Need some help soldering Binding posts.


I need to replace my posts on my speakers.I've an excellent soldering station
and will be using cardas solder.
All binding posts have a hole what is its function?
When applying the solder I've noticed I must use more and apply over a greater area,Is this correct?
Is it ok to use flux on the post and cable then solder?
Any advice.

The Cardas hole makes it tricky. It does not take much solder and you need to see the strands of wire that have been tinned in a small trough of solder. I've done it 2 ways,take off binding post copper nuts, put drop of solder in front of hole and another small drop across hole towards the cavity. I've done it between 700 and 850 degrees. Soon as solder starts to melt hit the tinned wire for split second then then put it all together fast.  Other way is to clip off or cut(Dremel) the hole and your left with cavity with easy access. When you melt solder is more a timed thing than a visual thing. Can't see solder it just disappears and bubble gums. If you can slide washer on wire it can also give access to more metal to heat up, I never did it that way.
