Thanks for the photo Paul, The hardest part on the fin I rebased this morning was getting the forward projection right so it forms a good seal on the bottom
of the board..now I know how you do it ..flat plate of glass :-)) cleaver
That's actually just to get the 2mm of black silicone to sit flush with the board, but I do use it with some wet and dry to make sure it's level.
After the test run today I'm convinced that it's the best weedie I've used, and with a few minor tweaks it will gybe a lot tighter (the fin maybe, not me). I need to move it forward about 1cm, maybe 2?? So I can get the centre of effort in line with the rear footstrap.
Now I wonder where I can get some carbon laminated g10 !?
Very nice Keef, is the carbon laminated over g10?
Took me a while to get the foil right and I couldn't use the traditional eppler or naca foil as they're about 9-10 percent. So my foil was done by eye. And alcoholic ginger beer 
pepe i sent you a pm this morrning , well i thought i did , if i didnt let me know
Fin looks great up close paul, unfortunately mine was less successful tho' I did get to pip you with a 29. (after Decrep and Dot left the wind came in nicely for an hour or so of constant planing). But the mod I made to mine seemed to make it worse. It wouldn't point , felt slow and I still went over the front hitting a patch of weed 50m south of the rock garden posts. Back to the drawing board.
I think you may have hit on the perfect shape for the estuary.
After a fair bit of R&D the fin was retrimmed and laminated with carbon, but it seems to resemble Tim Hemer's "Tomahawk", honestly Tim it just turned out that way
30 cm, 434 sq cm and 43 deg. Around 9 percent, I theenk. profile guage? nup!
Carbon laminated over polyester.
pepe looks great 43 & 9 percent should be good from 7 to 8 1/2 , hey your stubbie holder looks a bit dry
Nah , that's just an illusion. He took the photo on the way to the fridge for another one. :-))
I was going to do the responsible thing and wait until at least midday,...but what time is it there Keef?
Was expecting some shrinkage due to some warm weather but found that, despite warnings to the contrary, 9.5 mils of hardener instead of 10 in 50 mils of resin, slowed the curing process enough to stop it happening. Chalk one up for experimentation.
Hey Hards, with a polyester core mine probably take about a week to make, weighs nearly a metric tonne and is not financially viable. But it would make a great anchor for a 5m runabout. My money is going to be on Tim Hemer's Tomahawk. Check out whitelionwindsurfing, the ideal estuary and Australind fin. BTW,
I'm not getting paid for this!! 
Not sure what's happening here. Tested out the fin which goes well, until you try and throw it into a gybe. Then things get interesting, board wants to keep going, or spin out in the opposite direction. May have too much area around the tip of the fin. Or the cut-out is not profiled thin enough. More testing needed. 
Wondering now whether when the board is transitioning through the gybe the lift is transferred to the other side of the fin, giving it lift and thereby throwing the whole process on it's head. I wonder if the thickness of the fin could do this?
Pepe, what do you mean by spinning out in the opposite direction?????
If you're doing a carve gybe, with the sail in neutral, the main force on the fin is to the outside of the turn.
Sounds a bit like there's a fight going on between the sail and the fin, maybe you have to change your technique a bit????
2 things slowing the fin down at the moment. Leading edge is blunt as a bowling ball and the chord near the tip is (was) about 12 percent. Like driving with the handbrake on. See what happens today 
Tested out the reprofiled fin today, and noticed the difference on the first gybe. Admittedly not the fastest of gybes due to the lack of wind but felt a huge improvement immediately. Big thanks to Stroppo for bringing it to my attention, would have wound up in the confused fins bin otherwise.
