Vacuum quick release - vakumski ventil

What to say after a while? :) Well, for a start, the kite surfing season just finished for me. Managed to learn some new tricks, not much though. It was an unusual season with only 20 or so sessions on the water:( Also managed to break my hand made board. Sort of. It didn't really break. It's just a tiny crack from a side to side under my foot and needs fixing. This happened after a Jump. And this Jump was not for heart fainted. At a middle of it, I was thinking that will flew over the trees. Not at, or trough, but over 15-20m tall trees:( In a split second decided to land before the trees, to avoid becoming a something like Christmas tree decoration:) Landed dead flat and the board snapped. Of course, it snapped because the bottom of the board was not fiber glassed. Didn't have a time to do so, holidays coming etc. Now we will concentrate how to, hopefully, fix it! But first, I need a better vacuum connector, or a quick release. Coz, I'll glue some Bamboo veneer to my board in a vacuum bag.

 Sto da se kaze nakon toliko vremena? :) Za pocetak, kite surfing sezona je zavrsila za mene. Protekle sezone naucio sam par trikova, nista posebno. Sezona je bila losa, uspio sam biti svega 20-tak puta na vodi:( No, uspio sam slomiti moju dasku. Ne skroz. Nije slomljena do kraja. Nekako je samo lagano napukla sa jedne strane na drugu tocno ispod vezova i potrebno ju je popraviti. Desilo se to nakon sto sam skocio. No, to je bio skok za pamcenje. Usred skoka, mislio sam da cu jednostavno preletjeti obliznja stabla. Ne zabiti se u njih ili sletjeti na iste, nego preletjeti preko 15-20m visokih stabala. U djelicu sekunde odlucio sam sletjeti prije nego postadoh Bozicna dekoracija:) Sletih sa totalno rvnom daskom i u tom je trenu napukla. Naravno, napukla je jer nisam stavio fiberglass na doljnju povrsinu daske. Nije jednostavno bilo vremena, problizavali se praznici i to je to. Sada cu se koncentrirati na popravak, nadam se uspjesno! No prvo, potreban mi je bolji vakumski ventil za vakumsku vrecu. Jer cemo lijepiti bambus furnir na dasku u vakumskoj vreci.

The above are the parts from my "enhanced" vacuum connector. The main part is Check valve! Last but not the least some Perspex with a hole to connect Check valve and some channels at the bottom for air evacuation. How does it work? I always try things before "production" usage:)

 Na gornjoj slici su svi porebni dijelovi za moj "redizajniran" vakumski ventil ili konektor. Najvazniji dio je "jednosmjeran" ventil, ne znam Hrvatski naziv, sorry. Drugi isto tako vazan dio je komad plexiglasa sa rupom za ventil i par kanala na dnu plastike za evakuiranje zraka. I kako to sve radi? Uvijek probam stvari prije "pravog" koristenja:)

The above photo says everything! After 2 hr, vacuum was still holding. The slightly raised  area around stainless steel nut is Blue Tak to keep everything air tight!
All of the above for this:

Gornja slika sve govori! Dva sata nakon sto je vrecica vakumirana, vakum jos drzi. Malo uzdignuta povrsina oko matice od nehrdj. zeljeza je "plastelin" tj. ljepljiva masa koja drzi sve "zabrtvljeno"!
A sve to da bih dobio ovo:

On the side left with a piece of lace is the vacuum connector, vacuum holding for 10 hours! Stay tuned...

Na slici lijevo je vakumski konektor spojen sa spagom, vakum drzi 10 sati! Nastavljamo...
