Caltrops from hell - 3/8", blood groove, beefy enough to take out a semi... Clips from Maximum Overdrive and Convoy employed under 'Fair Use' conditions.
FYI, the rounded point you used is actually less effective for piercing compared to a pyramidal point or an angular cut like a hypodermic needle. It's about surface area. The rounded cone point actually increases surface area. A pyramidal point (like a bodkin) applied pressure at the corners and peels the material out of the way. An angled point like a hypodermic also focuses the pressure to a finer point and reduces the surface area allowing for easier penetration.
I could not honestly say - I never tried making more than what I did for the video and my time frame for that is a bit skewed as I was filming, stopping, trying another camera angle... but if you pre cut enough pieces, grind the points and make some sort of a fixture to bend them, you could knock them out fairly quickly. The welding is really what takes time, trying to keep the pieces from moving as you tack them. Perhaps a twist of bailing wire or some vice grip needlenose pliers would help. Sorry I could not offer more information. Good luck.
@@Autonimous Not to worry, I'm running a fantasy campaign and was wondering how long it would take to secure a doorway using these (party is defending a tomb with a forge)

How long does it take to make *enough caltrops?
