who want's a sandwich ?

Spent some time at work this week-end, the first half hull mold is well on it's way and I did my first sandwich test with the rohacell and glassfiber just to pick-up the trick. I definitly need some more practice... and different foam. I did a little review to compare as you can see.

I didn't find an other way to answer the posts, so I'll do it here. I intend to build foils too as that's he most interesting part, but I've got a lot to learn till then...

Next steps : sandwich sample test 2 ; order new foam (maybe 2 different) and some carbone fiber ; finish first hull mold.

See ya.

Thanks !

Hey ! Thanks for your posts, all very useful advice that I'm studying now. Really honoured to be part of the moth community, might win my wings soon ! My working pace is maybe a bit slower as some of you as I haven't planned any vacation for this (thicking about it though). It might just take some time before I start thinking of the foils for example... aber wäre eine gute Idee.

I would like to thank all my former colleages of Firbourg for contributing to my boat project. It is definitly very usefull ! I just bought my first load of stuff from the local composite retailer and hell it's expensive.
On this week's skedule there's finishing the frame of the hull mold and doing a first test of a flat sandwich plate (with a leftover of glass fiber). I chose to copy the half hull method of the amercans on youtube (see previous link).
The test foam I bought is 5mm Rohacell 51, but it much too stiff, not at all what I expected. I'll try Soteco next, it only comes in 6mm thickness, but that'll do. It's supposed to be more flexible and it's also available partly sliced (pic) for really sharp curves.

I can heat the workshop up to 15-20°C as long as it doesn't freeze outside, hope that'll do for the fast epoxy I bought (15min working time). I also took a slower one with 90 minutes working time, thtat will definitly need curing ; I might need to do a test at the car body shop next door which has a 60°C oven.
Well I'll try and get some pics for next week to make this look a bit better. Thank's for reading !
