on Mondays and Wednesdays
“A Treb” computer

I spent on materials
Holes must be bored perfectly level, so arm is plumb.
Triple 2X4 construction
Cotter Pins Hold Arm from moving horizontally
More cotter pins so axle doesn’t come off supports
Screwing it together is easier
Cheap & real HEAVY
Launch trebuchet from a safe distance
Heavy duty construction meant a safe launch
About 100 lbs. of force
Slip metal ring attached to the arm over the trigger rod.
Stick a screwdriver shaft through eyebolts
Pull screwdriver out with an attached string
