Hi,

I flew my 2-4 today for the first time in one and a half years. I was very rusty (lots of over steer, hehe). I crashed it, breaking the right LE spar. It's a fairly clean break (perpendicular). Can I just use a ferrule to hold the two pieces together?. I have an extra spar but I don't want to use it until I shake the rust off.

Where can I find a ferrule for the LE of the 2-4? (seems the online sellers seem to be short on 2-4 parts)

Thanks.

It could be possible that it has cracks running the length thus would break easily again and it could even do additional damage to the sail.
Best course is to replace the rod.

And try to use a light wind Day to polish the rust off, good luck.

Thanks guys,

The extra replacement rod that came with the kite does not have the ferrule. Can I swap the ferrule from the broken rod as long as i inspect it for damage? Again, I havn't been able to find ferrules for the Blast 2-4 online. (I've also searched to rev website a few times with no luck).

We have replacement spars in stock nearly all the time. I have never had just a ferule though, normally once a rod breaks it does enough damage that the spar is useless. Also, if the rod breaks and you replace the ferule, the rod would be too short to use.

I can probably order in some ferules for you. The replacement rod is less than 25.00, not sure if the savings over purchasing a ferule vs. the rod would be worth damaging the sail.

Just my opinion is all.

I have a new replacement rod (came with the kite), but it doesn't have the ferrule. I was thinking of maybe taking the ferrule from the broken spar (it doesn't appear to be damaged) and using it for the new spar. Or would it be best to get a new ferrule to put in the replacement spar, I'm guessing they are pretty cheap.

After taking the other two LE spars out of the kite I found a second break. The ferrule joining the left LE spar to the center spar cracked in half at the joining point. However, I cannot find any evidence of damage to the left or center spars (not even wear around the edges).

I haven't been able to get the old ferrule out of the broken right LE spar or the broken half of the ferrule of the left LE spar. (The "glued side"). With a different kite I used hot water to weaken the glue. But hot water hasn't work for these ferrules. Any suggestions?

Thanks

Basically you need to get the ferrule to break loose from it's glue.
What I would try, "never doing it before", is to cut the rod cleanly a few inches from ferrule. Then you would need two blocks of wood, a hammer and a solid hard surface.
Place one block of wood flat on the solid surface.
Place the rod, cut end down perpendicular on the board.
Take the other board and place it perpendicular to the ferrule end.
Take the hammer and tap the board on top at the ferrule point.
This should knock it loose.
By no means tap the ferrule directly with the hammer.

Good Luck!
