I just made a rudder out of wood for a dinghy. The rudder is designed to go into a box like affair so it can kick up.
I'm thinking that a super large washer of HDP maybe 1/16" think and 3' diameter would make it work smoothly and give it a lot of support.

Any idea where to find hdp or nylon sheet material to make it from?

David—

A thin piece of starboard would probably work quite well. I wouldn't use Nylon, as it doesn't like being immersed in water for long periods of time.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Look up a plastic tank manufacturer, the kind whom do custom water tanks for boats and such. They will have tons of cutoffs, and probably only charge a couple of bucks, if that. I made a similar setup once, but I found an old sheet of Teflon about 1/16". It was from one of those sliding exercise mats you could ski on from side to side. I found one at a second hand store.

HD cutting board

consider using a chunk cut from a HD cutting board available just about anywhere for a few bucks. Simple to saw to what ever specs you need.

David,

Go to a kitchen supply, hardware or even your grocery store and get one of these very thin cutting mats. Trader Joe's here in Fairfield had them for a while. They are come in sets of three... less than five dollars. I am headed over to TJ in a bit and will see if they are there and get the exact name for you.

These are not the self healing cutting mats used by picture framers and model builders.

I use them on the boat and keep a couple in my travel bag. You can cut them with shears or a utility knife. You application does not require thickness but larger surface area. They are great for many uses.


In googling them I found the following link which is fun! Audio Cookbook » Blog Archive » Wobbling a Plastic Cutting Mat

I have used these mats cut into strips as glides for companion way hatches as well when they are fiberglass on fiberglass.... I am not sure what the plastic is but nothing sticks to them.

John

I've been buying HDPE and SeaBoard from Tap Plastics.

you can get all kinds of plastic from McMaster-Carr. Look at UHMW. It lasts forever and almost nothing sticks to it. I used to make rudder washers out of this stuff for my Hobie.
