Posted: Mon Feb 20, 2006 9:58 pm Post subject: Covering wingtips- fabric reinforcement plates

I am nearing the point of covering my wings and I have a few questions.  My 

manual says to trim the fabric a few inches out onto the wingtip for 

non-removable tips.  My Avid Flyer has the entire wingtip covered in fabric, 

but this suggests the fabric will end just beyond where the tip screws on.  

I want the covered tips to use the polytone to the end.

   Also my manual shows the strut bracket reinforcement plates for the 

fabric.  I assume these go under the fabric, but find no mention of 

installing them.  Do they rivet to the spar over the strut attachments?    

Boy do I feel brain drained....      Ron NB Ore

Are you fixing your wingtips to the wings with rivets, or screws so 

that they can be removed at some time? I let my fabric stop at the last 

rib and screwed (with anchor nuts riveted to an added-on aluminum 

strip) the wingtips on. If you're going to cover the tips, never to be 

removed, then of course let the fabric go all the way to several inches 

past the wingtip.



The reinforcement plates are merely glued to the under side...inside of 

wing...of the lower fabric with poly-tak. One of my manuals (one is 

original 1993  Model IV manual, the other is the Classic IV manual of 

2003 revision) says to pre-coat the plates with poly-brush (two coats) 

and the other manual doesn't mention the pre-coating (or at least I 

couldn't find it quickly), then attach with poly-tak. You have to coat 

one side of the plate with wet poly-tak and quickly slide it in place 

over the strut bracket, and position quickly and then hold in place, 

pressing the fabric onto the plate...it's a messy job. MAKE SURE that 

you get these plates in/on before you start the top fabric...nearly 

impossible afterwards...no, forget nearly, it IS impossible.

Ron,



I built my IV-1200 so that the wingtips could be removed.  This made 

it very easy to cover because the fabric just goes over the end of 

the last rib and the tip screws on over that.  Yes, the fiberglass 

had to be painted separately, but at condition inspection time it 

sure is nice to be able to remove a few screws and see the entire 

inside of the wing.



Just a thought.

I have one wing with the added-on aluminum strip installed (previous

owner), but the wing is not covered.  Can I cover this added-on strip

with fabric?  Will the fabric have enough hold if it doesn't wrap around

the end rib cap strip?



Thank you,



Matt

Matt,

I wrapped the fabric around the wing tip supports.  Take care if you drill and mount the wing tip attachment hardware before covering with fabric,  the mounting holes will not line up due to the slight increase in thickness.  I have not yet drilled/mounted the wing tips,  (will do so after paint)  hopefully I am not in for an unpleasant surprise!

I found the best way to put them on is to tape them to the lift strut 

attach bracket then cover the bottom of the wing. Shrink the fabric to 

about 275 or just tight. Brush polybrush around were you need to cut for 

jury strut and lift attach bracket. When dry cut with a  razor blade and 

the protrusion will pop through in just the right place. Turn the wing 

over and glue down the aluminum reinforcement plates to the fabric.

Lynn I was planning on covering the wingtips.  It does have the riv-nuts 

installed now so maybe I will go back to the idea of removable tips.   The 

prior owner had covered them and my mindset was stuck on that road.  If I 

must trim and redrill anyway I wont be concerned about his poor fit and 

attachment.  Alan and everyone great info on the reinforcements, I made them 

on my lunch hour and will tape in place before they get forgotten.   Thanks 

to everyone for the push as now I will be removable and possibly extendable.

What tipped you off to the "race fan" thing, Ray? Was it the orange 

(Tony Stewart colors)....the bare amount of white (typical of 

unsponsored race cars)....the black (perhaps Kevin Harvicks' 

colors)...wait a minute, NO, don't tell me it was the graphic on the 

vertical fin? That thing that *looks* like maybe a number three? Now 

who could THAT be? Yup, Ray, it's true, I'm a race fan...gotta admit 

it. But you'll notice that I made the "3" just enough different from a 

particular copyrighted #3 that I hope I won't get any visits from 

Richard Childress's lawyers telling me to change it. Maybe as a 

precaution I'll keep the plane in the hangar when the Nascar boys come 

to visit this summer at nearby (15 miles) Michigan International 

Speedway. Or maybe if I'm flying it by then, make a pass close enough 

to MIS to let 'em know how REAL Dale Earnhardt fans express their 

undying loyalty.



Just for grins, take a real close look in the background of the plane 

picture, and you might see two vehicles lurking in the dark, both 

wearing a #3 front license plate...hell, it's the real reason I moved 

back to Michigan from California....no front license plate requirements 

here.

Yes, that's what I did...rivet the aluminum strip to the underside of 

the last rib cap, then when it's time to cover, press the fabric down 

into the right-angle formed between the cap and the aluminum strip, 

across the strip, around the edge of the strip, and cement under the 

strip. It'll hold 'til the cows come home....actually longer than THAT, 

thank God!  I'm not sure if the fabric would hold just being glued to 

the strip itself, so why take chances. And don't forget that this area 

will be covered with the pinked finishing tapes, which I also formed 

down into the cap/strip interface.

Thank you for the reply.  I can't tell you how happy I am that I don't

have to take another part off this wing.  Now I'm moving forward.
