In the world of spuds today I had another hour in the whopper it was very dull today no teachers making me scrape the gum off the bottom of desks just sitting there.
I also worked on my high pressure pump and am almost done i just need to get a couple more things.
I also had a friend email me for advice on a pnumatic cannon(his first)and I told him to come and ask on here. Apolagies to everyone for inviting another n00b .
I did some tests with the new triggered burst disk setup for the KAMG and it works very well and gives some more power to it. But it is kind of annoying having to use two burst disks.
thats about it for me today

Rag...
Are you going to include variables like...humidity, temperature, elevation?

Humidity, temperature, air pressure, elevation... all the real atmospheric variables. Even accounts for the slight thinning of the atmosphere at the higher end of the projectile's flight.
The main algorithm should be solid enough.

I was thinking more like extra features, sort of like mini-tools to bundle with it.

Today...Well ok, yesterday!(always a day late and a dollar short!?)

I got my first copper gun working, now I have a use for the pump I built.

The co-ax I've been working on has passed hydro testing.

I love it when a plan comes together!

What do you think the fps was?

It was frozen, wasn't it?

In the world of spuds today, I haven't really done anything in ages. If I want to get back into it, I'd probably start by building a hi-press. pump so I could make some kind of evil bb gun. Then I could build maybe a hammer-valve or piston valve nail gun/sniper, or an automatic bb gun. I've also been sketching ideas for a pump-action combustion gun, probably to shoot nerf darts (wouldn't have much power.)

In the world of spuds today, I tested my propane powered heater, and discovered it needed quite a bit more flow - the flames are only about 2 feet high, and I need them spaced more closely. Hooking up about 10 tanks and feeding the liquid propane through a 1" hose, along with making a larger main tube and 5 nozzles should help the issue. Unfortunately, this will get rather expensive, and won't actually be completed until June, at best. When it's done, it will serve as a portable campfire and heater for my steam gun. I'm also considering a suplementary air supply to help it burn cleaner.

Today I also experienced a mild explosion involving a paraffin/O₂ hybrid rocket, was nearly poisoned by various vicious gases about three times, came close to melting my camera, used about 250 matches in applications not quite in line with what they were designed for, and managed to accidentally pour 1/2 pound of boiling molten wax on my arm. Gotta love March break

In the world of spuds today I have ran out of apoxy, and become increasingly angry at my piston. I just want it to work!

That is quite a bit of action for one day! I'm glad i don't have to tell you to "Harden the F^&k up"

FUCK ALL PISTON VALVES EVER!
gaaah!
(this is really how I feel on the inside)

Now have a Bex and a lie down, it usually help to leave a project and watch your favourite movie or some such- you will come back with a fresh mind and with any luck you will not fail, again.

In the world of spuds today my crappy soldering on my mini coax decided to blow out (yes I soldered it right and all).
I took the piston, barrel, and pilot assembley from it and made a coax the same size of it out of pvc and am currently waiting for the glue to dry.
It will be my first spare parts gun as I usually buy all the things i need for one progect and rarely anything more the only parts i ever have lying around are small diameter pvc and fittings and that was all I needed for it
god I am loving the new triggered burst disk setup for the KAMG gives me more power and is easier to use.
And that is it.

In the world of spuds today I finally found a QEV with a pressure rating higher the 1 bar XD. Its rated to 10bar, 1/2" porting and costs $80 AU. Im sold.

Keep in mind that the operating pressure will be much higher than the rated pressure wannabie.
