Estes Time Warp Build, #7321, Part 7, Gluing & Filling The Fin Tips

The fin tips and fins had the balsa grain filled and sanded.

Filler/primer and sanding followed.

I used a small diamond file to slightly open up the slots to a friction fit over the fin tabs.

The fin tips are glued on.

There is now gaps around the fin tab joint.

This joint required additional filling,

first more CWF and sanding flat with a block.

The backs of the shield tips are masked and the flat face got a shot of filler/primer and sanding with 400 grit.

Once the fins are glued onto the BT-5 cluster tubes, 

Masking will be tight to separate the black and yellow paint on the inside of the "T" fin.

I sprayed some white undercoat on just the fin tip face and the underside joint.

Notice the root edge is masked off with a narrow strip of tape.
