You think it's bad here? Try getting involved in making pulsejets :P "the death of the forum" has been ongoing for a while, with several technologies vying to take its place. All sorts of gamifyng and the like, and it pulls users from forums with glitz and pizzaz, but the problem as I see it is that...

About the only way you're really going to get an idea of muzzle energy is to run it through a chronograph, or if you don't have access to one, shoot into a ballistic pendulum. The latter is very easy to set up; with a mobile phone as camera ad some calculations you can get some very accurate results...

Fuck off, spamcunt.

Nice machine, and nice result.

For hydrotesting, cheap hand actuated grease guns generally go up to about 400 bar, used one for some hydroforming experiments a while back. The hardest bit is fittings, and managing to get a gauge in circuit.

Sometimes building tools and jigs is half the fun :D

And the other half is doing it again when you realise you've buggered something up :)

At an average walking speed, it'll probably take you between 3 and five minutes, longer if it's uphill. The limiting factor is going to be how heavy the cannon is, but you can probably mitigate that by fitting it with wheels, at that point it's all down to terrain. Sensible answer, it depends, among...

A spud gun is not an airsoft gun, so I'd say it's extremely unlikely. IANAL, obviously, but given the way things in the UK are going, a spud gun is more likely to get classified by the lads in the penis hats as being an improvised firearm, the sort of thing that could quite feasibly get you 5 years ...

Well that was a load of word salad conspiracy bollocks. I feel dumber from having merely skimmed it. Thanks a bunch.

[edit] This post was made in reply to some absolute crap that jrrdw just removed, and not in reply to what's now visible up above.

Back in the day, we had little diesel aero engines that ran on a mix of ether and castor oil. A good source for ether might be one of those easy-start cans.

OK, you're young, and you're enthusiastic. I'm old, and cynical, and jaded. Here's some advice. This is what's known as a "forum", and it's not even a particularly active one, even by 2024 standards. It's not instatwatbotik. There aren't 50 trillion twunts watching it for the latest news, poised rea...

OK, I'm gonna hit you again, perhaps less gently. Quinn. What you are doing is not polite, and at best is creating cleanup work for the moderators. Generally speaking, forums have their own rules, the ones for this one are found here , but there's a more general set of rules that are assumed to be g...

The website does not work because the entire xinventions site is dead. the page, including photos, is available through the wayback machine, but as they were selling plans, and the people who ran xinventions are not the people you are talking to here , you're unlikely to get the plans by asking here.

nice gun and great work How, in the name of all that's holy, could you possibly know that? The photos are dead, the videos are private, and apart from one post in 2019 the whole thing hasn't been touched since you were literally in diapers. SpudFarm themselves haven't posted since 2017. Your contin...

Believe me, you really don't want me to join.
