Posted: Sun Sep 22, 2013 11:17 am Post subject: Spar won't come off the socket!!

Is there enough clearance to slide a knife blade between the spar and socket? If you sight down the pin hole when you do it you might just be able to see what the problem is an maybe even cut through it!

Andrew,

Try heating the spar socket to allow the spar to be released. You may have to redo the setting.

Redux will soften at moderate temps, I'd try that. Heat the socket on the outer surface, 

quickly and quite hot, Heat the pin socket too,then give wing a strong pull.

If you can get a wooden spar to lever between fuselage and wing root rib with wooden

pads to spread the loads that would be the way to break the stuck part.

Andrew,

I concur that heat will soften the bond, but a paint stripping hot air/ heat gun is probably the tool for this job, but would recommend you practice on some uncured scraps of fiberglass first ,apply the heat and you can see that the resin will soften enough to peel the layers of glass apart, also protect your spar around the socket, wet towels or similar.. you can set up a temperature probe on the spar if you want to be sure you do not ruin it...

 

To set some limits to help you prevent damage to wing / spar or surrounding areas ,some guide temps used for post hardening 50 degrees centigrade for areas near blue foam.... 80 degrees for areas where no blue foam ,while piece is fully supported (as parts will deform) is used to heat soak composite over 18 hour period.

 

By testing with a piece of steel on a glass fibre scrap..or flox and resin scrap you will establish how long you need to apply the heat to the socket to allow you to pull the wings apart.

 

Good Luck !

 

Kevin

Thanks to everyone who responded. It seems the problem was I had overestimated my upper body strength  I was trying to pry the wings apart by pushing on each wing root. Instead, I inserted a bottle jack horizontally with a long 2x4, and I was able to pry the two wings apart There was indeed some epoxy around the bushing. It was not much, but I guess it was enough to cause a significant resistance.

 Subject: Re: Spar won't come off the socket!!

  

 

Thanks to everyone who responded. It seems the  problem was I had overestimated my upper body strength  I was trying to pry the wings apart by pushing on each wing root. Instead, I inserted a bottle jack horizontally with a long 2x4, and I was able to pry the two wings apart There was indeed some epoxy around the bushing. It was not much, but I guess it was enough to cause a significant resistance.
