Holy mother! I very VERY much enjoyed those videos of such heavy weight destruction. Impressive to the max. Thank you for your time in putting these videos together. I know it takes some effort. Rock explosion video FTW!

Thanks Moonbogg! I try to keep my videos simple but reasonably detailed.
I imagaine I can do some more shots tomorrow. It kind of starts being hard to find targets
Edit:
I found some targets, not very good ones but I plan on shooting the chair again. Perhaps with different ammo.
The motor had no internals and I have been trying to crack it's casing with a hammer for a very long time to melt the aluminum.
Should have thought of using the cannon
Thats some insane power right there. Its kind of morbid, but I am forced to immagine what it might be like to get hit square in the belly by that thing (is that against the rules to say?)

Looks like SpudFarm needs to acquire a rather large quantity of ballistics gel.
Moonbogg: I would not like to get hit in the belly with this Would drain your lunch in an instant.
Spudblaster: A few tons of ballistics gel would certainly make up for a shocking shot. I can imagine a 600g slug tumbling through meters of gelatine, creating huge cavities.
Hmm, interesting! Anything that can be made practically and simple to give an idea of what it could do to flesh?
One could simply assume it is simply Death-On-A-Stick, but that's no fun.
Box-O-Truth?
Water usually gives a decent approximation. A bullet will go through about half as much flesh as water. So you need an underwater video camera, and the nearest LAKE.
DO NOT have anyone's head (or body, really) in the water when you fire. Keep in mind that you may kill fish with the shock-wave.
Does anyone know numbers of stress/strain for flesh? If so, I could try it in ALGOR. It might not work so well though. When I simulated a dart piercing steel, it crashed before the dart de-accelerated at all. The tip made it to the other side with full velocity (obviously inaccurate)
I will probably do one more shot today if I can figure out what to shoot.
Edit:
DYI have put a thought into my head. I wan't to take it to 20x this summer.
I don't really know if it is safe at those mixes but it was pressure tested to 180bar..
The performance I would get from it would be astounding! With 1.5kg slugs at 299m/s I will reach for 67.000joules of muzzle energy
The worry is that it fails and blasts a nice hole through my roof. So extensive testing with a test chamber will be done first.
dude I love these videos! Don't stop until your gun ceases lol.
Your gun and the projectiles your firing inspired me to incorporate recoil absorption into my gun. And like you, I plan on taking it above 10X, though only to 12-15X lol.
I got kind of tired of waiting for the new union (Sorry MC:D) so I reasembled the cannon with the old one and took a shot at 25l of water in a fuel can.
The velocity was lower then expected but I think it is because the burst disk slips out of the union on one side and resticts flow.
I am also thinking about getting a new manometer for the fuel meter since this one is getting quite worn out now.
Very nice. I've seen many videos demonstrating hydraulic shock, but certainly nothing of that scale. Impressive stuff.

That is quite likely. I had a similar issue with unmodified hardware store unions on my smaller hybrid designs. If the disk managed to seal effectively enough to allow the launcher to be fired, it would often partially slip out of the union, lodging in the barrel port and heavily constricting flow.
I achieved a solution by grinding down the tapered surface on the female component of the assembly. As your McMaster union uses flat mating surfaces, it should solve this issue as well.
