Next came the “bowling alley” section of the browling alley: the pins, pinsetter and ball return mechanism. To build the pins, we visited a nearby hardwood slash pile left behind from a logging operation, grabbing small, straight trunks that were between two to three inches in diameter. Using a borrowed bowling pin as a reference, we cut ten of these to 15.75 inches or 400 mm tall. At the top of each pin, we just took a little eye hook and drilled it in.
