is made from a marine (outboard motor) fuel line primer squeeze bulb. The hose and bulb (with integral check valve) was purchased as an assembly from a sporting good / hardware store that sells marine supplies for outboard motors.
The pedal assembly was made from scrap wood, a door hinge, wood dowels, and a foam rubber toy ball.
The dowels (glued into holes in the wood base) allow the bulb to move up and down freely when pumped. The open top of the dowels make for easy installation and removal of the bulb for storage.
The foam rubber ball prevents damage to the rubber squeeze bulb.
The ball was cut in half and epoxied into a recess on the underside of the pedal. The recess was cut with a hole saw drill bit and then the material inside the hole saw cut was chiseled out.
