Designed to save the tank and player clearly

I really don't think there's a good way to design a frame for the extreme load case of a bad dive. Just isn't practical without something like GRN and even then it's pushing it. Hope the person didn't get hurt too badly.

Not putting a huge hole in the back helps more than you'd think.

I'd like to see some FEA results with the load applied to the ASA. The metal backing that slides in should serve as some local reinforcement (I'd think). A gusset from the bottom back to the front section below the trigger guard would be the best bet (I think... maybe?), but is horribly impractical due to space constraints. I suppose I'm not seeing the load case (other than maybe a rotational load) where the screen would be terrible if done modestly.

[PBSteve]

Rotation is the failure mode. The failure occurs as soon as any lateral force is applied.

I've done the sim, iirc for our geometry it was something like 3-4x stronger without a hole for a screen.

[ironyusa]

I assume the rotation is about the front bar of the frame? Or how did you set the load case?

Unfortunately, it's not related to his paintball work, but for anyone who's interested, Tom Kaye is doing an AMA on reddit: https://www.reddit.com/r/science/com...tom_kaye_here/

I modeled a 68/45 tank and applied the force to the butt 30? off axis to simulate a player falling on it.

That's supposed to say degrees.

man, the older women get, the faster they get. i think i was just used last night. im kind of impressed actually.
