Is it necessary to use a plumb bob and achieve high accuracy when
working with the wing on the wing stand? It would seem that the pre-
punched kit would make this obsolete since all the holes match up
(theoretically, anyway). I am looking at DWG 15 to see how to build
the wing stand. They could have given more info with not much effort
here on the construction dimensions. The drawing shows the posts
about 133 (units of some unknown measure, likely inches) but this is
not from post to post but almost post to post. This, I figure, must
be the distance of the spar ends from the posts, but still no number
given. Any suggestions greatly appreciated. I am gearing up for and
looking forward to the arrival of my wing kit that is hopefully
shipping this week.

There is a guy on the net (can't remember who right
now) that has some good pictures of one he made that
is on casters, I made one like that and am glad I did.
Made working on the wings so easy. If you are in the
Detroit area you are welcome to borrow it.
As far as leveling everything, just build the stand
then level the ends of the spar when it's time to drop
the plumb bob. A Smarttool comes in real handy here.
Wait to set the distance between the posts until you
have the spar and decide how you want to hang it from
the posts, this will have alot to do with the spacing.

Mike,
It was suggested to me by another local RV-9A builder that I check
for twist before drilling out the skins. Even though everything is
pre-punched you can still have twist. I had to make some small
adjustments to correct for twist before match drilling. So, my
opinion is that yes you should do the plumb bob thing after getting
the wing skeleton in the stand.
Some thoughts on the wing stand:
* Decide whether or not you're going to build both wings at once or
one at a time. This may affect the design of your wing stand. I'm
doing a hybrid of this. I setup both wings and did all the drilling
and prep work but will probably only assemble one at a time with one
wing in the stand.
* Wait until you wing kit arrives to actually build the stand. You
can get the materials ahead of time but wait to build it. Having the
spars in hand helps.
* Use something sturdy for the cross braces and support them well to
keep them from moving.
* Personally I think the vertical post stand that Van's recommends is
the best way to go if you can do it. My garage door prevented me
from using this method so I built a free-standing one. It's not
quite as rigid as I'd like it to be but maybe I'm anal.
Todd Houg is one of the builders that built a 'rolling' wing stand.
Website is http://pws.prserv.net/thoug/. I swapped a couple of
emails with him about it, so if you have questions, I'm sure he'll
help you out.
That's my nickels worth of ideas.

The wing stand needed for the 9's is a very simple one. All that is
important is that the two verticle pieces are the correct distance
apart, and that the two horizontal pieces that the ends of the wings
rest on are perfectly parrellel with each other so the spar doesn't
twist when resting on them. A good level will get you there.
Plumb bobs are not needed as part of the structure. You'll use plumb
bobs later to hang down from the ends of each wing to make sure the
wing doesn't have any twist.
I built both my wings at once on a double wing stand made of 4X4
cedar posts with two cross pieces made of angle iron. No braces were
needed because each piece of angle iron went between two posts that
were spaces about 4' apart. That gave me plenty of room between the
wings for working on them and my wings have zero twist. Just make
sure he angle iron pieces are perfectly parrallel.

Mike,
I built one on casters, not very elaborate but it is nice to be able to move it out of the way when space gets tight and the in the middle of the shop when working on the wing. I plan on modifying it into a rack to store the wings after they are complete (leading edge down). as for the twist, I used a fairly long piece of angle stock from the home store. I put one bolt into the upright and the used a couple of cables with turnbuckles at about 45 degrees to stabilize it. even though I thought the horizontals where parallel I found that when I checked with the plumb bob I was 1/4" off. this was adjusted to "perfect" by adjusting the turnbuckles.

Mike,
As Matthew pointed out below, I have some pictures and info on a rolling wing jig on casters at www.toddhoug.com.
It has worked out great and is now used as the primary storage for both wings. Supported from the spar ends just as during assembly. Depending on your available work space, the portable wing jigs can come in very handy.
Drop me a note if you need any more info beyond what's on my website.

Brian, any chance you could send me a photo of your stand. I am ordering my
wings this week and sure could benefit from it. Thanks, Glenn in Arizona
