For Me this IOM looks to be an evolution in Design (Good or Bad??) and it is Distinctly

"KANTUN" like...
I totally agree we have a Chienz and a BP here that sit side by side in the club and i can't say they look alike.We've got a new Lintel arriving for next weekend's regatta to spice up everything.At least the fleet is getting hotter for shure with another 4 boats on order,i'll see if i can get some pics of these 2 side by side this weekend.[/QUOTE]

(1)put boat upsidedown on table vasiline the shaft hole.
(2)get wifes cling film wrap and stretch it on there so theres no wrinkles in the rudder area.
(3)apply filler to top of rudder
(4)insert shaft into hole
(5)send it down until filler makes contact with cling film wrap.
(6)let it dry for 2-3 hours and remove it
(7)sand it,therefore you use only a small amount of filler.dead easy
Tug,
Yes, I want to do this mold work to close the gap to the Hull... But:

In the model aircraft world we use "Micro-Baloons" or Milled Fiberglass in a slurry with Epoxy as a filler:

http://www.amazon.com/Great-Planes-M...ref=pd_sim_t_2

You are suggesting use a different type of filler I've never heard of.. can you tell me what it's called, who makes it, and ideally where to order a small amount of it? I have bondo and it's catalyst .. it's pretty thick and it has embedded Fiberglas strands in it as well ( making it harder to work with in a small project like this is).. but I'm afraid it, and the other materials I have won't gel firm enough to hold up while it dries against the mold very well, so it likely won't hold the shape needed at the top of the fin flat surface or result in the anything close to the correct shape as it melts down and dries on the covered hull.

Wouldn't it be better to just pull the rudder, use two strips of 2 inch painters masking tape on either side of the fin to make a 1/2 inch pocket I can fill with 1/4 inch of filler and then once dried.. peel off the tape, and then manually sand and shape the contour to the hull later?.. that way there will be minimal to no "shaping" needed at the black/ flat edges of the current fin? If i had some of you filler to test it's viscosity, or experience with it I'd likely feel different Thanks Again.. JimS

Does anyone know where to get updates for the European Championships, other than their website which doesn't appear to have a location for pictures or updates.

Micro ballons work just fine but i mix it with west system epoxy this stuff is really strong mix it until it cannot drop off of the stirstick as a liquid,you should be able to get that at west marine -boat US stores in a small quantity,i suggest doing it the way i said just don't put on heaps and what comes out sideways will be easily water sanded using a sanding block,this could be anything flat with sandpaper on it i use a piece of plywood and then go to a very fine paper the top part that went on to the cling film will be a perfect fit.Maskin tape is going to distort in shape and sanding the top you'll get close but not perfect therefore in the end you have neither surface correct.Don't freak i've done this more than once and it's so easy.

Here is something provided by Gougeon Brothers (makers of WEST System epoxies and hardeners) for mixing really small amounts of epoxy - and without a lot of measuring, weighing and the need for a scale. Because WEST must be mixed in a ratio of 5:1 (resin to hardener) one pump from a quart of resin and one pump from a pint of hardener will produce enough resin to provide coverage of a 1 meter hull, you will waste a lot of epoxy and the still is relatively expensive. (That said I would use nothing else). Oh - be sure to buy a pump for each size of can - and remember - the pumps measure 5:1 for each full pump stroke. DO NOT press resin pump five (5) times or your finished mix will wind up like chewing gum!

Print out the attachment, cover with wax paper, and fill each circle with the resin (big circle) and hardener (small circle) and then mix well. AFTER mixing, keep adding your filler of choice to make the mix thicker and less runny. The attachment contains a bit of theory behind using the circle - and you can enlarge or reduce on a copier to meet your needs.

Good luck with the project. Dick
