For a long time now I been try to workout the name of cut out holes they used in airplane and ship building (the pink ring -below) to cut down on the weight from plate. Does anyone know that these are call, the cut outs?

Hi Simon, in some plans I have for WWII aircraft they are called "cut-outs", not very original or sexy I know!  I have also heard them unoffically referred to as "mouse holes".

     Also known simply as 'lightening holes"...

NZSnowman:
Thanks, Bill & Greif.

I think now I have heard before 'Lightening holes'  ;D :D

Rokket:
A bit late, but Google helps me concur:

"Maritime & Shipping
LIGHTENING HOLES
A hole cut in a plate to make it lighter and yet not reduce its strength. Sometimes large enough to be called a manhole. "

Als numerous ix and references inc aircraft. Col, never thought about name!
