You're all wrong, they're created by the larvea of the Caledonian Rock Beetle. This throwback to the early Credulacene period of prehistory was thought to be extinct until 2003 when similar rocks were discovered in Loch Fyne.

Core samples taken by someone so they could work out if it was really a rock or not ::)

Found on the side of Loch Fyne, on a huge boulder. Initially i wondered if they were drill holes for blasting out but the boulder was large, and not part of a blown up bit, and the edges were very sharp and not weathered of rounded by erosion.
Any ideas what they were?

I see that Magnus Ivanoff has just clocked 143 km or 92 miles per hour in speed trials in Sweden.
Making him the world record holder.
I congratulate him on the achievement but would question that it was done on ice.
If one was to build a dedicated record making craft to operate on ice it would surely be a radically different machine capable of much higher speeds
I would envisage a cabin craft with minimal skirt. pointed front. roll over cage, seat belts , elevators,  etc.
It was a very courageous feat driving a hovercraft at that speed but to be a world record perhaps the operating conditions need defining.

I've just changed Britannia's thrust plugs after 3 years ( checked at each service ).  Still started on the button when changed.

Don't know when i saw a feeler gauge last. Chuck old plugs in the bin replace with new and start engine.  With the BMW K100  thats what you did when it didn't start otherwise no need to change them.

A lot of modern ignition systems use 1 mm (0.040")

What about the one that got dropped on the floor and closed the gap??!!

I copy car mechanics when changing plugs - 1) take plug out of packet 1) screw into engine.
