I have the capability and expertise to design a ballista able to throw tennis balls pretty through the average brick wall not to mention a captive audience demanding such plans.
So should I actually take cheques or just stick with paypal?
What you were expecting i should agonise over the morality of international weapons sales? What site have you been visiting for the last six years? You may form a queue for the completed plans in the comments section. The new plan is the tennis ball ballista V3.0. The TBall Ballista HP. Yes the HP does stand for same thing as with the Browning 9mm HP.
Use at own risk.
