Hi Dwaine,
Here's what I do when I attach the railings on my ship. First I measure the lenght I need by dry fitting a section of railing. Afterward I cut, bend and adjust the railing and I dry fit a lot to assure a good fit. Then I apply a tiny amout of CA glue every 3 or 4 stanchion then I attach in place. Once the railing is in place I run a small bead of CA glue along the inner side of the railing to solidify it. I always try to work with the smallest lenght of railing possible because it is easier than trying to tackle a very long rail with bends and curves in it.
Go slowly and in small sections and everything should be fine!
Happy modelling!
