Hoi!
I thought I’d share some information on DIY rudder hardware. We have decided to build our own hardware, since the width of our rudder sets a higher price range for market pintles and gudgeons. We are going to use 4 mm thick AISI316L stainless steel. Here is a list of material properties:

So, our dealer said that this stainless/acid resistant steel is less prone to rusting after welding than other steels they deliver. We take their word, since some welding has to be done on the rudder pintle.
www.weldingtipsandtricks.com, in my opinion, is the best source of information for ALL welding applications. Here is an overview video on various stainless steels properties and some welding knowhow. Turns out that welding stainless so that it remains stainless takes practice. Oh, yes, before I forget, here is the video: Metals and Properties of Stainless Steels. And if you want general welding information, oh say when welding a steel sailboat, then refer to www.svseeker.com. Doug Jackson, building a 70 ft. steel origami sailboat, has uploaded a ton of good newbie-friendly information on welding on the page. Well, cheers, on friday we go metal shopping.
Our inspiration for rudder hardware comes from the Duckwors magazine:
Extra heavy duty stainless rudder gudgeon, RL-690-X.
