KR> west system epoxy

[Robin Macdonald]

West Pumps,

To clean, the 105 resin pump wash in Acetone. The 205 hardner pump wash in 
water.

If Resin has crystalised sit container in warm water. If not sucessful bin 
it.

As Gavin suggested always do a test piece

I would suggest the simplest way is to mix up a test batch, glue a couple of
test blocks together then test them to failure after the glue has gone off.

If the pumps are old and full of residue I would order a couple of new ones
from your West system supplier otherwise make sure you remove any residue
from the pumps before using them.

I also always make sure the pump is fully primed by giving it a pump
to clear out whatever has been sitting in the tubes before using it as well
if it has been sittign for a while.

I haven't been able to find any reference in the West Systems doco on the
life of an open container of resin or hardener but If you have any doubts
about the state of the product then bin it and buy some more. Glue is
relatively cheap when compared to your life.

Yes, it protects the wood from water. That is what I said.

[Scott Cable]

Kieth,
I have experience with both, my preference is the West System for a number of 
reasons:
1.) Buy the pump kit-makes dispensing the product very easy and accurate.
2.) I've wetted out Fiberglass, Carbon fiber and Kevlar with both systems, I 
perfer the West System because I just got better results with the West System.
3.) The fumes are  not nearly as bad as Aeropoxy and others-still remember to 
wear your resperator and latex or nitrile gloves.  No matter what resin system 
you use, it's just a matter of time before you start having allergic reactions 
from being around the stuff. Most folks seem to tolerate the West system longer.
4.) I know that I'm probably opening a can of worms here, but the West system 
is used extensively in marine appications because parts made with it don't 
absorb moisture as much as other systems.
  If you check with other groups (such as the Canard or Longeze group) they 
will tell you to stay away from the West System and to use Aeropoxy.  Remember 
the application,  primary structural glass over foam.  Kr's fiberglass parts 
are generally non-structural.

This gives the impression that Aeropoxy is smelly.  I have to stick my nose
pretty close to it to smell it at all (without a respirator), so West must
be totally oderless!  Aeropoxy is maybe 1/50th as "odiferous" as something
like Vinylester.  I've never tried West, but once I found Aeropoxy I quit
looking for anything better.  I measure it by weight on a scale that reads
by the gram.  I don't think a pump can match that kind of accuracy,
especially after it gets a few years on it.

Roger that!  I worked with Aeropoxy in my garage (connected to my house) for 
several years, doing large layups, and never a whimper from my wife or 
daughters.  But just let me spray paint a metal fitting or open a can of 
solvent and I'd hear about it within 5 minutes.  Aeropoxy really is mild.

>I don't think a pump can match that kind of accuracy,

The pumps used with West Systems are like the ketchup and mustard dispensers 
at the burger place... you have one pump per container, pump down on each 
and get a shot of each.  The stroke on each pump (resin and hardner) are 
different, as are the plunger sizes, so you just pump equal pumps of each 
and get a perfect ratio every time.  It's not the metering type of pump that 
draws from two containers into one outlet.

I use the West System pumps for my Aeropoxy (with the proper size pumps to 
get the exact Aeropoxy ratio).  I love it.  You pump as much or as little as 
you need, no weighing, no eyeballing.  If you're at the end of a layup and 
haven't mixed enough, you just walk over and pump some more and mix it up... 
again, no mess and no weighing.  As someone else mentioned, you just need to 
make sure to keep the containers full so you don't suck air into the pumps 
and not get a full stroke of the pump.  Picture of my pumps at 
http://flysquirrel.net/pumps01.jpg

This is another thread that has come up repeatedly on this list ("will a 
plane built with West System fall apart?") and it's the old "less filling...

KR> west system

[Ameet Savant]

I remember some time ago when I was evaluating epoxy
resins, I found the West system was not "as strong" as
some other products available. West can be used in
structural applications but you will have to modify
your design accordingly.

So far as the KR design goes it is essentially a wood
airplane and using West for non load bearing parts
could be done without much redesign.

Besides the pumps and low odor etc. what I really like
about the west system is that it is available at
pretty much every boat sales/repair shop around the
country, saving a lot of money on shipping and
hazardous material handling fees.

Also, some of the other epoxy resins on the market
used West as a basis to derive their own product.
(This might be heresay.. but I thought I will include
what I heard)

Anyway... just my opinion.

Thanks

More taste!  My KR has all of the wood glued together with West Epoxy.  500+ 
hours over 8 years flying with no glue related issues.  The laminates on my KR 
are a real mixed bag.  Some parts are vinylester and some are Safe-T-Poxy.

I have used west system on my boat repairs and read their (very heavy
book) cover to cover. The west system is as good if not superior to many
other epoxy systems because of the ease of use, 2 types of drying
set-ups and colours etc.. Just be sure to use the proper fillers! EG
filler 407 is best for filleting and not bad for fairing. Filler 410 is
best for fairing and not bonding, 406 is the best compound to mix with
the epoxy for bonding.get it."read the label set a better table" -0-

[David Mikesell]

I have used West Epoxy on several wood airframes and wings. I can't say it
is superior to any others that I have used. What I can say is that people do
not develope toxicity to it as fast as with some others. It is definitely
strong enough and people who claim it is weaker did not do proper tests or
proper prep work before making the joint. I have used t-88 also and found
west to be better for wetting and penetraition to the joint than T-88. Yes
you have more work to do with West for filling, filleting, laminates,
fiberglassing, carbon fiber...etc but atleast it is a epoxy capable of doing
so many things all equally well. West is a very strong and durable epoxy
system, now this is when someone chimes and and says it is made for boats
not airplanesyeah well let me see your airplane take the pounding a
boat takes in ruff water at 40 knotsI have been in very fast wooden
jet boats make purely of wood and West Epoxy and they took one hell of a
pounding without a failed laminate or joint, that is the thing that first
got me interested in the West Epoxy system. From then on just using it
convinced me.

I have West System (and also under the Gougeon Bros. name) test pieces of
spruce-to-spruce and spruce-to-various plywoods that I have made over the
past 28 years.  When the FAA guy did the precover inspection (yes that
was quite a few years ago) on my KR2 he could not get a test piece joint
to break closer than 1/16 inch from the glue joint.  He tested them in
shear and peel.  The West epoxy penetrates and actually seems to
strengthen the wood close to the joint.  I would like to know how you
could get a better glue joint than that.  Well, I guess resorcinol
handles heat better.

[Ron Eason]

It's my experience that they are all the same.  They are the same basic 
chemicals. Some of the solvents differ slightly but they are basically the 
same solvents.  Temperature has everything to do with how fast the solvents 
evaporate as far as fume density is concerned. *0% of the time I use vinyl 
gloves because of the mess.

I've been working with epoxy , vinyl, polyester and urethanes for 35 years 
building planes and repairing cars.  I work in a basement that has some 
ventilation and I don't ware respirators while fiberglassing and filling. I 
have never had any skin reactions.
I always practice hygienic procedures as explained in Gorden Brothers 
guides[ wash your hands and exposed areas. [I use lacquer thinner and soap] 
I have used safetypoxy and aeropoxy and west resins and hardeners. I believe 
saftypoxy is the strongest of the three according to lab tests.  I don't 
panic because some chemicals are called hazardous by the EPA just use common 
sense and read the manufactures procedures for the applications.  [ some 
manufactures directions are in the CYA vain however] Just use common sense. 
Be aware and careful of the individual chemicals, after they react [cure] 
they are neutral. If the fumes are to much turn on a fan.
Urethanes are a different matter when painting but not as a adhesive.

I've never trusted twin pump epoxy dispensing systems.  There are just too
many ways for it to not work properly.  Proportioning by weight is the only
way to go for me.  That way I know exactly what I'm getting, and never have
problems.  Pelouze makes a scale that's accurate down in the 1 gram range,
for something like 80 bucks at Staples and similar places.  I have an older
one with a two gram resolution, and it's worked just fine for 10 years...

KR> West system; T-88 proportioning by weight

[Ed Janssen]

I was wondering if anyone has worked out the proper  proportioning for
mixing T-88 by weight?  I forget which is heavier - the hardener, I think.

KR> West system; T-88 proportioning by weight

[Brian Kraut]

1:1 by volume or 100 parts resin to 83 parts hardner by weight.

There is a data sheet on the System Three web site.  It is only 24K so I can
email it to anyone that can't find it.

One other tidbit about T-88 is if you have a local Woodcraft store they
carry it in stock.  My store only has the small bottles, but when you run
out on a Saturday you take what you can get.

KR> West system

[Colin & Bev Rainey]

My experience with the West System has been the same as Orma's. I found that I 
was not getting a complete squirt when the pumps had been left for awhile. So I 
began a habit of having 2 epoxy cups handy, one to squirt just enough epoxy and 
hardener to prime the pumps fully, then dispense the amount I wanted for the 
job.

KR>West System

[Colin]

I have used West System epoxy with great success for bonding large 
non-structural areas, such as the new wider shelf, overlaid over the original 
shelf and additional area.  It was much easier, and cheaper.  All structural 
components have received the T-88 treatment per Mark Langford's original 
recommendation to me back at the beginning of the summer.  It is not just good 
for like materials, but is excellent for mixed material applications, i.e.. 
wood & glass, wood & aluminum, etc.. provided one preps the 2 surfaces 
correctly.  For bonding AND reinforcing at the same time cotton flox using West 
epoxy, and cotton flox added to a moist paste works wonderfully.  It also gives 
great flexibility in the materials to be bonded.

[Ameet Savant]

KRnet,

Found this link on the West System epoxy. They mention
T-88 at the end of the article. Read and draw your own
conclusions.

KR>West system epoxy

[Rick Wilson]

One paragraph on the website mentioned, says that west
system epoxy in it's primary form is not an adhesive,
You make it into glue by adding fillers. It would
probably be excellent to use as glue when the right
fillers are mixed properly. I believe I will stick
with T-88 and not have to mix fillers every time I
want to glue a joint. Everyone is entitled to use
whatever they feel comfortable with. I guess in my
mind I've just never thought about using epoxy systems
for anything other than laying up fiberglass. Rick Wilson.
