This will help you so much.
It takes you through all the steps that are needed to build the relays up.

Basically...
Solder relay to veroboard
Take a spare cable with a plug on one end
Strip the black stuff from the outside of the cable
Cut the negative cable short and strip it
Strip both ends of the bit you cut off above
SURFACE MOUNT using a lot of solder to the contact on the relay
This is to make sure the veroboard doesn't have to carry 243V AC, only the solder contacts have to carry the V's.
Then solder in the two coil connections
I used multicore wire from the relay so I used a terminal block to convert it to single core.
