This may be an obvious thing to most people on here; however, i felt it was worth mentioning for those out there who may not know.
If you intend to build a cooking grate for your heater… …DO NOT use galvanized metals!!! If you are unsure, ask. Metals and alloys treated with chemicals release various, sometimes toxic, fumes when heated and could incapacitate or possibly lead to serious injury/death; especially, in close quarters such as an ice shanty etc…
I think this is a great idea and plan to build one for my self. That is unless i find a nice vendor who sells them for $25. I would love to see some pics of peoples setups. I too love seeing mods and love the ice fishing world for all the creative solutions.
