|
|
Kolb guys,
I have a question regarding the pop rivets on the fabric on the wings.
Is there a proper way to drill the holes? What I mean is, should I drill all the holes in the ribs FIRST, and then melt the holes through the finished faric, with a soldering iron? Or, would it be better to do all the fabric, reinforcing tapes, etc, and then drill through a final layers?
It would seem to me the better way would be to drill all the holes in the ribs first. The reason I think this is because I can make a nice 90* drilling jig, to insure the holes are centered on the top of the rib. I'm afraid if I try to drill the holes after the fabric and tape is on, I run the risk of off-centered holes...making a lop-sided rivet.
Anybody? Anybody?
Thanks,
Mike Welch
MkIII finally (!!!) putting fabric on flaps. So far, Poly Fiber on ALL tailfeathers, fuselage, both ailerons, & one flap. One more flap, and then the wings!! It's about time!!
I just received an email from my step-father, a WW II retired Lt Commander.
He forwarded to me an email of some of the most awesome military photographs I've ever seen.
(mostly flying photos)
If you want to see them, I absolutely guarantee you'll be amazed, send me an email, and I'll forward them on to you. They WILL be worth your time, unless you're a tree hugging hippie!

You need to be able to get ALL the drillings out of the rib tubes by blowing, beating on the the structure lightly to vibrate it or turning it over and over while doing the above.One little sharp chip will find it's way to a pressure point in the fabric and cut a hole in it.You can find the holes with a straight pin or do it like John does.The drill can stick in the fabric and wad it up in a knot.Just my 2 cents worth.

I assume everybody knows about greasing the drill bit to capture chips --

Russ:
Yes, that works good in other situations.
When working with fabric, the last thing you want around it is grease. Might have a hard time getting the grease cleaned up prior to fabric application.

Mike, drill your holes 1st!!Use a string going across the tops & mark them ,
from root to tip, so they are all in a "Pretty-Pretty" line. Then drill them
all with your 90 degree jig you mentioned. After drilling, blow out all the
rib tubing with a compressor. Then stuff a tiny piece of fabric in each tube
that you drilled, so that when you pull a rivet, if that little ball of the
rivet falls off in the tube, it won`t find its way into the interior of the
wing. If any shavings or rivet tips get into the wing, they will find
somewhere comfortable to rest, & each time you fly, tiny vibrations will
cause them to wear through the fabric from the inside out.

I am attaching two pictures of how Brian, at Kolb factory, handles the loose pieces that may remain in the tubes. He probably blows the tubes out first then he seals all the ends as show in the pictures. Silicone rubber would probably be good to use here.

Mike –
At the recommendation of a few fellow Kolbers, I rib stitched my wing fabric, and am very pleased with the outcome. The bump from a stitch of twine is much smaller beneath the finishing tape than the bump from a rivet. Plus, I like to think replacing the fabric will be easier, if I ever have to do it.
Have you considered rib stitching?

If it was me, I'd go with the Polyfiber Installation Manual for covering, attachment, and finishing.
I believe rib stitching was to be used with wooden ribs with flat rib caps, not round aluminum tubing.
I have seen several Kolbs that were rib stitched that did have stitching break or pull loose on top, rear, inboard section of wings. When this happens, fabric ballons up creating some serious vibration problems.
Unfortunately, I have had to recover several of my wings, and helped remove fabric from other Kolb wings. Removing the soft aluminum fabric rivets was not a problem.
