Chapter 15 Firewall
I ordered the MKCS-71 and CS-72 Bracket pieces from CGProducts and the sheaves from ACS and assembled them. I also fitted MKCS-71 to the lower firewall, which required a minor amount of hole opening to match the pre-burried bolts in the firewall. After I had run the rudder conduit cable (referenced below in Ch16 Step 5, I could see that I needed to grind about 1/8" of opening in the electrical conduit corner on one side to align and flox the rudder wire conduit and line up well with the sheave.
I've stopped here until I get the turtleback and upper firewall finished in Ch 18. I'll also get a picture in to clarify the above then.
It turns out that I didn't mount the rudder turning blocks throughout all the chapter work until after mounting the engine. The reason for this is that these brackets and the pulley's are not needed until I get the wings mounted for good and connecting the rudders. I wanted to keep them safely stored until this point.
The next big work on the firewall associated with Ch 15 is when the fire shield is fitted along with the fiberfrax. I have this documented in Ch 23 Engine stuff because it's so closely linked with all the engine associated protrusions through the firewall.
