We had four build sessions since our last update. EAA SportAir Workshop instructors Dick and Bob Koehler were in town over the weekend to lend a hand. With their help, we made so much progress. Here are just a few of the things completed:
- Oil door in cowling
- Angle of attack probe mounted
- Primer line run and secured
- Installed and wired 12V outlet
- Ray Allen stick grips installed
- EGT sensors installed and secured
- CHT sensors installed and secured
- Spark plugs installed and torqued
- Fuel lines completed
- Fuel flow sensor installed and secured
- Oil temp sensor installed and secured
- Breather tube installed and secured
- Engine dataplate reinstalled
As the wiring guy, Tom had the unenviable task of working under the panel.
The joys of aircraft building….climbing into the tail section. Not even sure who this is!
Installing the dataplate on the engine. You have to be extremely careful or your can drill all the way through the case (which would totally ruin your day).
Lots of adel clamps installed with the goal of securing and cleaning up all the hoses and wires. Oil pressure sensor installed.
Jerry with the nutplates riveted on the AOA mount. These were the first driven rivets Jerry has ever done even.
Matt installed the seat belts and shoulder harnesses.
Here is a good shot showing our Ray Allen stick grips installed. We went with the G205.
Once Bob and I had the primer line run, Tim stepped in to secure it and some wiring. Tim making sure the stick and primer/wiring bundle don’t rub.
I used EZ Turn “fuel lube” to seal the NPT side of our fuel line fittings. (You don’t use it on the flared fitting side, just the pipe thread).
Always skip the first thread and be careful not to have any sealant on the end of the fitting as it could block the fuel flow.
Installing the fitting on the fuel pump.
Dick mounting the master relay and starter relay.
AOA probe mounted. Time to take it off and paint the mount.
A beehive of activity.
Tracy cutting the oil door.
Tom holding the dip stick to make sure the oil door will be big enough to make it easy to check the oil.
Jerry installed the static ports.
Static port installed.
Jim working on an access cover.
Lots of activity going on.
I spent some time making the hoses to run from the firewall to the carburetor. These stainless steel braided hoses are pretty easy to make and look great installed. Here I am cutting the hose.
Tightening up the fitting. Note the tape I use to make sure the hose end doesn’t slip.
After completing the hose, I ran some mineral spirits through the hose and blew it out with compressed air to make sure no debris was in the line.
With the hoses complete, we should be able to test the fuel system soon.
Tracy re-installing the prop with the spinner back plate in position.
Cummings Spinner installed. Looks much nicer with the spinner.
Tom testing the stick selector circuit.
Bob and I securing the carb heat cable.
Dick and Tom working on the panel. (No way Dick was climbing in there).
Everyone head down and working hard.
Dick heating up some shrink tubing to complete some wiring.
Tom and Tracy doing some wiring.
With the comm antenna installed, Tom called OSH ground for a radio check….loud and clear!
Until next time….
