I use Tamiya's Extra Thin cement (green cap). It sets up pretty fast, but gives me the time I need to mold the tracks to the wheels.
I do the long, straight runs on a plastic board with a piece of angle glued to it and let them sit overnight. If I have a long section that needs sag in it, I let it set for about 20 mins to a half hour, then push them down onto the wheels and let them harden.
I do short sections and let them dry wrapped around the sprockets and idlers with rubber bands holding them on.
Once I get all the pieces together, I add individual links between them. Kind of like link and length tracks. It works pretty well.
