This is a photo, taken at my local Toyota dealer, showing miniature mechanics working on the engine on my car:

Didn't realize they were using a straight eight these days.

You wouldn't be carrying your vernier calipers in the back pocket then.

Just think our Grandfathers used to make things like that and now we can't even make our own bloody railway engines.
Hang you heads

A work colleague (from the motor industry) sat on a committee that decided the 'standards' for nuts and bolts (including the dimensions of the heads of bolts and nuts).

He said that on one occasion, a previously silent participant interjected that the proposal was unacceptable as the bolts "Wouldn't be climbable."

After some confusion as to his meaning, it was explained that his company built very large structures, and the maintenance engineers relied on the heads of the bolts as footholds when they needed to climb the structure.

Bloke in green asks:

"Are you some kind of crank?

Bloke down the ladder says: You bet I've got the keys to the ignition in my pocket!

It's awe-inspiring to think that these things are rated at the equivalent of several thousand HP per cylinder!

I suppose if the principle is proven & you can scale the design, then the power is a function of how much bang juice you can pour down the cylinder in one go. Very impressive to see all the same.

Spare a thought for the poor buggers that have to repair ships engines when they suffer serious internal damage!

Most ships carry at least one spare piston, and these are often replaced, in-situ, at sea. However, serious internal engine damage, such as a damaged crankshaft, is a real headache... and in the case of the very large engines, this can result in the ship being scrapped.
When you have an engine bedplate weighing several hundred tonnes, it just can't be fixed anywhere... :suspect:
