Compound curves

All,

I'm struggling to get a decent finish on wing tips with compound curves when using oracover.

I've looked up videos on line and read lots but just can't seem to master it.. The technique I'm using is to use a heat gun to stretch the cover over the curve. The challenge is that I continually get creases in the finish and if I go too long with heat gun it crisps up as it's too hot.... The iron approach isn't much better..... Any of you experienced flyers have any advice??

Thanks

andrew wallace:
stephen could you take a picture of the curve
normally i use the heat iron and stretch the film, some times i'll run the iron up the middle first and then work out the ways
is there much of a stretch with oracover i've never used it before

Fred:
Same as Andrew.
But sometimes, the curve is too "steep" for the material to stretch properly...
Scissors, and a few cuts every 5mm will sort you out, and with Oracover, will be pretty much invisible :)

stephen.shannon:
Thanks for the response on this lads. The photo's enclosed show the curve. Its very extreme really I'd imagine its just my technique.

Let me know your thoughts.



The wing is from a WOT4

Put a nav light. Problem solved  :P  :P

Not a big compounded curve. Go slow, heat the corner of the wood first in following the curve and that should do it fine :)

Not easy to explain/describe  :(

But le Internet to the rescue! :)
