I need to add about 1/4" strip to the edge of my newly purchased

Can anyone see a problem if I used fir instead of spruce for this
strip? Fir is more easily available locally - Mike

Mike?

You need to add a 1/4" strip - that is going to be mostly beveled off?

This is a trick question, right?

What would it matter what you used for this??

Richard - thanks for the reply. I am concerned about two things;
because pine (for example) has a different density than spruce, they
might react differently to humidity or temp change and affect the
straightness of the spar. Second; some A&P looking at it and reject
the repair.

Granted, the amount is so small, I'm probably worried about nothing,
but being part of the USG, I"ve seen minor things become bent way out
of shape just because someone got their teeth into it. - Mike

Do you think I'm being unreasonable?

Probably, but that's ok.

Like Jerry said, glue it on. (With a good epoxy - I'd use T-88)
The strip is so small it shouldn't cause any problems.
