I've been making some big pots...just because. Check out the sweet Mike Dodd via Batterham knock-off. The tallest is 27", certainly not the biggest I've made but good size. These are all made with the coil and throw method.
Here are 3 even bigger pots I'm working on. These will potentially be the biggest pots I've ever made, maybe 40-48" tall. 25# base + 15 coil so far. They are currently 23-24" wide.
Maybe I'll do a video tomorrow of adding a coil.
