Mon Mar 2 17:43:52 2009 - At times, I don't get this baffle kit. Some of the most complex parts almost fit like a glove out of the box. In this instance, this part contacts the ring gear. The other side fit perfectly. Go figure. Maybe it'll just work out as I progress. If not, it's trimming time. One thing is for sure, up until this point, things have been pretty easy. Looking ahead in the plans (i.e. the next page), the bottom cowl gets involved and there's some bold text explaining about an "iterative" process. Hmmmmmm

Sun Mar 1 19:10:18 2009 - Some interesting "tweaks" are going to be performed. Gonna have to trim this flange a bit for the MP line. Maybe I could use the MP port on cylinder #1 (far right in the photo). I chose to block off the cabin heat source from the rear of the baffles for two reasons 1) the heat muff is setup to accept a hose connection from the front of the engine and 2) should a leak develop, the cabin could be filled with nauseas fumes, 2a) it has been noted that the FI injectors may weep very small amounts of fuel and I'd rather minimizes those smells in the cabin.

Sun Mar 1 19:09:57 2009 - Started in on the baffles. All things considered, things are fitting pretty good. I did need to do some trimming of the aft right baffle near the center of the engine. I'm not sure were I'm going to put the Light Speed ignition coils since the top, aft, middle support bracket took their place. I'm also going to have to rework the left rear fuel injection line (again, because of the same bracket).

Sat Feb 28 10:58:21 2009 - Needless to say, I've given this a lot of thought and worry lately even though the solution was literally in the shop. The FT-60, aka the "red-cube", from Electronics International is a .6 to 70+ GPH fuel flow transducer. I chose this installation method for a number of reasons: 1) it is approved by EI on certified aircraft 2) this setup should be immune to errors when the boost pump is "ON", 3) keeps hose lengths to a minimum 4) Rob Hickman of AFS recommends and successfully uses this setup on his RV-10 setup. The short/lower hose is a Parker/Stratoflex 124F002-4CR-0034 and the longer/upper hose is a 124F001-4CR-0062. I ordered them from Precision Hose Technology. The transducer position/orientation is _very_ important. Otherwise, it may hit/rub/interfere with the prop governor line behind it. In this configuration, I've about 1/2" clearance behind the FT-60. Some notes: 1) The 124F002-4CR-0034 is the shortest possible length; 2) The "F" indicates firesleeved. If 124J (i.e. integral fire resistant silicon) is used, the minimum length is 4-1/2"; 3) 124J is not as flexible as 124F especially at the ends. Parker/Stratoflex 124 hose part numbers are available in the 106-124 catalog from Parker website.

Thu Feb 26 17:53:36 2009 - I called up MilSpec the other day to ask for some "-2" studs. They offered to replace all my studs and receptacles for a newer and slightly shorter design so I took them up on it. The new design is pictured on the right. The new threaded insert is _maybe_ 1/32" shorter and the cage is now chrome plated steel (just like the original spring lock). Drilling all the rivets out wasn't too bad. However, drilling out the CherryMax rivets was a new "adventure". Do yourself a favor, and get the process manual from Cherry Aerospace. To me, the trick was to make sure the center punch was performed accurately and then drilled with a #40. The rest is in the process manual.
