A consensus of opinion from the learned is required.
I am building a half scale 'economy' (Hercules, Jaeger, Sparta etc, etc)
open crank. The engine has the conventional drip feed oiler arrangement
feeding oil through the liner to the piston. The little end bearing/gudgen
pin is oiled via a small hole through the little end of the con rod and its
bearing.
Now the opinions required bit: do I provide a hole in the piston skirt to
allow oil through the skirt to the little end or do I do as the drawings say
and not provide the oil path? I've seen engines with and without oiling
holes through the piston skirts but have no experience of the common
practice on engines of this type (pulling my Amanco or Fairbanks apart to
find out is a last resort you understand).
My take on the matter is to be safer than sorrier and drill the oil path,
does anyone know why this is not a good idea?
What does the team think?
