    Fuck yeah rebar caltrops. Are these hard to make? Just wondering how much effort someone put into making these. Seems hard to pull off.

      Actually it looks pretty easy. Rebar is usually pretty easy to bend, especially if you have a blowtorch, which you would need to weld them together. A little heat to fuck the tempering and you can bend it with a vice and a hammer.

        You don’t even need to heat it. #5 or 6 (1/2 - 5/8 inch)rebar fabricated in the manner shown in this pictures would fuck up a tire good.

        You can easily bend it 45 degrees with a good vice and piece of pipe.

          Oh fuck I forgot about the pipe trick, and that's what we use at work to tighten this big ass vice with a spoked wheel. Instant leverage boost, I love it!

            You don’t even really need a vice or pipe.

            My concrete kids forgot to bring fucking every tool to a site. I just lifted a skid steer bucket off the the ground, put the rebar in between the ground/bucket and used the length of rebar as leverage.

            You would waste a bunch of material building them this way. But that shit is pretty much free at every construction site after hours.

          Probably not. A diagonal cut would be all the "sharpening" that would be necessary, but even that it might not actually be necessary. The weight of the vehicle is probably enough to pop the tire under the stress.
