measure from top of plunger cone or base?

[an angry fix]

quick question...

....the rubber plungers on the needles i have are cone shaped and have a thick cylinder base.

what spot on the plunger should i use as the measuring point?

the tip of the cone? the base of the cylinder closes to the tip of the cone? or the base of the cylinder furthest away from the tip of the cone?

(hopefully that's clear....? i am figuring these needles are pretty common and even if that
is confusing language, people will know what i'm talking about...)

any advice?

The base of the cylinder.

You mean like where to measure for the ml? If so just use the ml line its self. The oil stops at the ml you want don't let the plunger stop before the oil hits right at the ml line itself.
