Posted: Wed Apr 26, 2017 5:47 am Post subject: aileron gap seal: when?

For you Twinstar builders/restorers, how/when do you install gap seals? 



My 1st gen plans say to install the seals before installing the hinges. I'm planning on using the latex finishing method, and I've used the Stewart water based glue for covering. Do you pre-shrink the gap seal fabric and glue it on after the rest of the finish work (final paint), then repaint after attaching the gap seal?

Thanks,

Charlie

Charlie E/Kolbers:

 

Haven't covered a wing in 17 years, so if I am wrong someone will promptly correct me please.  

 

After you shoot the last coat of Polybrush (sealer), the gap seal is cemented to wing and aileron.  I think I used 3" finishing tape and it is not shrunk.

 

Use a small needle soldering iron to burn out the rivet holes.

 

Hinges are riveted after finish painting.

Hi John,

       

       Thanks for the info. Your description is how I'm reading the       plans. But I'm not sure how to manage a 12' aileron (flaperon) and       a 15' wing when I'll need to flip the assembly numerous times       while applying multiple finish coats, and keep the two components       aligned well enough to avoid peeling off the gap seal from at       least one side.

Very gently....

 

Shoot one side and roll the wing and aileron over, being careful of course.

 

Poly-tak cement is very tenacious.  I never had a problem with separation during processing and finishing.

Hi Charlie/John,



The instructions for my MkIII Xtra was to complete the wing and attach the ailerons.   Then use  two strips of 3M  Book tape, 3 inch wide,  that are overlapped upon each other with about one inch of sticky side tape exposed.  This will give you a one inch sticky edge facing down on one side and up on the opposite side. 



Then you stick this "Modified tape" to the bottom of the wing and top of the aileron , bridging the gap between the wing and Aileron.  I also did the exact same on the horizontal stab and elevators.   

It still works great and looks fine. 



(I think it was bottom of wing and top of aileron  but it could be the other way round) 



This is another option..  and can be done when all else is finished..  I just cleaned the surface well and used tack cloth to make sure no dust , etc ,  was trapped in the tape. 



My 2 cents.. 

FrankD



MkIII Xtra, hollister Ca. 



PS..  I have decided to sell  my Kolb , in case anyone is interested..  want to give this list the first notification before I post in Barnstormers. 



Cheers.

Tape is ok, I guess.



Finishing tape is much more permanent.  I've got serviceable gap seals after

25 years and more than 3400 hours service.

Absolutely true, a "Tape seal" is something that will have to be replaced every few years. But it is quick and easy and cheap to do.

I don't know that a couple strips of finishing tape is all that expensive.



Takes a little more time, but trim tape looks a lot more professional and 25 times more serviceable if I based that opinion on changing out sticky tape once a year.  



There is more involved in replacing old tape that simply pulling off the old and sticking on the new.  There's the matter of cleaning up the old tape residue that seems to remain more on the fabric than on the tape.  I have yet to see any sticky tape stay stuck when used as a gap seal, especially in the area of that pusher prop.



I took a great deal of time and pride in my airplanes.  It paid off.

Well, I took a shot at living in both worlds. The blue stripe is 

painter's tape. Trying to keep primer & finish off the bond line on 

trailing edge & aileron leading edge. Hoping to complete the finish, 

then get a good bond on the finish tape as gap seal, then do the 

finishing on the finishing tape.  A bit more trouble than binding 

tape, but less hassle than trying to flip the wing repeatedly without 

assistance.



I'll let the list know how it works out.



As a reminder, I'm using Ekobond for fabric attachment, and latex for 

primer/finish.
