I decided to give a go at building a IOM fin for my boats.
here is the process I opted for:
build the cheecks of the fin in 1 layer of c/f 200g + 1 layer of f/g 50g - done that on a flat plank covered of magic cooking sheet (brilliant for cooking and even better for doing flat laminate :rolleyes:) epoxied together using West Epoxy 105+205
for a consistent thickness and adding longitudinal strength I tack together 2 pultruded c/f tubes of 5mmx3mm
to make the leading edge thicker I epoxied together 4 layers of 200g c/f out cuts which I epoxy on the leading edge of the fin
epoxy the whole lot together using thickened epoxy with 406 up to a peanut butter consistency
And because this morning the weather is brilliant over here - 18-20C I decided to to glue it together.
and now I cross my finger that my time in building this prototype fin will work !!!
any feedback, views and suggestions welcome
