Homebrew store no longer carries natural cork carboy sized corks, so I headed to Michaels craft shop and bought two of the 1.56" x 1.5" corks. A mini hacksaw, 100 and 180 grit sandpaper, and a bead reamer to make the hole up the middle. I rounded the sharp edges after this photo and picked out the grit that was embedded in the surface. New float ready to coat in 45 minutes. 30mm x 30mm same as the old.
