Once more a civilian told me that my machines would not be able to do something. And once again he was wrong, I was right. You can knock down a wall made of wooden bricks with tennis balls.
You just need to throw them hard enough and often enough. The sound of the wall coming down also wakes up the staff at the desk.
The plans are yours for only $10USD. Just saying.
A performance that will bring the house down (if you target a load bearing point.
Know what the difference is between a mechanical engineer and civil engineer?
The wall was actually shuted back quite away and holed several times before it went down. You can still see the curve from the dent.
Mechanical engineers build machines, civil engineers build targets for them. Someone else can rebuild the wall. Not my department.







As a civil in training, I have to say I’d be more impressed if you’d used a real brick wall with some mortar and rebar
For that particular target I’d use Mr Full Sized Treb and a 16lb bowling ball.
Let me know when its ready.
It’s the big round one in Wellington they call the Beehive…. Do you know it?.
I refer you to an earlier request for a “get away truck” for a large trebuchet.
May I suggest more trebuchets would eliminate need for getaway?
You’re going to need a ballista battery for the soft targets that may flee.
Its doable but we’re going to need a bigger crew.
need to be careful there, branding with a tennis ball may constitute assault…… On second thought, how can we up the cyclic rate?.
Tennis balls???? Honking big bolts for this op, I dind;t walk all this way to take prisoners.
