Under the pump - Pod pritiskom

As promised (to myself:), today I laminated my bamboo kite board with a few layers of fiberglass. Used bi-ax 200g glass with 45 degrees layer in the middle overlapping the foot pads, two layers under the foot pads and one orthogonally layer for the whole board length. Used 180g (3:1 by volume or 3.5 by weight ), epoxy with the 403 West S. filler.
I was expecting to use much less epoxy however using a filler makes it more complicated to wet out. Will see when I'll glass the bottom with no filler how much epoxy will use.

Decided to use my new vacuum table which is efficient way to get the rocker. The concave is here as well, made with two 1mm balsa veneers and placed underneath. I think it was possible to place 20-30 cm wide fiberglass under at the same time to keep that concave in place. Maybe I will do that next time.

Kako obecah samome sebi, danas sam lijepio moju bambus dasku sa nekoliko slojeva fiberglasa. Koristio sam dvo-osni 200g fiberglas pod 45 stupnjeva u sredini preklapajuci mjesto za vezove, zatim dva sloja na mjestu za vezove i kompletan sloj po duzini. Utrosio 180g (3:1 epoksi volumno ili 3.5 po tezini), epoksija sa 403 West S. mikro granulama. Mislio sam da cu trebati znatno manje epoksija no koristeci mikro granule dosta je tesko navlaziti tkaninu. Vidjeti cu koliko ce trebati za dno daske bez tih granula.

Odlucih se za novi vakumski stol i efikasnu zakrivljenost. Konkava ispod daske je takodjer tu, na nacin da stavih dva slojeva balsa furnira od 1mm ispod daske. Mislim da sam mogao istovremeno staviti 20-30cm siroki fiberglas ispod daske tako da se zakrivljenost konkave zadrzi, mozda drugi puta i uradim tako.

It will take a few days to cure this super clear epoxy....

Trebati ce nekoliko dana da se ovaj specijalni super proziran epoksi osusi...

Getting there to my new kite board - jos malo do nove daske

Thanks to Matt and his idea for a new board!

 All the details and the design are in the Board Design page on the right hand side at the bottom of the page, B8 - WakeUP:

Hvala Matt na prijedlogu za novu dasku!

Detalje daske mozete pronaci na desnoj strani u dnu pod B8 - WakeUp:

My gut feeling is that this will be quite beautiful board:)

Hope you'll share my view!

First things first.

This time I was using the router with the attachment I've got with it. This attachment enables me to do an offset by moving bottom part by 1-2cm.

That way I can make a smaller or a bigger board with one single template! However, the catch is the template should be below the routed surface, not on top. This is not really easy to do, at least for the first time.

~

Duboko sam uvjeren da ce ovo biti prekrasna daska:)

Nadam se da cete dijeliti moje misljenje!

No, prvo najvaznije.

Ovaj sam puta koristio router uredjaj sa dodatkom koji je dosao sa uredjajem. Taj dodatak omogucava mi da pomicem router za 1-2 cm prem unutra ili van.

Tako da mogu napraviti manju ili vecu dasku samo sa jednom šablonom! No, postoji problem sa time i to je da šablona mora biti ispod povrsine koju radite, a ne iznad. To nije jednostavno, bar za prvi put.

The template is below my new board!
Tapered rails! Done with a belt sander in 10 minutes! After that drilled fin and footpad holes. Than poured epoxy into the rails. Used 60ml per side, 120ml all together. Epoxy 5:1, with red and orange pigment. Pigment ~5%.

~

šablona je ispod nove daske koju radim.
Obratite paznju za kosinu zlijeba! To je vodena strana! Kosina izradjena sa rotacionom smirgl masinom u 10 minuta. Nakon toga izbusene rupe za perajice i vezove za dasku. Sledeci korak epoksi ljepilo u zlijeb. Utrosio 60 ml epoksija za svaku stranu, sve skupa 120ml, epoksi 1:5 sa crvenim i narandjastim pigmentom. Pigment oko 5% tj, dva puta na vrh skalpela:) Od okativna metoda.

Remember my pre-made fin inserts? With 5 min epoxy and pre-made inserts all done in a jiffy...

~

Ovde dolazimo do unaprijed izradjenih drzaca za perajuce, ako se sjecate? Jednostavno sa 5 minutnim epoxijem i drzacima, sve napravljeno u tren oka...

Now it comes to the vacuum table! Still thinking if I'll do my standard vacuum method or will go with this:

Sada dolazi odluka oko vakumskog stola. Jos razmisljam da li da koristim moj standardni vakum stol ili ovo:

The above method is easy but no concave. Will run some tests and see...

~

Gornja metoda je jednostavna za dobiti zakrivljenost daske, no ne i konkavnost. Uraditi cu par proba pa odluciti...

Inserts test run - probni drzaci peraja

Fins inserts:

This is a second run. The middle insert was made first, didn't like the shape. This one is more what I'm after. But didn't like the color! It looks the same but it's not. Only middle one is a fluorescent orange, flash probably made it to look the same, see:

~

Ovo je drugi probni uzorak. Uzorak na sredini je prva proba, no nije dobar oblik. Ostali uzorci su noviji i oblik je u redu. No ne i boja. Izgleda isto no nije. Trebala bi biti flurescentna boja kao sto je srednji uzorak. To se vidi najbolje ba doljnjoj slici:

Now a third run...
