I'm thinking about building another UDS except this time I thought about turning it over and using the lid as a removable bottom for easy cleaning. I will have to cut the bottom out but was thinking of using a kettle lid. Will removing the bottom weaken the drum wall? I believe the lip on the bottom is rolled on so I'm hoping it would still stay attached for rigidity. If it's going to come off and make it really flimsy I probably wont do it. Thanks.
