How to remove stiffeners

5 posts in this topic

Posted

Fellows, I am trying to get the spar stiffeners out of the wings and I can't find anything that will loosen the glue.  What is the trick to this?  Also, the one stiffener I can see looks like regular plywood.  It looks to be a 3 ply.  Also, they didn't center the stiffeners on the strut fitting.  Should it be?  Thanks for the help.

a heat gun will soften the glue and you should be able to knock it out.

Thanks again AK.  Heated the tubing up pretty good and started working it with a piece of wood.  It took a couple of tries and it finally broke loose.  Had to clean the tube good afterwards, but it worked.  Thanks again.

Now I am getting ready to extend the wing and make a long wing aerobat wing.  I am only extending it 3'.  Will I have problems with that or is that the correct length?

Hi Japowell.

How is the wing mod going? I am also about to extend my aerobat wing. I got some documents from the British LAA / PFA. Do you have any drawings or instructions for this?
