Re: 24 hr epoxy cured in 1 hr

Also, a more hardener than recommended can decrease cure time. Not sure if that's recommended. Epoxy cross-links, so excess hardener doesn't get used, which is why it's recommended to be very precise with the ratios. Polyester systems however has an activator, and the amount of activator can speed ...

Re: Board width + boots size?

With boots you have a lot more leverage, so you can go wider with the board than with straps.

Re: foilboard core materials and physics

Stiffness is mostly determined by the thickness of the sandwich, but the elastic modulus of the reinforcement (carbon/glass) plays a large role too. Generally the core needs to withstand compression and shear forces. Typically the more dense the core is, the more compression it can handle without de...

Re: Gojoe

The main reason for this is apart from the yellow fins the whole base is black and I lose sight of the board easily. May seem obvious but it works: Simply spray paint the bottom of your board a bright colour. I've done this on one of my carbon boards (with straps) because they are notoriously diffi...

Re: Cape Town - Blouberg/Big Bay Tips

When I go to Cape Town I rent 2 cars. One for the family and one for me.
Then you can stay anywhere in the area, and go kite anywhere.
Langebaan and Shark Bay is definitely worth a visit.

Re: Core kites and kiteboarding industry sales this year

I also wonder about the sales numbers mentioned. 25-35 k is a big span...if they knew numbers it wouldn’t have that span...so it is just an estimation. The GKA should have better numbers, since they have the biggest brands organized and they for sure know precisely how many kites they sold. The sam...

Re: Core kites and kiteboarding industry sales this year

For those who haven't yet read it, check out issue 70 of iksurfmag, where they have an industry-focused article. Apparently the following numbers are indicative of the market for 2017: Total number of kites sold : between 140,000 and 150,000 Total kites sold by Cabrinha : between 25,000 and 35,000 T...

Re: Info need on kite bar

At 0:35 in the video they mention that the override is an optional accessory item. Maybe your bar is just fine without it? So the override and the ring are option and we can use it without those part? I've got access to the same information as you. You say your bar is missing parts. The video says ...

Re: Info need on kite bar

Maybe post a picture of your bar? If you are lucky it may require only a small fix. Alternatively you need to find out what type of bar you need for your kites before going to market. Some bars are designed to work with equal length kite lines, others not. Some bars have a low V split and others a h...
