I use accordion covers on mine. I was fortunate that a machine at work needed new ones and these fit perfect. Lathe is a 14x40. McMaster Carr does sell them in larger sizes and they are pricey.
Most mills do not make the blue chips that I see coming off my lathe, thick and wide and smoking hot; blue is 600 deg.+F.I used to install those same covers in Mills, they hold up quite well.
