Stay frosty, my friend.
I take some oak blocks the right size to fit clamp (3x3x2) for mine, pick a forstner bit the diameter of the barrel, drill it out, split the block down the center of the hole with a saw, apply an ample coat of rosin powder on inside of blocks, clamp and remove the barrel, no marks and cleans off with a wipe of WD-40,
