Blocoloco’s efoil

blocoloco · February 6, 2018, 7:46pm

i’m going to build the board from scratch. first i did a testcut of a board in the size of 30%.

the second step was a testcut with old eps material, to see the dimension.

last weekend i’ve done the finalcut. i’ve changed the dimensions it’s now around 70cm width. still a long way to finish…

a little motivation photo for the next steps. it’s not the fix position oft the mast, just placed the board for the picture.

the mast should be ~12" from the aft edge of the board. This is the typical mount position for kite/surf/sup foils

thanks for the adive, this will be the next step

did some progress today…

i’ve done a testmount for the mast, to see if it’s strong enough.

Nice! Please let me know the results.I’m looking at doing the same install.

blocoloco · February 11, 2018, 9:00am

i’ve tested after 24h waiting. it looks like i’m on the right path.

blocoloco · February 12, 2018, 8:35pm

today i’ve cuted the channels on the board. i’m happy with the result.

Very nice. Where did you source the block of foam from? What type of foam is it?

Thanks.

blocoloco · February 13, 2018, 7:03am

thank you…i’ve ordered in this online-store http://www.iceblanks.com/de/

My only concern would be that when you mount the channels, you normally do it in a higher density foam as it provides more strength. That is why some companies sell the high density block kits.

blocoloco · February 13, 2018, 9:42am

yes me too, we will see if it’s strong enough

blocoloco · February 17, 2018, 7:01pm

after the test i’ve changed the stringers. every stringer ends with an angel now, it’should not break wehere there stringers ends and i’m using good wood in aviatic quality. next part is to set the mount boxes and cut out the box for the stuff.

g.gregory8 · February 17, 2018, 7:27pm

Nice detailed photos. Is there a reason not to make the stringers wider/deeper?
Did the stringers fail in your test near the ends?

blocoloco · February 17, 2018, 7:43pm

the test was fine, but then i pushed with hole bodyweight against the 1m mast and it’s broken at the end of the wood. i think it would not happen, if there is already glassing, but better to build it a bit stronger. i can’t go deeper, because the hole stuff will fit in the board. on the top are two stringers which are working against the bottom stringer. i’m not a expert, but it look strong enough to me. fingers crossed

I got similar rail and once glued into the hi density closed cell foam I realized that mounring the mast only using the central slot it’s a pity! So my suggestion is to open another slot at back end of the rails. For experience in kitefoil, xps is enough to resist the pressure, stringers are a little overkill and add weight but allows for lighter glassing

blocoloco · February 18, 2018, 11:48am

the stringers are more about the big hole in the deck, which i’ve cut for the accu and remote stuff.
