Now before I get flooded with e-mail, I did a test for radio interference. Now I know that this is not a very accurate way to test it but I sprayed two coats of paint on a cardborad box, and transmitted to an aircraft in flight from underneath it, I belive this would simulate any interference form the paint. I am also using a canopy mounted ant. I have finished wet sanding the entire airframe and finding areas to spot puddy, I will apply a sealer coat before the paint. My plan is to camp with my plane at airventure this year, is anyone else going to do this?

Subject: RE: KR> KR paint job To: "KRnet" Message-ID: Content-Type: text/plain; charset="iso-8859-1" Tim, My plan is to put the Poly Fiber Smooth Prime and paint on with a fine nap roller. A Pulsar builder in my chapter used this method with beautiful results. Bought the roller and pan at Lowes (about $6). Poly Fiber says there is no RF attenuation through any of their paint products over fabric or fiber glass. Carbon fiber will drastically attenuate RF signals. I will be camping in the camp ground in my pop-up. Look for me in the Workshop area showing folks how to use epoxy and fiber glass.

Good luck with your painting. As for camping with your plane at Oshkosh... you can bet that LOT's of guys do it. I even heard yesterday that a new campground has been created (with showers) for area 51. This is the area to to NW of the main show area and south of the warbirds. This area is primarily used for RV's and some canard types. If you want some shade and to be a little closer to showers etc, you may want to camp down to the south end where there is a small woods. Our job as "Welcome Wagon" drivers is to pick you up at your aircraft and get you registered and then take you where you need to go. For service, just watch for the cut down vans or tell the guys on the carts that park you that you request transportation. They'll call us on their radios. See you all at Airventure 2004.

I just finished hooking up the throttle cable, making all the plug wires, bolted on the prop, and thought I'd give it a shot and see what happened. As a former mechanic (maybe once a mechanic, always a mechanic) I'd already statically timed it so the timing was probably perfect already. [I've never understood why some people goof around with a misfiring engine while trying to "guess" where the timing is, especially with a prop a few inches away.] It fired right up on about the third blade (I'm not making this up) and ran smoothly at idle for the few seconds 'til I shut it off. It blew the contents of my shop all over the place, and the dust cloud is still drifting around! I guess next I'm going to fill the brakes with fluid and tomorrow it'll be outside tied to a big oak tree, trying to get a feel for what I need to do to my carb to get it jetted correctly, and maybe some real testing! WooooooHoooooo....

The same with checking the gap. I always checked the gap to make sure that it was set right for my application, because the "preset" gaps was often times wrong for my application, or if some one mis handled the plug, the gap would be closed up some and too small. Just be sure that any Anti-seize material applied does not get on the electrodes or it will foul the plug, and preventing one problem, will cause another. Oh, and just as a side note for diagnosing problems: If it was running fairly well before you worked on it, re-check everything you did last first before jumping to conclusions and beginning to replace parts to correct a self induced problem. I had many a junior tech make a minor error while working on a car, and cause his own problem, but the tendency is to rule out what we just did and look elsewhere.

Gigged items for correction, some minor some alittle more involved: 1) He did not like where previous builder had elongated the mounting holes to allow aligning of the 2 brackets. He said he wants to see just the correct diameter hole in 4130 steel for the brackets. 2) He wants the elevator bracket that attaches the pushtube to be welded to the torque tube, not bolted as I have now. 3) He wants the interference of the bottom 2 mounting bolts of the stick bracket with full aft stick on aileron movement eliminated. 4) Some placards were missing/fallen off; oil pressure/temp gauges need limit markings on them; choke needs id label; compass correction card needs to be installed. 5) One cotter pin was missing/omitted from one of the bolts for the aileron cables, needs installing. 6) Fuel tank needs label for type and quantity of fuel. 7) CDI ignition needs longer stud, stud stops before exiting the nut (about halfway inside it). 8) Battery box needs lid since I have a "wet" battery. 9) The oil pressure copper line needs a 360 degree loop added just before attaching to engine as cushion relief. 10) All engine wiring needs to be secured through out its run, and not to any that can rub it into shorting out. He recommended using terminal strips, and run bundles along the firewall. Where it was necessary to secure to the motor mounts or similar structure, use 2 tie wraps, one around the metal and through the 2nd tie wrap, and the 2nd tie wrap around the wiring to "stand " the wiring off from the metal so it cannot rub through it. Rubber insulating grommets applied to anything that passes through metal. Not bad for first outing, most is minor and easily taken care of. This Inspector was from the FSDO and was very nice, accompanied by a junior Inspector who was very nice as well. They were also very helpful and instructional on how to bring the plane up to "standard". Overall a pleasant experience, and encouraging information that with the corrections made, N96TA will get her Airworthiness Certificate and we can begin the test flying.

The other half had to be tapped lightly with a soft hammer to get them in. With the final installation, I spread varnish on the bolts and the fit was slightly easier since that acted as a lubricant.
