I don't remember who was asking about how to repair their 20 year old kayak,
but Nick's board just had an excellent post on the use of polyester resins.
Since I don't "think" epoxy resins were in use 20 years ago, it is most
likely a polyester resin was used.

Hope this helps,

I was using Epoxies back in the early 1970s to build whitewater canoes and
kayaks.  Was lots tougher than polyester, but polyester repairs would work,
even on epoxy.  The epoxy adheres better, though, so I'd recommend it.
Some are better than others.

OH dear. Now I have to admit to being older than Hank.

I built my first epoxy boat in 1961. Designed for the Little America's Cup
it was a 24' Styrofoam cored catamaran for Bill Cox. A lovely boat but the
rig was too heavy and it finished second (I think) in the trials. In those
days epoxies had some rather potent amino acids as curing agents.
Apparently the body confuses the amino acids in the body with those of the
epoxy and workers developed strong allergic reactions. (I am not sure this
explanation is completely valid as no one took time to explain it in detail
to the expendable shop workers).

To make along story short, some workers developed severe allergic
reactions. Others developed more serious complications. In my case, a love
of boats. I also developed a minor skin problem under my school class ring.
The ring fell off one day along with a lot of skin.

Later (1970) I worked for a company building Ferro-cement boats. We used
epoxy for everything. Because some epoxies cure in the presence of water we
could bond new concrete to old by smearing on epoxy before applying the
concrete. Great stuff that epoxy. Wish I could find it again but the fellow
that formulated it has passed on to the great chemical plant in the sky.

Epoxies these days have improved a lot and I suspect they have less
toxicity than polyesters.

Some epoxies will cure in the presence of wet polyester. At C&C Yachts we
built a rather clever  rudder using a stainless steel frame. To get the
polyester shell to bond to the stainless we first coated the steel with
epoxy and then applied the polyester while the epoxy was still wet.
Everything cured together and it stuck as if we had used nothing but epoxy.

Does a previous life in sailboating count?  Not sure I'd admit it if that
was the field I came from <grin>.

Been there, done that, gave up.

First year of sea kayaking I just threw my Werner paddle in the back of the
truck without breaking it down.  When I finally tried to break it down it
was corroded together.  

After trying everything I could think of I started working on it with 2 vice
grips.  I got them to turn but was ripping up the fiberglass handle with the
grips.  

While fooling with it the push button got stuck.  I used a screw driver to
punch it down and it jammed inside the paddle.  I'm not a patient man so
just duct taped the push button hole and have paddled that way since.

I don't know if soaking the paddle for a 'long time' to loosen the salt
would help or not.  Vinegar helps break down some kinds of corrosion.

Had a similar problem with mine a few months ago.  Since I need it 
to break down in order for it to fit in my "system", I got another 
person to help. I had them hold one blade firmly with the button 
depressed, while I twisted the other.  I was able to get it to rotate, 
and then pulled it apart.  The problem, in my case, looked to be 
caused by really fine grains of sand that had worked their way in 
the joint.

I believe it is principally salt crystallization that causes most of the
problems.

1.  Poke the button inside as mentioned already, just to let water inside.
2. Soak it in the pool or other fresh water for a day, then try the 2-person /
blades-under-the-armpit twist method described by Richard.
3. Soak it in vinegar as suggested.  Wrap a rag around the joint and button
and keep it saturated with vinegar (white cider probably cheapest -- flavor
optional) for several hours.  Or fashion a cup around the shaft with duct tape
and a cut-up plastic bottle, then fill the cup with vinegar to cover the
joint.   Do the twist.
4.  Still nothing?  Yikes - now the scary one. Heat the female side of the
joint to try to expand the tube, breaking the bond and winning a (very) slight
clearance.  You can try pouring boiling water on it, use a heat lamp, or (and
this is the dangerous one) use a torch.  This works best on aluminum shafts,
but can work on glass or carbon shafts.  The idea is to heat the outer tube
quickly, before the inner tube can also warm, so heat-soaking doesn't do it.
Hopefully someone will pitch in with info on how hot the composites need to
get before they soften or catch fire.  Be gentle.

Good Luck, and no -- I won't buy your smoking, dripping epoxy-carbon paddle.
:-)

BTW - if you do get it apart, _never_ use any lubricant on the ferrule except
perhaps a very light coat of silicone spray.  Any oil-based product will gum
up like crazy in salt water (can someone tell me why)?.  If you already used
the old 3-in-One oil, you may need to do like Clyde and turn it into a one-
piece.  Oh, of course you could also send it to the manufacturer and have them
restore it for a fee.  

Hank - what say you?  If you are listening, you must have some better
suggestions than these.

I have several Werner Camano paddles (two for a double boat and one for
a single).  When I first got them, I noticed that sometimes paddlers
were struggling to take theirs apart even when used just for the day. 
MIne sometimes took a little doing to take apart.

A few weeks later I was at a symposium in which Werner had a rep.  I
asked about this and the rep from Werner said to do a bit of sanding of
the male end of the connection.  Just a little bit with very fine
sandpaper for a smooth finish.  I did and the paddles never again
threaten to stick.  I have had them 10 years and the connection remain
free of sticking and the connection does not wobble when I paddle.

Remember, this is advice to be taken carefully.  You need to go about it
gingerly.  Too much sanding and the connection will get floppy.

Harold,

>suggestions than these.

I don't.  I have not, and others I know who've tried it, also haven't had
any luck with the soaking method, but it might work sometimes, given a long
enough soak.  It depends on what the "glue" is that is holding the thing
together.  We've actually not had a lot of problem with this, maybe a dozen
people have complained about it so far in over 10 years we've built
paddles.  And (unfortunately?) it happens to every brand, not just ours.
The ones I remember that we have gotten apart were mostly sand in the joint.  

Our prevention advice is to take the paddle apart after every paddling
session.  This condition normally happens after a long trip or after
several shorter ones where the paddle wasn't taken apart between the trips.
 This allows the grit, salt or whatever the glue is to build up.  Take the
paddle apart after every paddling session and rinse the mating surfaces
off.  Store the paddle with it taken apart (and remember to take both
halves when you go next time!).  

You (and others?) mentioned they thought sea salt was the problem.  We've
actually had more problems with whitewater kayak paddles than sea paddles.
Beach sand when surfing is the biggest culprit.  A few others that were
*really* stuck where the boaters had done glacial rivers and the constant
immersion in the silty water glued their paddles together.  Most eventually
got their paddles apart, but one guy in New Mexico (who traveled) just left
it stuck together and later ordered another breakdown for his traveling
trips.  

I contacted Robert privately when this thread started and recommended he
send me the paddle (he replied he would).  His is an Ultralight and they
won't take lots of reefing on when trying to get the sections apart.  I
don't want him destroying a $350 paddle.  If nothing else I can saw the
ferrule out and install a new one.  I'm gonna try a quick soak and the heat
gun to see if either will work first. I'll try and remember to report what
happens.  Bug me if you don't hear.    

I hesitate to recommend Ralph's trick with fine sandpaper on an existing
paddle, but if the fit is already *real* tight, you might be able to get
away with it.

I've had all the methods I described work on various paddles.  And then there
are those which became permanent one-piecers.  I try the methods in the order
stated, escalating the violence until the joint or my will break.

<<Our prevention advice is to take the paddle apart after every paddling

Yes, absolutely the best way.  I disassemble mine after most paddles.  Its the
thirty or so lurking in the trailer box that I often never mess with until
someone tells me they can't feather the paddle they're using.  Occasionally a
customer will bring one in that has been together for many months and many
paddles, or which has been lubed with petroleum products, and the violence
again escalates.

Hank:

Amazing an amazing thing happened this afternoon:

The paddle is now unstuck.  I bought the wood 2X2 to give it some
protection than took it to a private P.O. to get a shipping package built
for it.  At the shipper's the shipper decided to give it one more try to
get it apart.... AND IT the paddle just parted.

I didn't get to try the vinegar soak, but I guess it needed some "tapping"
or vibration to loosen it up.  Anyway, now it's apart.

Thanks for all the help and suggestions.

I just had a thought regarding periodic cleaning of the mating surfaces now
that they are apart. Rather than using fine sandpaper, why not try
auto/marine polishing compound? I imagine that as long as the male and
female surfaces are maintained at a shiny state (no oxidation) chemical
bonding would be retarded. Whether or not you choose to apply a silicone
spray would be a secondary choice

The biggest problem we seem to encounter with stuck paddles (although 
one often really never knows what the "glue" is) is paddlers 
lubricating their paddle joint with WD-40. Our line is that "WD40 and 
salt water make concrete!"

I use 303 and/or a light silicone spray on the joins of my paddles.

As for the bollixing water trick, I did that recently shift a joint, but
assumed it was still a good bond. WRONG. The feather kept changing without
me realizing until one of my friends noticed I had a 120 degree feather.
Some duct tape did the trick for the rest of the trip, and my elbows stopped
hurting!

I tried to get 303 into the joint.  It seems it didn't go.  Best to apply
before you put a tight fitting joint together.

I've been using Vasoline for a couple of years for easy breakdown. I haven't
paddled much the last two years so don't truly know how effective it is, but
so far it seems to work like a charm.

Probably one of the worst choices one could make:  eventually destroys the
resin, and picks up sand big time.  Silicone would be my choice.  303
probably won't hurt the joint.

Re: heating the joint:  an industrial strength heat gun is a much better
choice than an open flame.  To get the right kind of gun, find a buddy who
makes RC airplanes and use the heat gun designed for shrinking the plastic
covering on the models.  Hair dryer won't cut it.

Dunno, Robert.  Didn't have dynamite, blow torch was out of fuel.  Guess I
figured acid disfiguration was the next-most suitable punishment.

Sadly, it only loosened the join rather than scarring the paddle.  Later, a
chemistry teacher tried the same thing independently and found it worked even
as his wife had me on the phone, frantically asking how to get her new paddle
separated.  Probably something I should remember from Chem 101. :-)

 Great stuff that epoxy.

So for the lay person.....Should we consider epoxies interchangable with
standard polyesters for general boat repairs?  By epoxies I'm assuming items
under the West or MAS labels, right?  Will standard gel coat adhere to an
epoxy based repair as well as a polyester based repair?

Thanks
Dennis

No. For example, only certain epoxies will cure properly in the presence of
water or at low temperatures. For in-the-field repairs polyester cannot
replace the proper epoxy. If you must laminate to white oak, polyester just
won't cut it. If you wnat a good colour match on a polyester boat, epoxy
won't cut it unless you paint it. The bond between polyester and epoxy
vaires with the type used. Best to use epoxy for all repairs on epoxy boats
to be safe.

West, East, MAS, System Three, Fiber-Glass- Evercoat, etc formulate
epoxies. Most work fine if you follow the directions. Mosty boat builders
go straight to the manufacturers (Ashland, Reichold, Ciba-Geigy etc.) for
products tailored to suit their needs.

Far better to use polyester throughout to assure no problems. Mixing and
matching can cause problems that the pros know how to avoid.

        The general folk wisdom appears to be to use whatever the boat was
made of in the first place but if you don't know for sure, use epoxy.
        It also appears true that you can always stick epoxy onto older
epoxy or polyesters, but polyesters will not stick to epoxies --  something
to do with the surface characteristics of the cured stuff.
        Could be true.  I had a decked C-1 someone had tried to repair with
poly resin and I was able to remove it with my fingers and a good pull.
Replaced it with FG & epoxy resin, never had a problem again.

Check with FOX Industries, USA, or Sika, for thier Sikaflex product.  These
are similiar two-part epoxy products specifically formulated for the old
concrete to new wet concrete bond and are routinely used in the construction
industry.

Having recently consulted with Current Designs technical staff for a sail
mast step installation on my Pisces, they recommended the use of Polyester
resins rather than epoxy when bonding to their hulls.
