Started in on the 706 by locating all the parts, and fabricating the angles. The 729C angle had to be bent to 88.5 degrees, and I did that by putting it in the vise and squeezing a little. Worked great. Drilled pilot hole in that angle. Drilled and riveted the 729B angle to the 729A bellcrank rib, and drilled the 1/4 hole for the bellcrank pivot bolt. I chose not to prime these interior parts, per Dan Checkoway's web site advice. Drilled the 728B angle to the 728A Bellcrank channel.
