The fins were tacked in place with white glue.
Before the fillets were added, the pencil lines were erased with a white eraser. I didn't want to apply glue over the pencil lines and have them show up under the paint.
The Semroc Goblin re-issue kit has a 3/16" diameter x 3" long launch lug.
The original Estes kit had a LL-2A launch lug. The LL-2A lug was 1/8" diameter x 1 1/4" long.
To build it like my original Goblin, the single LL2A lug was cut in two.
The lower lug is centered between two fins and flush with the low end of the body. The upper lug is glued 1 3/4" from the top of the body tube.
I'd thought about using epoxy for the fin fillets
I ended up using white glue.
These pictured fillets were built up in five coats.
You can actually get a little fillet buildup with white glue, it just takes a lot of extra coats.
Every succeeding coat dries faster than the one before it.
