I love all the under bonnet drilling. Am doing up a trailer to carry a friend's Austin 7 to his first event at Goodwood this Saturday - anyone passing? Its a Brighton club sprint. I put a winch on with a new bracket to raise it for clearance and couldn't resist getting out the hole saws and drills "just because".
A friend sent me this a while back - still sitting in my inbox for a "proper look sometime". The concept is "drillium" as an alternative to making from "unobtainium".
