I'm not sure how big or small these templates are appearing on people's screens there , but on mine , they are not actual size ....
the sizes they are appearing for me are actually almost big enough to use as medium size twin fins ...like a 4 3/4 " base , 5 and a bit " depth , on some of the templates...so , obviously , if you find the dimensions I mentioned on the cardboard templates too big , the " screen size" version you're seeing may be a more practical / better option .....
just my thoughts .....
4 3/4" base , 5" depth .....
[and , as a "funky" negative print ....]
chip when you make these templates do you compensate for glass overlap over the edges of the fins?
I've done this a few times, taken lots of time to get them perfect and then forget I'm going to bulk them up with glass...
do you have a certan amount of glass overlap everytime?
hi "deathfrog " !
Okay, this is on wood or foam core fins .....
.....I tape off one side , and glass the other .
Then do the other side *.
There is a "halo" of excess glass as a border to the fin , which I sand to very close to the fin's outline . [I don't use the rovings method I have read about here , although that also sounds good for keeping the fin's edge[s] watertight.]
* So, I don't "lap" the cloth , as you would with a rail .
hope this helps !
well that's kinda what I ment with better wording.
The 'halo' of glass, like on your sharky fins with fish fabric, did you plan to have that much or did it just end up that way?
ah yes ...good question ...it WOULD look like a "halo" , of course ...hadn't thought of that .
No, 'Deathy' , that is actually an ALL fibreglass fin . [I only get a "halo" / glass border , with wood core fins]
What happened with the fish fabric inlay fin you saw is ....
.....I put the fabric too far "outside ' [if that makes sense] , when laying up the fin . [D'oh !] So , because it was amongst the OUTER layers of cloth , it got grinded when I foiled the fin .
Live and learn eh ?
....on my next fibreglass keels , if I DO go with a fabric inlay , I will place it about 5 layers in [from the inside edge of the fin ] when laying it up....
thanks for asking mate !
