So far that dream has never been realized and it's looking like this year could be no different. I was very close two years ago when I trailered my yellow MK II up there, but my ignition got wet in a rain storm and it just didn't happen. Anyway, I got to thinking that even though my current aircraft project isn't going to make it, perhaps someone else would have a plane there that I could get a ride with. If you or anyone you know is planning to have a two seat sport aircraft at Oshkosh this year, I'd be willing to pay for a ride around the patch a couple times. You would seriously be making my year. Email me direct off group at radiobluebook@gmail.com if you can point me in the right direction. Sincerely, Duane ________________________________ Message 2 _____________________________________ Time: 09:00:54 PM PST US Subject: Kolb-List: video? From: Larry Cottrell I know that I said that I was most likely done making video's, but last night while in the depths of boredom, and finding nothing to read on the list, I began looking at tutorials on the Cyberlink program. Most of them concern making little rocket ships with a sparkle trail to go across your screen, but there was one that mentioned "video enhancement". It will also "stabilize" the video as well. I have always been disappointed in the quality of the video's here in the desert. Most of the time that they are taken is in pretty inadequate light, therefore it is pretty flat. You guy's in the watered part of the world do not have that problem. I had a few things that I wanted to see yesterday morning, and I took off early, just at sunrise. I took my Drift camera along out of habit more than anything. In looking at the footage, it was pretty flat and hazy, so I set it aside. After "watching the directions" on the editing program, I decided that the footage was the perfect sample to try the "enhancements" on. I made a short video, and saved it as it came from the camera, then made another with the enhanced version. The difference is fairly striking. The sky is still washed out, but the terrain looks better than any I have done. Now I know this won't tell you how to build any part of your Kolb's, but it will show you what it is like to fly one. It seems to me that no one is doing much of anything any way. Compare this one with some of the other ones that I have done, and I think you will see that the pictures are a lot brighter and clearer. Perhaps I didn't waste my money on this program after all. https://vimeo.com/100369914 -owyheeflyer Larry -- *If you forward this email, or any part of it, please remove my email address before sending.* ________________________________ Message 3 _____________________________________ Time: 10:02:14 PM PST US Subject: Kolb-List: Uncaged bearing - the dreaded "tink-tink" sound From: "wakataka" I thought I would pass along a little tip that might save someone some grief. I've got a 377 on my 1985 Firestar with an unknown number of hours. One thing I always do on preflight is slowly turn the engine over and listen for any unusual sounds. On my last preflight, I heard a slight "tink tink" sound that was not associated with any one spot on the rotation of the engine, and irregular in tempo. It's not very loud and you might easily think nothing of it. Fortunately, I had heard this sound before on a snowmobile engine. It's the sound of the balls in one of the main bearings falling down the back side of the race after the plastic bearing cage has gone away. When the cage is gone, all the balls drop to the bottom of the bearing. Then when the crank is turned slowly, they climb up to the top of the bearing and then fall one by one back down again. Each time a ball comes over the top and falls, it makes a little tink sound when it lands on it's neighbors hanging out down in the bottom. The engine will still run, but a catastrophic and expensive failure is in your near future if you continue to run with an uncaged bearing. I'm not sure what causes this. In the engine in question it was the bearing on the mag end. On the snowmobile, it was the PTO bearing and one of the center bearings. The crank was slightly bent on the airplane engine. I'm thinking that could have been a symptom of running with a damaged bearing or it could be the cause of the bearing's demise. The bearings in the gearbox have steel cages. I've always wondered why they use bearings with plastic cages inside the engine. So pay attention to those little things during preflight and avoid the big things later on. -------- There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.
