If your plane was covered the fabric would dampen the vibration. The good news is because your plane isn't covered it was easy to spot on your preflight! :-) -------- Scott www.ill-EagleAviation.com do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=192367#192367 ________________________________ Message 2 _____________________________________ Time: 03:56:57 AM PST US From: "pj.ladd" Subject: Re: Kolb-List: Nauga Field Flyin, Star Hill, LA I sat at the airport for about 2-1/2 hours this morning. >> Weather is upsetting everything in the UK too. Fairford, one of the largest Airshows of the year is set for this weekend. The Queen was there to review the RAF yesterday (It is 90 years since the Royal Air Force was formed. The first flying arm in the world independent of the army. Up until then it had been the Royal Flying Corps and essentially an Army organisation) The Queen reviewed the troops and planes , including the Battle of Britain Flight of a Spit, and Hurri and a Lanc.and just as she drove off the heavens opened up. The squaddies were marching off and the splashes from the rain rebounding from the tarmac was bouncing almost knee height Today they have announced that todays airshow is cancelled. Presumably because the main public areas, which are of course grass, are waterlogged. An announcement about the cancelleation of tomorrows performance will be made tonight. The money this has cost is phenomenal. There are Flying Display teams here from all over Europe, fighter, bombers, refuelling planes, the Raptor, the Eurofighter. Plus all the ground equipment and men required to keep this lot in the air. Must be millions of pounds wasted. On a smaller scale we have a fly in at my strip this weekend. Weather now at mid day is pretty gusty, scattered heavy storms forecast. Supposed to be improving later but I think there will be very few camping overnight. That means the BBQ is down the pan. A few of us will go to a local pub and hope that tomorrow, which is supposed to show improvement is up to standard but we had over an inch of rain yesterday so everything will be pretty mucky. Fingers crossed.

If they are at a vibration node they will happen eventually. Here's my not so humble opinion: wire feed welds are stronger, mostly by virtue of the high nickel alloy but also more rigid in a narrow band than gas welding, making them more susceptible to an earlier crack. A gas weld leaves a softer condition around the weld and I try to reduce this a little by sponge-water quenching. Right after the first hard landing I may (or may not) notice the weld joint taking a little set. After that it has reached a happy state of strength that will endure many more similar impacts with no further distortion.

Now, since you gotta fly and I want to fly, let's fly and keep the thread as a suggestion to others to do a preflight, OK. [Rolling Eyes] planecrazzzy wrote: > If you can just take it off....
