Rebore

If you want to keep using that rifle, you'll have to rebore the barrel.

The cylinders of your engine are so worn the rings don't seal any more; you have to have it rebored to stop it from burning oil.

Every major bridge, and many of the smaller ones, have been rebuilt, tunnels have been rebored, and long sections of track realigned.

However, any increase in capacity is useful and, if an engine is worn and needs a rebore, it's worth considering boring to a near maximum size rather than simply having it bored to the next oversize.

And on that day the Lord rebore me and I was reborn.
