I wonder how hard it would be for one of you CAD guys to make up a real set of drawings, showing every part with actual angles and dimensions? Sure would simplify the build, and maybe more potential builders would start and finish an Eagle

Is there anything about the current drawings that prevent a motivated builder from completing an Eagle?

None what soever, if in fact one is motivated as you say. You in fact made several changes to your build, wouldn't it be nice if a new builder had all that information in front of them in black and white? the Wright brothers didn't have so much as a sketch, but they were no doubt motivated . Just look at how many questions there have been just about the thickness of the wing/gear brackets. I would have liked to have seen a mechanical drawing of both your design for that bracket as well as Leonard's.
There are builders that just love to build, there are builders that just want a plane to fly, the ones that are a combination of the other two, and finally l the ones that start and never finish. The latter being the largest group. I read where only one in ten that order aircraft plans ever start the project, and out of that group only one in ten finish and fly the plane. I'm all for anything that would help increase the number of planes started and finished and flown. Just thought, I personally spent my adult life working with detailed drawings, would have liked to have had a set to build from. some of the CAD drawings I have seen are absolutely great, sure would have helped me on my first try had I had them to study. There were many changes I had to make when I built my DE because there were some parts that didn't quite work, and as a newbie builder , if I was not motivated would have been enough for me to just quit. something would have to be worked out for Leonard's blessing, but IMHO, a detailed set of drawings would certainly be a plus.

You presented interesting points, some of which I agree with.
There is a reason why I have refused to offer dimensions and parts lists for the mods I made to my Eagle (in spite of numerous requests). The modifications to my aircraft were made only after my mission profile, builder skills, and risk management were analyzed. The results I came up with are not appropriate for all builders and I have no intention of supplanting Leonard as the official source of build info for his plane, or suggesting "authorized" changes. Builder beware if you consider cloning anything on my plane, my changes are prototypical in the strictest sense.
The material thickness for the strut brackets is clearly called out on the plans.
And this will no doubt offend some...but I am sorta old-school in holding the opinion that someone who isn't motivated to study Leonard's plans enough to figure things out really shouldn't be building a plans-built aircraft. Building something as complex as even a simple Eagle is not for those who have issues with self-motivation or solving problems. Problem solving and THINKING is the motivation and reward I find in building something like an aircraft. Not everyone is ready to exert the necessary effort, and a kit-built plane or other project will probably be a better fit for them.
Yes, Scott's CAD renderings are great, but present an awkward situation for his working relationship with Leonard. 'Nuff said.
I think we would all agree the best resource we have is this forum where questions can be answered and new ideas bounced around for discussion. Over the past three years I haven't seen any questions presented that couldn't be addressed by members on the forum....well...maybe not when it comes to the ultimate prop. :D

i'm glad to see a little bitchin
what we need around here is a good fuss. like on the old list

..well...maybe not when it comes to the ultimate prop. :D
:) We're workin on that!

I was wondering how long it would take for one to start on the new site lets see what happens.

OK so here is mine for the night. On page 6 of my XL plans Leonard calls for all dimensions to be " Center to Center". Here's my problem; I got brave enough to think about welding up station #1. On page 4 the drawing of station #1 is a little iffy as to weather the measurement is center to center or end to end. On page 8A the measurement is definitely shown end to end. Any guidance appreciated. When all is said and done, (welded), I guess the most important dimension is the Engine Mount dimension .

we've been way too sweet. it's boring me to death. we're just an info outlet. we gotta work on our old list personality. somebody snap at somebody

I don't dare snap atcha. I need you guys too much and fear a shunning.::)

I think someone should build a XL Trike!

I am a newbie builder to the DE and am a bit stumped by one item: On Mr. Mulholland's full size rib drawing for the LE (including DE), looking at the Upright stick (which is nailed to the spar) and is drawn with solid lines. Alongside is a dotted line with the note "Double Eagle" pointing to the dashed line.
Is the location for the DE upright replacing the Legal Eagle upright at the dotted line or is the DE upright simply glued to the back of the LE upright? Otherwise all is A-okay.
Sounds dumb, and I apologize for this post but have glued this first rib up to that point and am a bit confused. oment so decided to take a chance and post this to you more experienced builders. Quick reply would sure be appreciated.

Looking at the DE rib drawing it occured to me that the location for the DE up in question is there to reinforce the upright stick for the LE. Went ahead and installed a doubler. If this is wrong, please advise. John Reinking
-
I know on my DE, the root ribs and the rib by the strut attach fitting required a doubler since the vertical piece had to be partially cut out to accommodate the 1/8" thick fittings. Perhaps this is what the drawing is indicating.

Ah, good! Was afraid I'd have to make a new rib. Thanks, Rob.

I also am a newby and first time builder. Building the DE. Doin the ribs at the moment, (lots of fun)
Of the 28 Ribs i note there are aileron and Non Aileron Ribs. I have Leonard's full size rib drawing that shows what i understand to be the aileron rib. Is there somewhere in the plans that shows what the non aileron rib looks like. I cant seen to find a picture of it. Leanard talks of it in the video but i cant seem to see a diagram.
sorry if this has been raised before, just need to know so i dont build too many of the wrong ribs

Paul, A DE builder will probably chime in with your answer, but you can build all the ribs as "aileron" ribs if you wish and everything will fit. The aileron ribs have slightly different gussets near the trailing edge but they will fly just fine in the rest of the wing.

Thanks Sam , that does help somewhat but was still trying to figure out what the difference is.
cheers Paul:)

Paul,
Look at dwg 38. It shows a rib member located for the aileron nose rib. This is an "aileron rib". The remainder of the ribs don't need this piece, it can be omitted.

Hey Sam I think I get what your saying. I have attached a PDF with some notations.
I have highlighted the Capstrip you say is not required in the non Aileron ribs in pink (the one that butts to the Aileron spar Web) This cab strip and the 2 gussets can be omitted.
What I am wondering, and think I have seen in an image somewhere in what i believe to be the NON Aileron rib is a replacement capstrip that runs from the top of the Vertical capstrip in front of the pink (one to be omitted) to the bottom of the one behind the omitted (pink) one to reinforce the structure due to the now omitted (pink capstrip). I have drawn this and highlighted in green. This is what I am trying to ascertain..
Hope this makes sense. Sorry if i sound like a dog with a bone on this but just want to get it right. no point in building ll the ribs and have the inspector send it it to the bin.
I so appreciate your help. Being a newbie sometimes is a bit daunting, but Questions are the way to go. Hope to learn heaps at Oshkosh.
cheers and blue skys for all - Paul

Omit the pink capstrip from the non-aileron ribs.
The green capstrip is not needed in any of the ribs.

Thanks Sam
cheers Paul

I don't have my plans in front of me, but I thought all the ribs are built as aileron ribs on the DE and are all the same. That is how I built mine. How did those of you with flying DE's build them?

Yup, all of mine are the same.
