I have a couple of old barrels and while recently checking them out,
noticed that when looking through the bung hole, I could see "space"
between the staves opposite the hole.
My wife has been thinking about "appropriating" one for use as a rain
barrel and I wondered if cutting out the head and filling with water
would "swell" the staves to their original (or close to) condition.
Is it possible to "restore" the barrels to good condition i.e. water tight
capable or are they pretty much "ruined" and suitable for display purposes
