Im not anti epoxy or any other material,the points you make also apply to any other product including epoxy?
I think Patrick means with epoxy you only use that stuff once, where with oiling you would be using that stuff many times over the years.

Having the super sap shipped from where ever it comes from in the usa, to spain and then to me is not very eco :oops:

local sheep lanolin would be the best eco I think.

now you're talking - lanolin protects and seals the timber. But paulownia is very durable and waterproof in saltwater anyway. - Lanolin also has the added bonus of going sticky in salt water - no wax. Find a wool scourer, ask for a bottle of raw lanolin, they'll give it away. Industrial lubrication. Lots of places to find it, you're in Wales rub it on a sheep :D
Another thing about the "eco" thing - all good. But a board built using timber, be that chambered,hws or a timber planked foam substrate, will (or should) last a hell of a lot longer than its foam / glass counterpart (baring any real disasters) so in my eyes a board that lasts a long old time - no matter what its made of is way more "eco" than one made from chewed hemp stems and sealed with boiled shark crap (sustainably harvested of course!) that falls to bits after five minutes - even though its essence will nourish the plankton.
sorry must have missed my pills this morning :twisted:

Karuhi,

I was wondering if you got waves from Pam? Also, did you pick up your wood board?

Bob

Sorry to crash your thread Krusher,
Hi Bob. had a quick standup play on Pam, but to tell the truth she was a bit of a disappointment up here in the far north. came through very quickly and didn't get a hell of a lot of play time. I sort of blew it and went to the wrong place. Its also on the opposite coast to me too - but that is only an hours drive.
always making wooden boards, had an alternative board day last weekend so I'd been madly trying to finish a timber board (standup), i did however also take along a paipo as well. Still haven't made myself a timber paipo, only have the one i did the thread on, and another with a 2" agave stringer down the middle and tail blocks. Which is the one i use most of the time. But i have a chunk of foam half shaped that I'm going to wrap some timber around for a paipo.
Hi Matt - yes we have paulownia here, i use it about 50% of the time. there is alternatives nearly as good.

Got back on it as it needs finishing before my SA trip!

finish sanded/shaped it today and took it to my friend for him to apply the epoxy.

Bit worried that a few joints did not glue up to well as the final shape was hard to clamp together (another $100+ of clamps to buy for next time.) :oops:

Phone quick pics so not great, will try to show the shape better when its finished

Does it have resonance?

It had a lot up until the solid rails were glues on, I guess the air chamber is now sealed so would need a hole like an acoustic guitar to resonate again :?

I forgot to weight it before i gave it to my friend, seemed plenty light enough under arm though.

You can maybe see it in a little over a week, looks like a good SE swell is going to head up the east SA coast, does that look good for durban?

Looking good...

Karuhi...what are these paulownia alternatives?

The east coast is at its best around this time of year, light off shore winds most mornings in between the south westerly storms ,with19 to 20deg water be free from your wetsuit, bring rash vests and plenty sun block remember your elbows without your wet suit padding.SE swell with SW winds works well .

I think two coats of epoxy is the safest way to start. That way you have a Plan B if it cracks along the grain...you can put on a layer of 4 oz. glass as a fix.

I remember John Mellor snapping a surfboard that had a chambered stringer. It was 1 inch chambered redwood capped on either side with unchambered 1/8 inch cedar. His inside corners were sharp 90 degree. That's where it failed. You'd think the weakest part should be at the middle of the span over the chamber, and maybe sometimes it is. But where the pillar meets thinner wood at the corner of the chamber can be a hinge point where the wood flexes differently. That was the campfire theory at least.

I just got my board back tonight, little wet and dry to polish it up a bit and I will get some nice pics taken, in contast to that 10kg 22lb beast, mine has come out at 7.5lbs and feels really strong. :D

Well took the board on my trip to J-bay a few months back and had its maiden voyage there, it works!! :D

The float is very nice and it glides through he water well with the hull entry. Pretty easy to catch waves on.

its functional and rides well off the tail. :D
