Hello, new to forum, been lurking a while, messing with a newly acquired 30 year old H14 and learning to sail it.
I'm replacing worn out pieces of the rudder system and made some new rudder pins out of 6061-T6 3/8" aluminum bar stock. The question du jour is: What holds the pins down? Gravity? One of mine keeps rising, I see any number of ways to fix the problem but why do I have it in the first place? I had to shim the lower gudgeon with a plastic bushing and the pin fits well. Any insight would be appreciated.
Thanks,
Gene

The stock Hobie pins have holes drilled at the top and bottom for cotter pins. If you've fab'd some pins you can drill holes through the pins horizontally (if holding the pins upright) and find small cotter pins that you can push through and lock. I ususally keep my bottom pins removed for ease in removing the rudder assembly.

They can be purchased in either aluminum or a fiberglass version. I prefer the fiberglass version so they will shear should your cam lock fail during beaching - thus saving a rudder or a rudder casting.

The rudder pins have cotter pins top and bottom for a reason. For starters, if you flip the boat, especially if it turtles, you risk having you whole rudder system falling off. It happened to this guy. (viewtopic.php?f=14&t=32051)

I use what is sometime referred to as a hairpin cotter (http://www.pivotpins.com/catalog/hair_pin.shtml) for the bottom pin so it is easier to remove the rudders when I trailer it.

It is best to keep your rudder system properly maintained. If they don't kick up properly, I don't think plastic pins will save much. The extra force is largely perpendicular to the rudder pins and will likely damage your transom instead.

AH-HA! Top AND bottom. My cobbled-together rudder system had home-made pins that lacked the bottom hole. The cobbler had a reason for this but it's not relevent to this discussion. Also, I now see the (4) cotter pins in the Saltydog picture. Duh. Thanks for the insight folks, and the great hair pin idea.
By the way, the cost of materials, including the stainless cotter pins, to make the aluminum rudder pins was $3.43.

I also make my own aluminum rudder pins (cheap and easy) and use the "hairpin cotter" pins on the bottom. These are called "keeper" pins in the Hobie Catalog and "Spring Clip" by Murrays. Make sure you use the SS ones, and don't be tempted to use the cheaper "Safety" pins for this application. They're just too likely to come off accidently.

Sure, send me 100 yuan.
Seriously, MetalsDepot.com sold me (2) ft. of structural grade 3/8" aluminum round bar for $2.34. I bought some other stuff for stock to help negate the shipping. Stainless cotter pins are $.25 apiece at the hardware store - or - about $7 per 100 from MSC who also has the stainless hairpins for about $35 per 100.

Wow! $15... that's a deal.
I think I can handle making my own but your experience is encouraging, thanks!

We use stainless gudgen pins down under.

The alloy pins can corrode and bond with the rudder case and then be a real fight to get out.

I've replaced the pins on my 14T and 16 with the stainless ones sold by my local Hobie dealer.
