Have been getting tired of replacing plastics and not wanting to go glass but have a hard time as a do it yourselfer buying a $300 conical or even a $120 portless SS fermenter when I can get a couple of SS base brew kettles @ $60each and fashioning a seal for them. Anybody tried this? All thoughts and ideas OR actual sealed SS fermentors cheaper than $120 welcome. Looking for 28 to 32 qt. My thought is surgical tubing stuck to the lid should seal it with just a little added weight.
