"In the world of spuds today"

I'll be quite short on time, but could give that a try, which one though ?
Plasterboard, pine, water jugs ?

[SpudFarm]

Plaster is what is most comonly used so give that a try.

ITWOST, I attempted a 15mm ball valve based launcher.

Epic fail.

I can't get epoxy to work no matter what.

I'm going to get a 15mm endcap tapped, so I can use the threaded schrader I've got.

Current count of working launchers, 0

Number of fails, 5

Sorry for the vent, cheapo epoxy annoys me.

[Crna Legija]

whats happing with your epoxy, did you use the right ratio and mix it good also you have to rough up the part you are epoxying

[Zeus]

I just think I had shite epoxy, so I'll just get some JB.

I know that stuff works, anything is better than $2 shop epoxy.

[Crna Legija]

i used 2 dollar epoxy for my 700psi tank. and it only lost 130psi over night

Thats, pretty good. You reminded me to do the same test. My gauge is in MPa, inconvenient. Yes.

Don't lengthen the ignition leads. Just make sure you're wearing your safety glasses

ITWOST, I have 1000 0.18g or something airsoft BB's coming from the UK, like $3-4 delivered..

@-_-

damn I wish it was a psi/bar gauge not kpa

10bar = 1000 kPa
20bar = 2000 kPa and so on
just cross out two zeros and you've got bars

[Crna Legija]

i know3 but bars sound better than kpa, like iv never seen kpa use in the real world.

It is used in the real world...Scientific pressure measurements tend to be in pascals..

[Ragnarok]

I know but bars sound better than kpa, like I've never seen kpa used in the real world.

Then you've been looking in the wrong places. Pascals, Kilopascals and Megapascals are the official scientific standard!
For comparison, bar aren't actually SI units. Although of course, they are defined in terms of SI units and can therefore be used alongside them very easily.

Either way, you're complaining about one of the simplest conversions possible...

[Technician1002]

Most of the stuff I work with is in Kilopascals or Torr and Militorr.

Pascals are used for pressure and Torr is used for partial pressure (vacuum) measured as absolute pressure. When working with turbo molecular pumps and cryopumps, pressures well below 1 militorr is common. Most stuff we work with is not high pressure. Most stuff is regulated well below 10 Kpa for our work.

A very few of our gauges read in both Kpa and PSI. I wish more of them did.

Somehow, I managed to borrow an HD camera for a short while today - so I figured I'd show you one of the tests I'm doing on what's being called HEAL 1.5 - the completed parts of HEAL 2, bolted to enough parts of HEAL 1 to get it working (so, still stuck with the old breech action, unfortunately)

Here we have a 25 bar test - barely over half the launcher's final power.

Unfortunately, although the visuals are decent enough, like any camera I've thus far seen, the sound in the video really doesn't do the real thing justice.
