: Hi Ian, my build also suffered from a slow period due to my
: wedding. I vertually took from the middle of June till now to
: get started again.
: I have gottten a hold of some walnut and lyptus so I am working on
: a deck lay out now that is going slowly due to too many
: decisions on the look I want, but I plan on posting a pic or two
: as soon as I have the deck lay out done. I have chosen a wavy
: lay out with two strips of pine wrapped in a quarter inch piece
: of lyptus bordered by a quarter inch piece of walnut, with a
: walnut center strip also a quarter. The cockpit cutout will also
: mirror this, with the rim of the cock pit being walnut as well
: as the stems.
: Stems are not in place yet either.

: What glass layup did you do? And more to the point how much epoxy
: have you used and what do you figure it will take. I plan on
: using thayercrafts 3.2 oz. , 40x40 cloth, and silvertip epoxy,
: finished in autoclear.

: An earthquake, where do you live?

: All the best,

Hi Dave

Congratulations on the wedding, that is a good excuse to delay! We moved house and our new house has no garage, so I have to travel to work on it now. Not too far (15min each way) but makes it hard to do a little here and a little there.

We're in Christchurch, New Zealand. 7.1 magnitude earthquake here last weekend. A lot of infrastructure damage and quite a lot of mostly superficial damage to older masonry buildings. But no loss of life fortunately.

The Haiti earthquake was basically the same as the Haiti earthquake that levelled Port au Prince and killed 200,000 - same magnitude, proximity to the city and depth. Fortunately we live in a first-world city with a far lower population density, earthquake building regulations, and it occurred before dawn on a Saturday morning.

Your questions:
* Layup: I used plain 6oz glass. 4oz is nearly twice the price here. I made the stupid mistake of putting a 3" tape along the keel *under* the main layer of cloth, despite having read advice to the contrary many times. I was nervous about using the full layer of cloth on my first attempt, but too impatient to test on scraps, and in my haste didn't think of the consequence of using the tape under the main layer. Still it's just a line and a soft ridge along the keel, and it's on the hull so not really noticeable, and part of the story now.

I only used one layer of 6oz, plus the tape. Most advice I have read says to use a double layer on the hull below the chine. I didn't bother this time around because I'm not expecting to run up on stony beaches and well maybe I'll regret not doing it later. We'll see. But by golly having 6oz inside and out makes the hull incredibly stiff.

I used West 105 resin and 207 hardener. I bought a 4 litre (1 US gallon) pack of the resin. It's almost all gone having glassed the hull inside and out, and the deck outside. So I'm going to need more for the deck inside and remaining epoxy work. If I had used a squeegee instead of rollers I am sure that would have saved a lot of resin, hate to think how much has been thrown out. For the deck inside I'll use the standard 206 hardener since it's not such a big deal to get a clear finish and it's a lot cheaper than the 207.
