Estes Odyssey #7235 Build, Part 18, Wing Detail Guns

The small rings (Parts R, S, T,U & V) were a bit loose around the supplied dowel. 

Some glue was set in the center hole to narrow the diameter. Let the glue dry before fitting on the dowel. 

I applied a small ring of glue around the ring position and slid the ring into the glue.

The right side picture shows the careful glue applications on the bottom of the S ring. Remove any glue that gets into the slots. Keep glue off the flat faces.

Here's the second T ring slid into the small ring of glue already on the dowel.

Hit the glue and turn the ring to even out the fillet. 

Doing it this way I kept things clean with most of the glue underneath. Sometimes applying additional fillets on parts this small leads to a messy final finish.

After the S, T, U & V rings were in place and the glue dried, The Y pieces are glued in the slots.

Note the small line of glue on the "root edge" of the Y piece. More glue was applied underneath the ring keeping the visible top joints clean.
