Resin question
Jack
fiberglass and plastic resin and then spar varnish. It will be stored out
of water and covered. Unfortunately, it probably want see a lot of action.
Could I use polyester resin rather than epoxy? Epoxy resin isn't readily
available in Fort Worth, Texas and I'm trying to keep costs down.

I'll need and I don't want to spend any more than I need to for a rowboat.

There is a West Marine in Dallas. You can use polyester resin, but the results
will not be as good as with epoxy, and eventually moisture will get between the
glass and the wood, since the polyester doesn't saturate into the wood, and
start you on the road to delamination and rot. If you are looking for a low
cost sealing system, have you considered Arabol and canvas? Cheap Cheap stuff,
buy it at plumbing supply shops, they use it for pipe lagging. Big bag of
powder, enough to do the deck of a 100' schooner cost $5and change 10 years
ago, doubt the price has changed much. It's made from milk and cleans up with
water, but once it sets up water doesn't hurt it. We used to seal all our wood
decks that way. It also remains a bit pliable and will work with the wood
rather than cracking and separating. It's not a structural system though, so
if your glass layer is there for strength, you're best off to go with epoxy.

I suggest you find a local boat builder to get your materials.

polyester and a small tube of MEKP will cost you about $30 delivered
from http://www,fgci.com. A gallon of 1:1 general purpose epoxy and
hardner will cost you about $40 delivered from the same place.
For ten bucks you end up with a MUCH better boat and you can use the
epoxy for everything. You also get a longer pot life and no stink.

prices of polyester and epoxy.
I put skids on the bottom instead of a keel. They do a better job of
protecting the bottom. I've also put on two coats of polyester without
cloth. The first coat goes on without catalyst and is left to soak in. The
second coat goes on with catalyst and takes a day to cure. The boats don't
get rough treatment.
It might be cheaper to use thicker plywood.

Windows?" You could start a riot. I spent two and a half hours last night
studying the archives and I'm not that much closer to making an informed
decision. If money was the only issue, very few of us would build a boat.
If polyester resin would do the job, I could get everything without driveing
more than 3 blocks. If not, I'll mailorder.

Epoxies such as West, System 3, MAS, etc. are designed for the job (building
boats with wood and fiberglass). While polyester may work for your purpose
(small boat, little use), it is not really the "proper tool."
Once you decide on epoxy, then you can REALLY get into the "riot mode" by asking
"Which one?"! The real answer is, "It really doesn't matter. Use the one you
can obtain most easily."
BTW, I'm a computer geek, too...

polyester resin. It's still going, some of it's looking shabby (but
that's because he never looked after it, and I've never got round to
smartening it up). From my experience, polyester will do the job. Btw,
Stevensons projects advocate using polyester and vynilester resins
rather than epoxy on their boats. That said, I work with epoxy because
I find it to be more flexible, so it's cheaper to bulk buy epoxy than
have two sets of tins!
To be honest with you, the best thing to do is try, if it doesn't work
out, then it doesn't work out... you don't want a work of art do you?

It appears to me that the over riding issue with you is cost.
If that is the case, forget about building a boat, any boat.
If that is not the case, get some epoxy and get on with life.
I know Ft Worth is sometimes referred to as a "Cow Town", but trust me,
there are epoxy distributors in the neighborhood. You may not like their
prices, but isn't that why mail order exists?

My experience is that fiberglass resin will not stick to plywood. I'll
be re-doing the forward Vee berth on my Clipper 26' as a "lessons
learned". Save your self a LOT of trouble and wasted time/money; use
epoxy.
All the best,

that it prevents or can accept the flex with no issues, then you should be
fine. Polyester doesn't bond to wood as well either, so you may find
yourself glassing the whole exterior instead of just the seams. Ask your
designer for help on his/her design and get their advice.
High quality epoxy at a reasonable price:
Fiberglass Coatings, Inc. (http://www.fgci.com). Ask for the 2:1
hardener/resin combo. If your shop is 60-65 F or warmer, then the FGCI
epoxy is fine for boat construction and only costs around $35/gallon of
mixed epoxy. They deliver. That should save you some bucks.

Marine paint with spruce or expterior plywood is fine (15 years)!!
Epoxy justs gives in another 5 years for 5 times the price. Polyester
Resin is fine too. Boatbuilders build epoxy but live on spruce/marin
paint boats.

produced plywood. It checks something awful. Especially marine fir and
spruce plywood is hard to find in most places. You end up with a much
better and longer lasting suface with a 2 or 3 oz glass cloth in epoxy
and then marine paint.
Besides, I believe you have your prices mixed up. A good quality marine
paing cost about 4 times as much per gallon as epoxy.

I don't have a clue what you are smoking but you could probably make a lot
of money with it, if you chose to do so.
No matter what you choose to do with wood, you can not escape the basics:
From compost it comes and to compost it shall return.
It is just a matter of time.
Brian
fir products and stick to the mahoganies (genuine or not.)
As far as prices go, marine paint and epoxy are about the same
price...pushing $90/gal. You can spend more on paint than on epoxy,
depending on what kind, e.g. $400/gal for some bottom paints. And you can
get epoxy suitable for boat building (quality) for as little as $35/gal too.
....2:1 epoxy at FGCI, http://www.fgci.com
