Rudder hinge - pint-less and gudgeon-less 

Ted Cary and David Beede

michlinerud.gif (5639 bytes)  I ran across his review of Ted Cary's idea about using nylon seat belt webbing in place of pintles and gudgeons. (The hardware that holds the rudder on.) Mounting and removing the rudder should be easier. Though it takes  a little time to make, the materials cost is negligible. 

Here's Jim's sketch. His write up on it is here.

kerf.jpg (5612 bytes)kerf2.jpg (6534 bytes)   I started with a 10" piece of 2x6. I cut a 7/8" deep saw kerf down the center. The yellow dotted lines show how I modified the design by tapering the insert. In instrument building this trick is used to join necks to bodies. When you insert it it will snug it up against the transom.
taperjig.jpg (6509 bytes)  This could all be done with a hand saw, but I used the table saw. I don't own a taper jig. But here's an easy way to cut a taper using a scrap of plywood. I set the saw to 25 degrees and clamped the fence about 5 inches away. I ran a scrap of plywood throught the saw.

partsrudderhinge.jpg (10068 bytes)  I shortened the receivers so the wedge is longer so I could tap it loose if it should get stuck. I've also rounded the edges and sanded them some. 
ruddersheet.jpg (47916 bytes) Here it is on the boat. It works really well. It's totally quiet and drops in securely. It requires a slight tap with an oar blade to remove it. After about a year the webbing is beginning to show signs of wear in about the top and bottom 3/8" - its getting soft, loose and shows signs of fraying. It wants to twist while in use and puts pressure in those two areas. Next I'll try hinges.
rudhingeclose.jpg (36305 bytes) rudhingeclose2.jpg (24979 bytes) Hi David, I tried your combo strap/gate hinge idea, pure genius is all I can say, the simplicity of the whole thing is just awe inspiring...not to mention cheap!  I just wanted to say thanks for the great idea... 

I'm going to do the exact same setup on my D4, because it worked too well on the mouseboat.  [Here are] a couple of photos for you...  At the risk of being rhetorical, I can't say thanks enough.

I noticed that Jamestown Distributors has SS and Brass hinges for as little as a buck or two a piece. With them I think this rudder solution could be as effective and long lived as the usual set of $30 or $40 pintels and gudgeons.

simprigrudderhinge.jpg (12932 bytes) Well I finally got around to trying a hinge on this alternative rudder mount.

.Here's my hinge arrangement for my Mini-Sharpie. I'm using a single butt hinge from a door.

Main Sheet Fair lead in tiller....not entirely on topic.... but....

ruddersheet.jpg (47916 bytes) The main sheet hole I put in the tiller works great. Jim Michalak recommends a fairlead on the tiller near the pivot point so you can control the sheet and tiller with one hand. While making a wooden fairlead I realized I could just put a hole in the tiller instead. It's positioned such that I can pinch the sheet between the tiller and the rudder head's stop ledge.  You can either hold the sheet against the tiller or pinch it by keeping the tiller pressed down. A lift of the tiller lets the sheet run free.
