If you take up adjacent floorboards inside your house, is the void below

Is that not going to need a 1.22m long drill bit?


Yup, and will require mucho upheaval of furniture, carpet, floorboards
and damage to passing drains, possibly introduce a new course for water
to ingress, and cause worry as to where the cat has gone after the works.

Not one of my greatest ideas...


Better than one of my apprentices idea of drilling though a 1.22m wall
with a 1m long drill bit.

"Drill from both sides and hope that the 22mm holes meet in the middle".


Perhaps he'd seen how the channel tunnel was made ;-)


Maybe.

But I know the bloke that managed to get Dodworth and Redbrook
collieries coal drilling machines to meet up only 2 feet apart in the
early 1970s
