I would like to see what others have done for inspection panels at the tail, pictures would be great. At the front stab attach I am thinking make an aluminum ring similar size to the plastic inspection plate rings, and a slotted cover so it can be slid off. I want to be able to change the stab...

Finally finished my fuel system from the wing roots to the firewall. Took way too much time and I have a pile of discarded tubing. I found this one of the most challenging parts of the project so far. One of my goals was to use one piece of tubing from the wing root to the T, eliminating the...

I believe that several have located their transponder antenna between the gear legs. This makes sense in that it gives you a ground plane but I wonder about the gear legs blanking out the antenna signal. Seems that is a more important issue with ADSB now. Also my trans instructions say that the...

I'm running tubing in the fuselage for the static ports. I'm using 1/4" poly-flo tubing and 3/16" polyethylene fittings. The tubing id is smaller than 3/16", I have to warm the end of the tubing to install the fittings and they seem to seal tightly. Do I need to use some sort of clamps to secure...

Is there any FAA guidance with naming an engine modified to experimental? Looking through lycoming engine designations my engine is now closest to the IO-540D series, has the same rpm limit, compression ratio and spark advance. So I am thinking XIO-540D, or IO540D EXP. Does someone know where...

These are the brackets I welded to the ceiling structure for a rear overhead light and switch and headset/mike jacks for the rear seat passengers.

I'm in the process of running wires in the fuselage before installing the interior fabric. Was somewhat shocked at the cost of wiring. As an example to wire the rear seat headset jacks, need 4 runs of M27500 24 ga 3 conductor shielded wire, totalling 50 feet. Aircraft spruce gets $1.12 per foot...

Finally, took two weeks but now have the fuselage and tail feathers, engine mount, landing gear etc. all sand blasted, primed, and top coated. I was fighting unusual wet, humid weather, the borrowed sand blaster self destructed so had a few issues. I am using Stewart Systems paint which is new...

From the start I always planned on having separate rear seats. That way with three people on board you can save some weight and have more room for baggage. I started with the design of the bench seat and modified from there. The seat back angle is adjustable and the back folds down over the...

The fellow helping me build my engine says I don't need a primer system with a fuel injected engine. Just open the throttle and hit the electric pump to prime it. It has been so long since I have flown a fuel injected plane, I can't remember if it had a primer or not. Would be nice to have one...

Was able to attend this 3 day class in Lees Summit, MO outside of Kansas City. Timing was great as it was Weds to Fri the week before Oshkosh, so I flew to KC and then on to Oshkosh. It is hosted by the Aircraft Electronics Association which is the trade group for the Avionics industry. I read...

While sitting in the rear seat taking measurements for the harnesses I ordered, I realized I had virtually no headroom and I'm not that tall, I'm afraid the seats I built are too high off the floor. Could someone with the Avipro bench seat measure from the floor to the center of the T14 cross...

I had bought an O-540B4B5 core on EBAY several years ago. It was 2800 hr never opened up out of a Cherokee 235. Back in March one of our local EAA chapter members brought John, a retiree with 27 years experience building engines at Western Skyways in Montrose, CO. He has opened his own shop...

I guess Jared is too modest to mention his article in June AOPA pilot. Really good job of writing and photos. Something I have a big desire to do, but will have to wait until the Bearhawk is flying.

I gave some serious consideration to covering my plane with Oratex. For a variety of reasons including price I have decided against that. However, I think it would make an excellent interior fabric and save a lot of work. I'm planning on going with the 6000 silver. I had a concern about the...

Sometime this summer I will be sand blasting then painting my frame. I will be using Stewarts Ekopoxy topcoated with Ekopoly. The only spray equipment I currently have is a Croix HVLP setup. It actually worked well for spraying my Maule frame with Polyfiber products many years ago. I understand...

I'm going to be using a lightspeed electronic ignition, backed up by a slick magneto. I am thoroughly confused on which slick part number to buy. Looking at an O-540 user manual, it says the magnetos turn clockwise, looking at the accessory case. I called Lycoming, spoke to a tech and he...

Finally getting around to installing these pieces on the wing. I initially tried to force the flat pieces into a curve and clecoed them to the pocket ribs. The pieces were stiff enough that even with everything clecoed together tight against the pocket ribs,the skins were pushing the top wing...

I had decided I did not want to use a hose connection between wing and fuselage fuel lines, mainly because I didn't have a beading tool. I installed bulkhead fittings in the wing root and planned to run the fuselage lines to connect there. A consequence of that is that the fuel lines out of the...

I have never liked the fuel vents that consist of a 1/4 tube cut at a 45 deg angle facing forward. I have cut my scalp on these at least once. If you bend the tubing so it faces forward you risk having an insect plug it. Someone on the old yahoo group used to sell streamlined fairings using...
