I recall seeing that design years ago from a guy who built a few different PACs, as well as some other interesting stuff. Always wanted to make one but never did.

Yea I think we culled the design from the internet, the size was a real constraint as it had to fit into a 300mm cube. And not blow up and damage us.

Pretty sure old Shayne Gooch the lecturer was jizzing over that golf ball hurler design about 5 years ago when we had to sit through his class

Yea must have been the lecturer, I remember him.

How gratifying that he is still banging on about it, it is getting on for 20 years now.

Me and a mate built this at Uni as part of the design stuff for a competition, we didn't actually win on the day due to the way the results were calculated but we went twice as far as any other entry and i think they still use it as an example...

Firstly, this is how it works, the basic setup. The red is a bit of 5mm polyurethane, all else is aluminium;

Then you pump air in which seals the barrel and fills the outer. Once it is pressurised you remove the pump, the valve actually has nothing in it so the removal acts as the trigger;

When the valve is removed the pressure on the polyurethane seals the valve/inlet and all the air rushes out, pushing whatever is in the barrel with it.

And as promised, a video of it in action and some fucking dodgy editing for lols.

 

 

I require pics of golf balls being fired through various materials plz. Car doors be good
