The original post is below. My buddy has the pedestal and associated parts for stripping and painting with AwlGrip. Aircraft stripper does indeed remove powder coat. https://drive.google.com/open?id=1OgW3dWk9fqRkoQwowu_fwg5fGehKcd_g
A local rigging shop is duplicating the wire rope cable for me. The fitting on the end of the cable that attaches to the chain is apparently called a chain eye as opposed to a marine eye or aircraft eye. There seems to be a major change in the rudder stop design. Touche' is Hull 83. Thanks to Russ, I have a good example of what a rudder stop should look like. Note the strong vertical structural member with gussets. The two plates mounted to the bottom of the quadrant stop against aluminum plates with rubber cushions on either side of the vertical structural member. https://drive.google.com/open?id=1_9BPN1H7YXs586x93QLT8saZVIKJxDSr Unfortunately, Touche' only has a thin gusset for the rudder tube: https://drive.google.com/open?id=1jaJX92DAx9vOgV2TWk-fchKrc3k3Zj2h One other difference is that Touche's quadrant is installed upside down from the one on Russ' boat. Go figure. That doesn't seem to be a big deal. The plates will just have to be mounted on the top of the quadrant. I am going to have to install a vertical structural member. Still finalizing the design but it will be similar to Russ' boat. Going to be very uncomfortable working in there. I'm thinking about bonding 3 pieces of marine ply together with the middle piece shorter so the thing slips down over the existing rudder post gusset. I can then through bolt it in place and then tab it to the hull. I will probably also make it with the athwartships gussets in place so all I need do is tab them to the hull. The gussets are extremely important due to the side loading of the stops. The more I do outside the space the easier it will be. I won't start the job until March after I return from skiing. I'll document the process and provide a link. Dennis C.
