Something I have been working for on and off a year or so.

@Dogwatch is keen on gardening and always figure that I have the shed for car stuff she deserves a shed for garden stuff. Looked at all the mitre 10 cheap shittas and they all looked horrific. Ended up seeing a crowd in TGA called the shed shop selling prefabbed sheds with basic wooden framing. Pulled the trigger and got free delivery through the home show. 

10/10 would trade again very sturdy proper gutters and no rattles. Was awesome they clip wheels in the edges and roll it to where you wish. 

After a bit of exacvation

Had a good pad to put shed on. @Beaver and @GuyWithAviators gave me a hand to make up a base to sit it on to get the shed off the ground, then made up a floor for it.

Lined some walls, made a bench and put a bit of trim round the window and it was ready for paint. All the planks in the shed are planed down old fence palings.

Gave it a lick of paint, popped some shelves in and made up some steel hooks and its good to go. Finally got the aliexpress solar lights in this afternoon shit they go good.

Stoked at how it turned out is a bit fancier then we both anticipated but she does alot of gardening so it gets used alot. Its amazing how much nicer it feels inside with lined painted walls, feels like a proper shed not a cupboard.

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 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.

^very similar to how a nail gun works.  Thanks for sharing.

Hence the short barrel?

better rebuild the super-Nerf 200.
600mm 1/2 copper barrell

12v airhorn solenoid and resivour

12v 4wd-shock compressor

 

jam D6 reo-bar down inside of Nerf bullet for 200m approx distance. will use lead this time, so i can surf-cast hopefully 250-300m

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.
