Big Girtha Build Part 11, Epoxy Fillets

This model is a two engine cluster and epoxy fillets aren't really needed. White glue fillets would be strong enough.
But on a larger model the fillets could be wider.

Before taping up the fins decide on the fillet width.
Taking a tip from Crazy Jim on TRF -
I used a 1/4" dowel to mark the mask lines.
The dowel end is marked with a pencil. The marked dowel is dragged down the root edge.. This makes two even lines one either side of the root edge.

Before laying down the masking tape I added a coat of medium CA over the paper covered fin. I was concerned the paper covering might lift when the tape was removed later on.
The CA was applied over the area where the tape mask will be.

The tape is hard to see in the picture, but the edge is just to the outside of the pencil lines transferred earlier with the dowel.
