The kettles are cheap ebay aluminum stock pots 60 qt thundergroup. The burners i believe put out 100k btu each
but you cant really run them full bore or you will have about 4 inches of flame up the side of the pots. Any suggestions on false bottoms. Im thinking Jbird but they are kinda pricey.
Thanks for the info on the pots, I am going cheap as well for pots, since I am doing all electric it does not require a good pot, merely a container that can take a temp of boiling.
As far as false bottoms go. I am of the opinion that it does not matter as long as the following 2 items are meet.
1) it can take the weight of the grain bed, so for 15 gallon pots, I would say stainless
2) it covers the entire bottom of the container so you do not get channeling
So, you could make one if you can weld and have a drill press or know someone who does/can. Or measure the bottom and get one that is of a close dimension to the pots dimensions.
