 Posted: Thu Dec 06, 2012 7:46 pm Post subject: Nose cone access |
 |
|
Kolbers, tired of standing on your head to access the back of your instrument panel, especially if you have a battery mounted in the cone? This is my solution: Make five fiberglass layups on the inside of the cone where the cutout will be. Draw the desired cutout on outside of cone and use a small Drammel tool to carefully cut the desired opening. Use clear packing tape as a release agent on the inside of the cutout. Tape the cutout back in the hole on the outside. Make five more fiberglass layups on the inside. Remove the cutout and trim the five layers of glass for a flange where all metal floating anchor nuts ( Aircraft Spruce part # MS21059L06) will be riveted to accept and secure the cutout to the cone with #6-32 counter sunk screws. See pictures for reference.
Have a good day,
Andy

I'm not all the familiar with the nose of Kolbs as I don't have one yet, but wouldn't it be better to put the instrument panel on a hinge? Other than that I like the idea,

Brad, As you said, you don't have one yet. There's more to this than just getting at the instruments. There are pedal hinges to be oiled, pitot and static lines to inspect. If you have hydraulic brakes you'll be wanting to service the master cylinders and cables stretch on mechanical brakes. It is VERY handy to have access to the forward end of the nose cone without going in through the cockpit and a whole lot easier on your back. I used the same basic idea as Andy's on my Mk IIIC except I made the flange from aluminum and riveted it on.
As I recall, John Hauck put his access hole on the bottom of the nose cone for the same reason.
On Ken Holle's Mk IIIX I took out the rivets and used screws to attach the entire nose cone so the whole thing comes off. I could get at everything while sitting on a roll around shop stool. Again, very handy for those maintenance items that have to be attended to during every annual conditional inspection.
