I'm sure this subject has come up before, but humor me and give me the benefit of your collective wisdom.



I'm getting ready to fit the fiberglass tips to my horizontal stabilizer.  Looking at the tips I see a few problems....

1.) They don't fit very snugly within the end of the stab.  When you rivet them will the rivets pull the tip's edges up to the contour of the skins or am I likely to get some wrinkles in the aluminum skin?

2.)  The open edges of the tips are not straight (flat).  The edge line is curved inwards towards the outside center of the tip.    Should I sand or dress the edges until straight?

3.)  There are some chips in the fiberglass coating around the edges.  Any recommendation as to what I should use to fill and smooth these areas?



Thanks!



Tim

Tim-

     I think we all experienced that problem. On mine I got  as close as possible, filled with Poly-Fibre Superfil and then sanded to a  "pleasing contour." Not flying yet but it sure looks good.

Tim:



This is probably not the answer you want to hear, but

if you want them to fit perfect, just make a new set

like I did here:



http://www.cooknwithgas.com/StabTips.html



For a perfect fit you would have to do like I did and

make a pattern from the exact shape of your

stabilizer. Since mine was scratch-built, it is

probably a little different from any other stabilizer.

 



Search the archives and you will find some tricks to

make those things fit.   Several guys have done so

successfully.

Carroll - where can I get the Poly-Fibre Superfil (and does anyone else recommend a different product)?  I need it for my wing tip fiberglass pieces that suffered the same fate.

 

 BTW, Tim, although I skipped the stab tip when I got to it, I just did my fiberglass wing tips.  The same effect is present - poor fiberglass contour and condition.  I sanded the fiberglass a bit to take out a couple large chunks and then just pushed it in as firmly as possible.  I still probably had 2-3mm spacing at one point in the tip.  In fact, I think the fiberglass and skin both yielded a slight bit.  The final effect is that everything is nice and tight where the rivet goes, but there is still a bit of a gap on the edge that I will have to fill.

Tim,

You can heat them up and gently reform them to get the fit you want.

I recently bought a rolling flanging tool from my good friend, Bill Naumuk, that worked great to make a good fit between fiberglass parts and metal edges that don’t quite fit.

Yes, this is what I did...  Using a heat gun, I heated mine until I just 

started "smelling" the fiberglass smell from it... At that point it formed 

very easily...  My tips fit very nicely...after some persuasion...

Tim,

I used a heat gun to soften the fibreglass and coax

the tips into shape.  Try to make the tips fit the

stab, not the other way around.

The latest issue of  Zenair news (#154 - pg  references stabilizer plates. Bob Jones, of Big Lake,  Alaska swears by them. I'm wondering what the list thinks of his  innovation...

All-

     Check in the archives under  "Fiberglas Wing Tips" which should contain an account of where we listers  collectively came up with a way of dealing with fiberglas parts. I had an  absolute bitch of a time with my tip ribs, but learned enough to make installing  my stab ribs a non-event. As I remember it,

     1. I cut a plywood form the size  of the outboard rib, plus 1/32", and crammed it in the fiberglass tip about  1/2"in.

     2. I heated the fiberlass edge  using my HF heat gun and straightened out the kinks using my "Flattening  pliers".

     3. After installing the tips  (Just press fit, not riveted) I duct taped them down and LIGHTLY applied  heat again, pushing any bubbles down.

         A. Don't go  crazy with your heat. When you start smelling fiberglass, it's hot enough. Keep  the gun moving.

         B. Get  whatever your're holding the fiberglass in place where you want it, keep the  heat on until you get the fiberglass smell, and hold it down for a count of 30.  Repeat as necessary.

     Good to hear you're happy with  the flanger, Gary. I haven't touched my project in 3 weeks and it's driving me  nuts just talking about it!  Doesn't help when I read in the paper  today that my neighbor two doors down just had a truck back up to his garage and  clean out all his tools- especially when there aren't even any nails in my  garanger windows!

     Chris couldn't have been home  at the time of the robbery, or there'd be a God-awful dead smell on the  side of the road up a piece!   

     No, I don't consider  myself a redneck- in fact, I have 3 college degrees. Just don't mess with  my shop! 

                                                                                                                                                          Bill 

                                                                                      do not archive

Being a redneck has nothing to do with  education...  Being a redneck is the glorious absence of  sophistication.

Actually, the redneck comedy of Ron White is more appropriate for experimental aircraft builders. Consider the routine about a commuter airliner flying along at the speed of smell, and the observation that the second engine is good to get you all the way to the scene of the crash. If fact you make such good time on that one engine that you'll beat the paramedics to the crash site by almost an hour.

John-    

     Degrees or conibears?  

     Having 3 degrees just proves  that by the time you graduate with one, the bar has been raised and you  have to get another. Having 3 conibears on your workbench means you still  have all your tools, and there are a batch of moochers walking around in  casts.

     Sheesh! When I hit the wall (Or  more accurately, the size of the basement door) I couldn't wait to get started  on the garanger. Now that I've hit the wall on the garanger (Waiting and waiting  and waiting for a garage door) I can't wait to get back to work on the plane.  

     With the entire list as my  witness, I swear I will never contract out anything I know I can do myself. If I  would have just had the pad poured and let it go at that, I'd be done by  now.

                                                                     Bill
