Since I can’t do any more on the rudder skin until the part comes in I spent the rest of the afternoon starting work on the rudder understructure. To start I clecoed the double place onto the spar, then the directions had me work on the R-710 brace. I also fabricated a spacer the was .5” x 3.5” and tow strips that will go along the bottom the rudder lower rib, these strips will give something to screw the fiberglass end that goes on the bottom of the rudder.
I am supposed to cut out an area from the R-710 brace, but I am a little confused about just how much. The DWG shows an area to remove but no measurements. The part has some tooling holes located on the sides. If it is like the stiffeners then I would cut through the middle of the holes, but then this would leave a half hole which might cause a stressor and crack. There are no holes or half holes on the DWG. My thinking is to cut flush with the bottom of the holes. I have asked for help from other builders on this issue, hopefully I will have one tomorrow. So until then I am done for the day.
Photo 1 is the DWG that shows the shaded area to remove. Photo 2 is the part after a rough cut and a line drawn where I think the final cut needs to be made.
Note shaded area, no holes
Line is where I think the cut will end up
This show how the part fits with the spar and lower rib
