Spar fitting locations
« on: August 28, 2017, 04:42:15 PM »
I have a question concerning the spar fittings on a DE.
The front and rear are both to be located with the mounting hole 1" up from the bottom and 1" in from the inside edge.
It occurred to me that the rear spar actually sits inside the rib, while the front spar sits against the rib.
This locates the rear spar fitting 1 1/4" from the bottom of the wing. This is because the rear spar will be sitting on top of rib bottom, which is a 1/4" spruce strip.
Is this what is expected, or should it be located 1" from the bottom of the wing?

Thanks for the responses.
MrG, nice photos!
Leonard, you mean the 1 1/4" dimension is correct for the rear?

This is just for future reference for questions that maybe can be better answered. 

"from the bottom" What bottom are you referring to? 
what "inside edge" are you referring to?

It might be well to explain what you mean by sitting "inside the rib vs against the rib..

I am sorry, but today after a day of answers to  questions that completely were dependent on what was being called "what"... with nothing being standard.. I felt that to answer in detail, I needed "details" for such answers.
 
I suppose that sounds cloudy... sorry but seems to be the only way at times.

While the first link does work this is the same link expanded a bit more.

The metal work, as well as some great wood jigs (set-ups) are shown in the photos.   The metal work in my mind is exceptional and top notch for this craft.
