Build Thread Single Fin Shortboard + Funboard

I glued up two EPS Blanks yesterday. I’m going on a camper van trip with my girlfriend and two new boards will join us.

 

#1 will be a 6’2x20 1/2x2 1/2 32,5 Liter Single Fin shortboard for myself

#2 6’8x21 1/2x2 3/4 42 Liter Funboard for my girlfriend

 

Laminating schedule is still open. As I am pretty heavy footed I think I will go 2x6 top with patch in foot area/2x4 bottom. EPS is 25kg/m³ (I never know how to converse it…). Last time I used 3x4 top and still got a few dents after one week of surfing… Any ideas on the schedule?

 

Blank on top is the 6’8, under the 6’2 and the last one is a 5’5 shortboard out of the scratches that will be built when I’m in the mood.

Hello Parick, 25 kg/m^3 is just a little more than 1.5 PCF.

Thanks for the build thread, looking forward to it!

 

Google is great for unit conversion!

Back from 1 week of vacation and went in the shed again. I already forgot to take some pictures of glueing up the blanks and of board #1 after shaping as I just followed my routine…

Notes for myself. This was my first board with a stringer glue up. Normally I only do stringerless XPS boards. I didn’t work with a tolerance for thickness, that’s why some foam is “missing” close to the stringer… Lesson learned, but no problem as I don’t care about optical perfections.

The first board is already glassed with 2x4 bottom 3x4 deck. I really like the dark plywood stringer.



If finished weight is important to you, then maybe you can go with a lighter glass schedule by inlaying a denser foam under the feet. If you have access to Divinycell this would be a lightweight fix to dents…perhaps.

Finished weight is no point for me. I made one stringerless board 6’0x19x 2 1/2 out of this EPS with 3x4 top/2x4 bottom and it felt too light under my feet and bad in chop. So I planned this two to be a little heavier. I would love to try Divinycell, but at the moment I have no access to it.

Bottom on #2 glassed with 2x4oz and a freelap. And I laminated the top with 2x6oz with a 4oz patch in the foot area (I dented the first EPS board with 3x4 deck in a few sessions…). I’m happy with my first EPS tint job. Ways easier than on XPS.

Sorry for the bad lighting in my “laminating room” (loft in a block of flats in the city)
