Front Spar Cap Width ?
« on: August 25, 2022, 04:14:53 AM »
Hi All, I’ve got CE plans and full size rib template. On page 59 the rear spar caps are listed as 3/4inch which corresponds to the Rib template. The front spar cap is listed as 7/8inch (on page 59) but on the rib template it looks to me as though it’s one inch. Just wondering what others have decided on. ?

Is it possible that there is a 1” space in the rib to allow you to slide it over a 7/8” spar cap?

My wing is not nearby, so this is from memory.

The front spar gets a 1/8” plywood spar web glued to one side of the 7/8” spar making it 1”. The rear spar also gets a 1/8” plywood web making it 7/8” total thickness.

I hope this helps.
