Rudders taking shape

I've been making some progress on the rudders. After roughing up the stainless shafts with my hand grinder, I added some spiral wrapped layers of biaxial fiberglass tape, and vacuum bagged it on where the blade of the rudder will be.

Then next step is affix the stations onto the fiberglass sections. I drew centerlines on the stations and then using a level against the front and back stations, marked the centerline along the shaft with a pencil. I wanted the keyway already machined into the shaft to be in-line with the stations, so I could take care of any Ackermann geometry in the tillers. My centerline on the shaft and the the stations turned out to not be accurate enough to use alone, so I got them as close as I could in position and checked alignment by putting a straightedge along the tails of the stations - making sure they were all aligned with each other. I think I am pretty close to being in line with the keyway. Any slight variation can be dealt with in the tiller connection to the cross bar. There I plan to have (on the tiller arm) an offcenter bracket pivot point where the cross member joining the two tillers connect. A future picture of that will clear up any muddiness in my description.

I tabbed these stations on with pieces of biaxial after a small cove of thickened epoxy. I did this after the epoxy I used to fix the position of the stations was set up.
