Brief Description: RD: Trimmed R-710, Enlarged hinge hole on R-704
With all the issues listed on the web pertaining to inadequate edge distance after trimming R-710, I approached it with some caution. I marked and cut (1st with the aviation snips and finished on a belt sander) making sure to leave more than enough material behind. I then test fitted R710 to R704 (Rib) and R-405PD rudder horn, gradually taking more and more of R710 away until the was just right.
I also enlarged the rudder hinge hole on the forward flange of the R704 Rib with the unibit to 3/8 as directed. I then employed the services of my wife to hold everything in place whilst cleco'd it all together.
