You’re gonna shake your heads but i cant help it, gotta post this. I was hotwiring a block today and i broke two guitar strings in a short amount of time and had only made it about a foot and a half into the block. I helped my brother hotwiring and i think his guitar string was copper core, didnt break. The last time i did it myself i just used some rebar tie wire and although not tension wire it worked ok, but kind of a fat cut, and a couple drippy spots occurred. So the second string broke and suddenly i remembered my dad cleanly slicing a six inch piece of pvc pipe in half with a piece of mason twine. Went over to the shelf and grabbed some, held it between my hands, got it into the cut, and started flossing. Within seconds it felt sticky. The friction was starting to melt the foam. I kept going, sawing like a madman for thirty seconds and then taking a short break in between each go. It took me ten minutes to cut the other six and a half feet this way, and if someone was helping me like how they used to cut trees before chainsaws, it wouldve been five minutes to do the whole cut on this twelve inch wide block. It would take two people less than ten minutes to cut eight feet on a 24" block. I used some yellow braided eighth inch stuff, but i’m sure the pink or neon yellow would work the same. There was no smoke so it wasnt like the effect of rubbing two sticks together to make a fire…but what came out of the cut was some half melted crumblies. Im gonna abandon this as soon as i get the right type of wire for my hotwire setup, but i plan to cut the other half of this blank the same way and i will never forget that it works. Very minimal ridges. After the apocolypse when survivors shape their boards with rough stones, power tools will be useless, but they could still cut true to their rocker templates with a piece of string and some elbow grease. I don’t want to see any ‘go green’ yobbos posting their fancy hotwire setup over on that thread, now…no excuse for that any more. I’ll try pics, hope they show up
