When I assemble indy links, I use the black bottle Testors "regular" glue instead of the liquid. Assemble the links as sets of 5 at a time, then join the sets of 5 together. Gives you enough work time to get the runs together and shape/form them as you need to and also provides a stronger bond...especially if you're dealing with small track links that don't have much contact surface area to begin with.
