Nice stand I'm thinking about making one similar but adding some casters. What size did you make it, what type or oak did you use looks like 1x 12"? & 1x4"
When I make barrel stands, I always make the stand as wide and as deep as the head hoop diameter. IIRC, this one has a head hoop diameter of 18", so the stand was 18" wide and 18" deep. The lumber is premium red oak, 1x10 and 1x4. When cutting out the curves, a radius that is around 1" smaller than the barrel head radius is used, that way the barrel always rests on the haunches and doesn't rock.
