Love seeing Owl Greg. Glad he’s still Owl. One of a kind. Tell him I said hi.
Still one of the biggest characters on the North Shore.
Hi Greg,
Thank you for doing this.
This Shapers hot seat is great!
I am building hollow wood boards, and am using your resins.
I am sealing the inside before closing them up, but un thickened epoxy is quite heavy.and you can’t squeegee the excess off all the insides like a flat panel.
My question is,can I thin the resin to go on much thinner and perhaps penetrate the wood somewhat.
What type thinner and how much can be used?Or would another product be better.
I’ve heard of that Smiths penetrating resin, which sounds OK in the descriptions I read.
One option I considered for light weight, is spraying some kind of water based polyurethane before closing up the board.
Since I’m using Resin Research epoxy for everything else, I just wondered if it could be thinned for that use as well.
On the subject of thinning resin, can you thin it with denatured alchohol or something when laminating to use less resin?
If so, how much could you thin it.?Or is it a bad idea?
I’m just trying to think of ways to shave a bit off the glass jobs on these already heavier woodies.
Greg I have met that guy from Tampa with his catamaran SUP. He wins a lot of open races on that thing. He has been rather closed mouth on who shaped it. I thought maybe it was a home build.
He is now building a Catamaran Fish sup but the design is all wrong stable but needs more float in the front. I have been working on my own design. My thinking is that cat SUP tunnel hulls are the way to go for flat water.
Should have put the above as a question. As to your thoughts on SUP design?
Artz, not me on the SUP cat. GL shaped that hull for me a few years ago. 18 feet by 16 inches and it was perfect to my eye.
Hi Greg,
Just curious, are there any prospects with regard to UV cure epoxy?
Thanks,
Andrew
they should now build a tri hull’’ and they will find just how much better it will be than a twin.
cheers huie
Video was taken 10 minutes from my house :-)
doh! missed you at the show. so, an easy one. the addF i got from sam a year or so back? how long do I keep it? I’m getting ready to do a coupla compsands this summer. love your travel pics. glad to see your knees are working well.
Hi Laslo, thin t he resin with about 20% xylene. Maybe try one of those small foam rollers, I was always able to get the resin really thin with those. Let the resin breathe for a couple days after to let the xylene leave.
Hi Artz, SUP design is interesting as far as race boards go because they are true displacement hulls. As such the narrower and longer you go the faster the board will paddle. It’s a hull speed issue. I’ve paddled with racers on the same size equipment and in a mile long race they’d beat me by a couple lengths (I’m no racer). It takes some serious horse power to get a displacement hull to run faster than the following wave you’ve created. If your in a class race pretty much the winner will be the one with the narrowest board. Racing in unlimited takes a real gorilla to push that much board especially if there’s wind. All this stuff already happened in kayaks and as the kids grew up on narrower equipment they began dominating. So they finally classed all the measurements.
Thanks Greg, nice links.
Hi Newschool, I’ve worked on UV epoxies, I’ve had numerous samples. The problem is that the epoxy oligimers need a very broad spectrum UV. The lighting systems cost upwards 100K. Not many shops could swing that. There’s some other high solids options out there but the results are pretty cheesy for board building. Boards require high end physicals.
Hi Pompano, good to see you again. Add F doesn’t last forever and the only way to know is to test it. Yes the knees are good and the travel photography has been fun.
Hey Greg i think you are the only one that can answer me on this one: sometimes when im glassing PU With Kwick kick i get a yellowish spot were i put extra patches(fins patches,decals, etc.)
What is the reason for that? What should i do?
