Chris,
I've painted flat and vertical. I like flat and letting it dry but it take
s too long.
My painter and I simply clamped the spar firmly to a low six inch wide sawh
orse so it would stay vertical, and I fitted a 2-foot piece of 3/4 ply into
the aileron slot and made a couple of legs extending down to get the heigh
t and angle right. We found it easier to paint around than the tip tube an
d was a throw away when finished. The wide top saw horse was easy to safel
y clamp the spar securely.
I originally ripped and angle cut a form fitted 2x4 that was perfectly fit
and we could screw in through the aileron hinge screw holes. However, it w
as lost somewhere in the shop, so when the first ply support above was agai
n lost, we just ripped some ply to fit from floor to slot and put a couple
vertical end triangles to keep it vertical and stable. The painters prefer
red that for fast setup going from prime to seal then topcoating. 4 clamps
and a 4 foot square piece of ply was faster than waiting for me to install
a tube support on wings that didn't have any pre built supports.

Subject: Europa-List: Re: Painting wings
Thanks Alan and Pete for good ideas.
Since I built my wing with no tiedown mod too late for that. But the hole i
s intriguing. Pete, do you know if this is just a hole and relies on the st
rength of the tip alone or is there any structure inside to support the win
g weight?
I guess since you mentioned a tube, this tube probably extends to the outer
most rib which would help distribute the load.
I wonder if just a hole would be enough. The wing is not really that heavy
at the tip. I do have an aluminum plate for the wingtip light so that would
at least distribute the bearing load a bit around the hole. But not sure t
he wingtip alone is enough to hold the load. Can't remember if the spar ext
ended into the tip. I would assume it stops at the outer rib.
