After throwing my bottomless cylinder with a gallery, I measured the gallery with calipers and threw a ring that would fit inside. After letting them set under plastic overnight I cut them off the bats, placed the ring inside the cylinder, and squeezed the two, simultaneously into the oval shape. I then put the bottom on the cylinder, I typically throw the bottom slabs on the wheel, but sometimes use a rolled out slab.
Next I used a slab to finish the cover...
I was impressed at how well the covers fit. When I used the slumping inside the cylinder technique it was always problematic because when you flip the lid over it fits on the container in reverse... really a pain if it's a wavy oval.
We are enjoying mah-valous weather in Seagrove today and I am writing this post from out on the porch - 5:30 pm and 70 degrees!
Jeff took the plastic cover off of our little winter garden and everything looks healthy and green.
