Very neat 2 spout ladle
Cool link.

Are most aircraft pistons cast or forged???????

Cast ..

I would have guessed "cast" because of the larger temperature coefficient
of forged metal---already have a big enough problem
with the cast pistons, controlling clearance changes with rapid external
temperature changes.

Are they a metal reinforced casting, like a lot of auto pistons?
