Thread: Paulonia Experiment

Lewy,

The boat's looking terrific, and if it makes you feel any better, I have shared your pain, but I think it's due to the high humidity we've had these past few weeks. Yep, I do measure humidity in my workshop!

I've been very leery of epoxying at all over the last two weeks because the humidity has been in the high 90% range the whole time often 100, and it doesn't get any more humid than that inside !

I've had the same problem with West at around 98% humidity, but eventually gave up waiting to build the rowboat and had a crack anyway. (See my rowboat thread)

Using BoatCote the humidity in my shed throughout the day ranged from 97-100%, and I had the devil's own job with outgassing (not the epoxy's fault!) then on the final coat wet on wet, with milkyness due to humidity. I think this was due mostly to air entrapment from the roller, so kept the coat as thin as possible, and most of it dissipated while the epoxy cured.

I'd certainly put it down to extreme humidity. I wouldn't varnish over 90%, so expect a similar reaction with epoxy.

I'd like to hear some real numbers from others, but that's my experience.

cheers,

Just a couple of more pictures of progress. The aireal view was taken
friday night. Its been a big weekend the motor is now on and its going in the water next sunday. For those that have asked it now weighs 180kg minus the motor of course. The deck is 4mm ply overlayed with 4mm of Kwila with hoop inlays, then with a layer of 200gsm glass and coated with about 10 coats of Sayerlack, finish is like a grand piano.

Regards

Great looking boat Lewy, I can't wait to see the pics of her at full song!

What was the outcome with the cloudy epoxy?

That is a brilliant looking boat. I am thinking it would be just the bees knees for Bream fishing although if you were making the boat for comp use you would have a different deck on it so as to have casting platforms at the gunwhales stern and prow. Not to mention a fixture for an electric motor at the bow.

Very impressive makes me think about getting onto boatmik or someone for some drawings and see if I can do something similar.

lewy mate... you should set up a competition fishing team using the boat & sponsor it from the business...... the whole thig could be tax deductable

cheers

Nice work Lewy, you should be real proud of the outcome.

How did you go with the ABP and registration?

Great Job Lewy
been watching the thread from the first post
you've done a fantastic job.
be keen to hear how she goes on the water also
cheers

The cloudy epoxy. We sanded it back to bare timber and did it again this time the humidity was around 60%. It was better but not great. Boat craft said that this can happen with thick resin, the cloth was 200gsm we were careful ti sqeegy it thin and even then applied peel ply. A blind man would pleased to see it.

Rego and ABP.
Its registered but has not got a ABP, the transport department said they would send the info to Maritime Saftey, dont no what happens know its been registered for at least a month and still no word. The authorities seem as confused as us.
