Default Recovery Plan: Split Fin During Build

Hallo! I have a brief story and a question.

Today I cut out fins to a pattern, and was gang-sanding them down to target dimension. And as I'm finishing up the last edge and thinking to myself, "Gee, I think this is actually the first time I've ever made fins from a pattern..."

***crunch***

All three have a crack along the grain ... but it's not all the way through.

I'd really rather not start over. But I also need this model to hold up for at least six flights (Yep, it's my NARTREK Gold project. It's only a wee 18 mm min-dia streamer model, a little like the Quest Pip-Squeak, and I'm only flying it on 1/2A and A motors. The fins are symmetrical trapezoid in shape and 3/32". )

I think I can, first, rub some wood glue into the fractures and dry under weight to lock down the injury. And then, though I wasn't planning to, I think I should paper them.

What say the Voices of Experience? And thanks in advance.
