I desingned a track, and started out with plywoood as a base and apinted it gray. Then on to the styrofoam, i drew the barrieers out that i would use on top of the plywood, but its impossible to cut! Its extremely messy and i am using a small blade, it is a very tough styrofoam and has a smooth compressed surface. What should i use to cut it? 🙁 🙁
Welcome to the forums. I encountered the same nightmare with my first foam cutting exercise. My workaround was a 32TPI (Teeth per inch) hacksaw blade.
However, having seen my messy results, other members on ausmicro.com advised that there is actually a product called a “Hot Wire Foam Cutter” available (about USD10.00). It cuts though the stuff like the proverbial hot knife through butter!
Good news for people in Australia! Someone from Dymocks (the bookstore) was reading this thread and has emailed me. Apparently their big George Street (Sydney) store (the one with all of the art/craft stuff next door to Grace Bros) has hot wire polystyrene cutters in stock. Price is AUD26.90ea (approx USD13.00)and it can cut foam up to 4 inches thick
