Not a bodge as such but a repair to an insignificant issue that caused more damage than the issue it was trying to repair!
Rear lower crankcase corner and a 'Tinker's Patch' has been made in copper and fitted with a series of 2BA screws. Behind the patch is a small area of corrosion to the casting where, perhaps, it had been affected by water. No associated damage on the inside of the crankcase so the defect was only cosmetic. However, the drillings for the 2BA screws had produced a series of 10 small holes through the side of the case!! Given that this was the only issue with an otherwise excellent vintage, sand cast, crankcase a repair was required comprising the sealing of the holes with suitable tight fitting aluminium rivets (thanks for the suggestion and the rivets, Duncan) with a dab of stud lock on each as belt and braces.
