I've been looking to upgrade from my 15L Aluminium Pot I use on the stove to a Stainless Steel kettle I can do full boils in (for 20-25 Litre batches). I'm trying to be reasonably thrifty with this and have found some 38L Stainless Steel stock pots on eBay going for a good price. However I noticed these are only 1mm thick. Will that be thick enough?
I am planning to install an element into the kettle itself (with weldless fittings) rather than heat it directly on the stovetop (I'm currently in an apartment with no outdoor space for a gas burner). I'll also most likely fit a ball-valve. Will the thickness matter when drilling holes and adding weldless fittings?
