Just wanted to share something I wrote that worked well for me. For those the semi builders out there!
Not sure if anyone has built a semi and wanted to replicate the air hoses that connect from the cab to the trailer. If you have you have you may have seen the pre-made ones that cost about $8-$10 each! That's Crazy!!! Here is a cheap way to make those...
First I took a tube of aluminum that's 1/4" diameter or you can use 5/32" too which is also a common size found at hobby shops. Next is 1mm (The perfect size I believe compared to the oversized premade ones) Plastic Leather cord. This plastic leather cord is easily found in any craft store and is cheap! Its made for jewelry so its pretty limp unlike wire which replicates the sag when its hung. However when heated it holds the coil shape perfectly. So I wrapped it tightly around the tube. I cut slits in the tube to tuck the ends of the wire in so it didn't unravel. Next Take a candle or lighter and heat the tube up. I heated it up till the end of the cord started to barley melt. I quenched it in cold water and unwrapped it. It holds it shape and works perfect. I put cotton swabs in the ends of the tubes so I wouldnt burn my fingers on the hot metal.
