Where there is a will....there's a way

I needed to drill three (3) holes in a copper end cap in the shape of a triangle on a round scribed line.
I don't have the smarts to work out mathematically where those three marks should be.
So after some thought I Googled some drawings till I found what I needed and printed out it out (had to print a few changing the size of the image
till I got it exactly to fit in the scribed circle).
Once stuck down I was able to centre punch....worked well for me!

Equal Lateral Triangle = All three sides the same length, is also an Equal Angular Triangle = All interior angles are the same at 60 Degrees!

Looks suspiciously like there are going to be three flue tubes in your next Rat Boiler?!?!

Suspicion correct Columbo
