This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

Thermal image of cutting a metal bar with a hacksaw (media.piefed.social)

The bar is clamped in a metal vise, so the vise is very slightly heated and that side of the bar is much cooler.

hm, having hacksawed lots of round stock over the years, that's a lot less heat than we expected! then again the hacksaw blades we use are frequently thrashed hehe :)
