Fiberglass & Epoxy #3, test run - testiranje ljepljenja

For a long time no news from me! It doesn't mean I wasn't working on my kite board, for example I've needed a quite some time to finally finish my vacuum pump before glassing my board!
The reason - vacuum advance device from an old carburetor wasn't working as expected. And to source another one in Perth is no mean feat.
Than, I've spent some time thinking how to glue the two layers of my board. The decision is to try first with a two peaces of exactly the same wood. Routed similar holes in it as well.
This is how it looks like:

Dosta je vremena proslo od zadnjeg clanka! No, ne znaci da nista nisam radio po pitanju izrade daske za kajtanje, vec je trebalo vise vremena da zavrsim vakumsku pumpu prije lijepljenja daske!

Razlog kasnjenja je neispravni vakumski dio od starog automobila koji je dosta tesko nabaviti ovdje gdje zivim.

Nakon toga, dosta sam razmisljao kako da zalijepim dva slojeva daske. Odlucio sam napraviti probu od dva komada istog materijala u kojima sam izradio slicne otvore.

Evo kako izgleda:

I will be using the most common epoxy for fiberglass  105A & 206B. This is my third epoxy product since already got the epoxy for gluing and epoxy for sealing. The expense now just for this three products is around $130AUD but hoping this will last for 3-4 boards. That is, if I'll make that many:)

The fiberglass cloth is  4oz and thinking to use 2-3 layers between plywood layers only in the middle of the board and under the footpads as well. Two layers diagonally at 45 degrees and one straight. Not sure if will be glassing both finished sides of the final product. Probably only top side anyway.

All of this might try on a test run. Hopefully, will go well!

Koristiti cu uobicajeni epoxi za fiberglass 105A i 206B. Ovo je treci epoxi proizvod koji sam kupio jer vec od prije imam epoxi samo za lijepljenje i epoxi za brtvljenje. Sve su to drugaciji proizvodi za drugu namjenu. Trosak za sva tri proizvoda je sada oko 130$Au, no nadam se da ce trajati za 3-4 daske. Ako ih toliko napravim:)

Fiberglass tkanina je 4oz tezine i razmisljam koristiti 2-3 sloja izmedju sperploce kroz sredinu daske i ispod vezova za istu. Dva sloja dijagonalno polozeni i jedan ravno. Nisam siguran da cu glasirati obje strane gotove daske. Najvjerovatnije samo jednu i to gornju stranu.
Sve to mogu isprobati na ovom uzorku. Drzim palceve!
