Peter, everything is clear in your videos is just that for a newbie that never played with époxy and vacuum bagging before, it's a lot of info in a short period of time...
As promised, find attached pictures of my first board for which is based on my Cabrinha custom 135 (2010 if I am not mistaken but time goes by too fast for me to remember exactly which year exaclty is the model I have
)...
If you look carefully, you will notice, on the bottom of it, that the fiberglass cloth is visible and I was wondering if it was because too little epoxy was used or because the plexiglass was not 100% smooth (the previous owner did at least a board with it and there was some residue that I didn't removed prior to vacuum bagging mine...). Any words of wisdom on this?!?
Also, there is some corecell that is visible on the bottom left along the rail but that's another story (as I cut my fiberglass cloth too close of the board and the corecell probably moved during the process and/or when I started to vacuum bag the board...)
Finally, the board is way too flex (like foam-n-fibre warned me...) and it is also surprisingly light (don't have a balance to weight it accurately but it is very light, way more than my Cabrinha Custom... I used T600 10.5 mm corecell, only tapered the tips to approx 6 mm and put 3 layers of e-glass on each side but it is quite flex in the middle of the board. What is the best way to get one more stiff??? Should I use Kevlar and/or more fiberglass cloth, a wood core, or anything else... Keep in mind, if you have any suggestion, that I am on a budget given the fact that I have access to fiberglass cloth and kevlar for free so number of layer doesn't matter even though total weight does matter... I honestly don't know what to do here...
P.S. I will let you know once I tried it on water but compared to my other Cabrinha boards (Custom, Rival and Caliber) I bought, it seems way too flex for kiteboading...
