Estes Skylab #001973, Build, Part 14, Gluing On Fins & Fairings

This is a bit tricky -
Place both the fairing and fin into place. 
Carefully lift off the fairing while still holding the fin in place against the body.

Use a little bit of liquid plastic cement initially so  adjustments can be made if needed.

Check the position with the fairing in place. If all is good, then add some liquid cement down the root edge fin joint. 



I only used a small amount of Beacon Fabri-Tac on the filler tip piece and along the card stock reinforcement root edge. No glue yet on the thin sides.

Side glue fillets follow after the next step.






Use the placement template piece to be sure the fins are straight and centered in the fairing.

Follow with fillets of liquid cement along the fairing sides applied with a brush.
At one time I was concerned that the liquid cement might melt the thin plastic along the fairing sides. As long as you don't overdo it, it works well as a fillet.
