Here is the new thread for fthe fins i’m working on.
First , trying to find a good base to start : i cut cardboard template from MR 78 a just add some surface on the tip like Greenough fins.
Don’t be affraid of the cut, it’s just for verify that the fins goes on the fin panel !!!
First marine ply test ( from Zodiac boat ! )
It’s about 4,5 mm thick , very hard , before lam.
and the second multi wood panel : paulownia / samba / pinus maritimus
Note that the FCS tabs are in the hard wood , hope it’s help to resist !!
It’s about 6 mm thick panel, i think i’m gona reduce this to 2mm on tabs and 4 mm fins before foiling and laminating ( Epoxy )
For Mr FINS, thanks for help.
The idea was to make fins FCS, as i do some glasson marine ply fins, if i reduce wood to 1 mm and put 25 layers of glass it’s more a fiberglass fin as we can find cheap wood/glass china fins !
Foiling
before glassing
