Simple but brutally effective

I like cheese

I don't know why, but whenever I activate the welders, my ship accelerates incredibly fast, and nothing, not reverse-thrust, or even shutting off the power, or welders, can prevent this. Maybe mine is just bugged, so if anyone knows how to fix this, help would be appreciated. :)

Okay. At one point, I was using this for orbital bombardment, so I just put a camera on the front, and used a ranging shot and eyeballing to compensate for the offset. Still my favorite heavy weapon in Space Engineers.

I just changed the projectile. I didn't add a camera because I can't place it "centered". So the camera would be less precise than just aiming from the cockpit. Just use the welders as "notch and bead sights". I painted the last two welders red for better aiming.

Thanks for the suggestions. I didn't even know I made the last block from heavy armor. I will change this.

I absolutely love this thing. It's incredibly overpowered. Imagine my joy when I realized that the shell only detonates after it pierces the armor. Typically, when I use this, it will blow out the back on the target ship.
Two suggestions for future updates, though.
1: The grinding is the most time consuming part of the firing process, because the piece that is ground is made of heavy armor. I would recommend altering the shell blueprint so that that piece is light armor or something softer.
2: A camera. This thing is great for destroying the enemy from a distance of several kilometers. Unfortunately, there aren't any cameras on the ship, which makes aiming from that kind of distance rather hard. Please add a camera, so that the zoom function can be used to aim from afar.
