Got a 120L barrel off craigslist a few weeks ago. Filled with water and when the staves swelled it became clear that two were severely cracked and causing a couple of significant leaks in the middle of the barrel. I'm no cooper, but have a lot of woodworking skills and tools. Barrel is french oak and I thought relatively new and good shape. I can get quarter sawn french oak locally. Do I have a reasonable chance of copying and bending staves to effect a repair or should I search out a cooper?
