Pintle and gudgeon sources

Re: Pintle and gudgeon sources

Patterns can also be 3D printed, which is neat because the slicing software can add the scale for the metal shrinking as it cools.
I did a masthead for the kid that way out of aluminum.
Ken, do you have an initial design to share as pictures?

I really don't yet. I have some left over 1/2 " ply that I used to laminate my centerboard. While I suspect that it might be a little too light-weight for the cheeks by itself, I thought I could double it and that would be plenty stout. That plus the beginning rudder thickness of an inch, and we're looking at just a smidge under 3". So nothing's in concrete yet, just looking at my options.

One can make them of epoxy and fiberglass
i think its the future

Me too

O.K., here I thought that you guys were being sarcastic. So tell me more...

Sorry Ken, I didn't mean to take this off track; your post said you were looking for bronze so my reply was probably not helpful. I don't know what size you are looking for but if it's for something small, the Springfield Fan Centerboard Company might be another place to check.

No problem, I was seriously unaware there was such a thing as epoxy and fiberglass. I was curious as to how there're made. Can you add color to it as needed? Interesting...

Re: Pintle and gudgeon sources

I've been experimenting with making sailing canoe hardware from carbon fiber, partly because it's hard to find in bronze, but more so to avoid the need for metal fastenings since they can be bonded on with epoxy. I was inspired by an article that Russell Brown from PT Watercraft wrote in Professional Boatbuilder.

Was unaware that company still exists! Googling up the name takes me to the WoodenCanoe.org website's page showing an address and phone number, nothing else.

For some formulations of epoxy, yes. The stuff I've been messing with the last couple of years, supplied by MAS up in the Twin Cities of MN, I believe will work with epoxy colorants they supply for the 'art casting' crowd they provide with a wider range of similar materials.

So far I've had no need to try adding colorants, I'm more inclined simply to paint my results.

Here's a pic of where I'm currently at with the hinge/latch project:

Next is removing everything that's not intended to remain part of the finished items.

The wood portions are simply spacers to enable more economical use of epoxy when doing the hand layup of each 'leaf' of the two-part sets for both hinge and latch components. There's a subtle difference in how the respective parts are shaped that puts fiberglass where it's best suited for the stresses each part will have to bear up under.

I need to fabricate a second set of four halves for my project. What's pictured is what will be mounted to one side of my ama, a hinge on top and a corresponding latch on the bottom.

Re: Pintle and gudgeon sources

This boat, a 20 ton airex ketch, has fiberglass rudder fittings. And there are 6 more like her.
The only metal is the pin
build female fittings ,pop the pin in later


you can sort of see how they are
eff bronze, it is just an ego trip at this point

Up to 3% universal or fiberglass specific colorants, less is more, beyond that you are plasticizing your goop. The colorized epoxy goes off a little quicker too. I just did the keel bolt overfills in my boat in RED.

Nice looking hinges Sp_Clark!
