This is a question for Chad and all those that have built wing stands based on Rudy's design.
Why couldn't I just level off the arms that come off the posts that I have anchored to my floor and put two stabilizing screws through them to keep them level on the posts? In other words, do I really need to fab up the "adjustable arm" pieces or is that sort of a redundant component?
The reason I'm asking is as a rookie builder, I won't know what I could be setting myself up for by not having them adjustable.
Let me know what you think?!?
THANKS!!! - Peter
PS - Oh yeah...my wings came today! WOOHOO! I'll spare you the ABF pictures, but I did take them!

Peter, you don't need the adjustable arm thing on both sides. I didn't.
I did put it on one side though. I thought that I might need to remove a twist if one appeared and it really didn't so I am not sure that an adjustable anything is really necessary.
Build a simple jig and if it isn't working like you please, modify it.
One bite at a time!

The adjustable arm is redundant, but it does make for an infinitly adjustable arm in the smallest degree needed. You don't need it though. I think you could build the wings without a jig if you're careful. They are just so well engineered, that it ALMOST makes the jig unneccesary.
Fabbing the adjustable portion only took a few minutes once you have the materials in hand. You probably don't need it but fro mmy experience it could be the quickest way to get them level.
Actually drilling the holes in the concrete was the worst part. I eve nhad a good hammer drill and it was still a pain.

I just finished this arduous task recently and did the two adjustable arms per set of stands. I found that having two arms made it easy for me to zero each side. Like John said, do whatever works. I am amazed (well not really) at how easy it was to fit the skins after everything is set up. I assume that if you built the wing flat on a bench the skins would set your alignment pretty well, but I didn't want to test my theory.
Thanks again Guys - I fabbed everything up and pounded them out today and they're done. I'll be sarting inventory tonight and hope to get is mostly done before the weeks travel begins again on Monday.
By the way, I went RED on mine because I hadn't seen a set that color yet...

The angle is attached to the rib via two holes I drilled in the rib web just for this purpose.
The root end is just clamped in place with a piece of paper between the spar and arm to prevent scratching and piece of wood on top for the same reason.
Thanks to JohnR for lending me his awesome wings stands! I mounted them to the concrete today:
It was really easy - I used 1/4 inch tapcons. The hammer drill went through the concrete like butter with the special tapcon bit. Came out nice and sturdy and the spars even fit.
I'm building in the small one-car side of a 3 car garage, so it's getting tight. I have 29 inches between the spars which will have to be enough.
THANKS JOHN!!! You're the BEST I'm hoping to be catching up to you on a fuselage by fall.

Dave, glad to see you got the stands put up! It is good to see those stands working again! Maybe by the time your done with them Kevin will be ready for them. You out there Kevin?
Oh yeah, thanks for the chocalate chip cookies, they were great!

I had no idea there were so many RV builders in New England.... I lived in Nashua NH for 17 years and only saw a few.... Myabe I would have stayed back East... NOT!
(I do miss the seafood, though)
