Oh no - how did you manage that??

What you could do is drill a small hole in it if it's still accessible, then screw in a small self-tapper and pull on that - should pull the ferrule out with it... maybe. :blue-confused:

attach a hose to one end, turn on the water gradually and it should come flying out. Could also try blowing while holding rod upright.

If one was able the slip in like that, then the other is most likely somewhat loose or could be easily worked loose enough to pull it out.
Then you could use some type of rod to shove the other one out.
Then you can glue both in place again and go flying.
Good Luck!

When that happened to me
I just consistantly tapped the end of the spar untill the ferrule fell out.
When its out araldite it back in place,
but be sure to clean the shoulder after.
Good luck.

Solid, stick something to the ferrule using super glue, then pull it out.

Hollow, from other end slide in a thinner piece of carbon or glass fibre, push it out.

Or the tapping above works to.

Using something to push through the rod is the best way. Tapping if you hit too hard can splinter the end. Not that, that is detrimental to the rod, but I like my stuff kinda pretty. Thats a joke btw. You've got a few dual liners. I'm sure you have a lower spreader that'll fit. We used to use Zap super glue with the accelerator on the field. If you don't like to wait that is.

Sometimes if you hold the other end and give it a "whip" action, enough of the ferrule will come out so that you can get hold with pliers. Another way is to hold the center of the spar with the bad end downward and tap against the edge of a table or similar object.
If you can get the other ferrule out, then you can use a long rod or compressed air to drive it out.

If all fails, cut the other ferrule off flush with the spar, and use it as a vertical. Not that I have ever had to do that, mind you.

Every so often I remove the leading edge spar and check the ferrules. Several times I have found they need to be re-glued. I think they work themselves loose from the constant flexing.

Check all of your Revs.

i gotta say this never happened to me before .. if i were you i would tryl to blast it out with forced air meaning a compressor or your mouth.. if it is jammed to tight for that then tey a small rod to shove inside the bigger rod and try to wedge it out.. if you do get it out then glue it to the point where it wont happen again..

Ok, here's how to fix it without any drilling or glueing or damaging your spar.

I am going to assume that the ferule that slid into the other spar is the center rod, therefore you can't push the ferule out from the other end because that too has a ferule on it. So, here's how to do it.

Grab your leading edge end rod and some clear scotch tape, put the two rods together and hold them as tight to each other as possible. Carefully tape the two rods together end-to-end with the tape so that they are perfectly round and not offset. Then take the two rods that are taped together and drop-tap the end of the rod that doesn't have the ferule on it onto the ground vertically so that the rods suddenly stop and the ferule will slide out of the top rod and into the bottom one, drop-tap the rod on something very solid like ceramic tile or smooth cement or a hard countertop (if you have enough ceiling height). Tap a couple times, check the two rods to see if they still wiggle, tap a couple more times etc... until the rods are totally stiff from the ferule being tapped/slid into the other rod. Untape the rods and then re-glue the ferule back to where it should be. If you tap to much and the ferule goes all the way into the bottom rod, untape the two rods and then push the ferule back out from the back side.

Hope this makes sense, easier to show than to say.

Perfectly clear.

Thanks, that's one to file away in the old gray matter for future reference.

:w00t: I feel like such a dork for not thinking of the ferule on the other end of the rod. :kid_frustrated:
My Rev 1 has outter sleeves on the center rod. So the outter portions of the LE slide into the middle instead of over a ferule.
Just noticed though that my fathers Rev 1 thats only 2 weeks newer than mine has the internal ferule. Weird.
