You mean like a milo-tin roaster on a frame? This would work with a gas stove but you'd need veins in the chamber for agitation, a whopping big tin for 500g, put up with lots of smoke and chaff, and be able to dump them beans quickly for cooling. A KKTO would be an easier more effective option. By the time you get the tin roaster working you'll be ready for the volume and repeatbility of an upgrade. Why not go straight there?? :thumb:
