I think if my fins floated they'd creat a shipping hazard

just got back from the Caroma factory tour in Sydney... i must say it was the most sophisticated setup i have ever seen (in the flesh) but strip away the multi-million dollar robots, CNC machines and epoxy pressure moulds and all you have left is the age old element of craft. great to see your work Decrepit.

Floats like a cork. It weighs 158 gm. I have a C3 Slingshot 23 that weight 468gm.

stringer i think the idea of custom fins are a one off product, pressure moulds are great for production but not practicable for the custom guys"" one mould =one fin" e,g you can have a bag of fins all the all the same length but different cord length and different foils, where as the guys using production fins have to stick with whats on the market, as soon as something new hits the market they have to fork out over $200 plus freight
where as custom guys can knock something up similar but better because it suits the conditions they sail and the equipment there using
after saying that , no i haven't tested my 26 to see if it floats , but one thing i do know is it's dam stiff for its weight

Keef I'm confident yours will float, but probably head down, unlike yoyo's and mine, your's hasn't got in the head.

Thanks for the pic yoyo, I tried them in a bucket, and the photo I took just looks like they could be wedged against the bucket side, they really want to float flat, not upright.

Quote: There are several methods of getting a thread in the fin, barrel bolts are probably the most common, but due to a severe shortage of barrel bolts, I'm trying two other methods.

Decrep. I have a milling machine at home you are welcome to use if you want to make some barrel bolts. Bring a six pack for us to drink and knock your self out and make as many as you want. I might have the tap as well.
As long as theres no wind forecast and I am not at work its available.

All my Techtonics Maui fins are tapped straight into the head material, this doesnt require barrel bolts and seems to be reliable.

When the core material is timber, that's not going to work.

I've got some fins I though were tapped into the core, but there's a brass insert of some sort hiding in there. They're molded fins and it looks like the inserts were part of the molding process.
