Default Didn't find this funny at all.....

...and I am VERY glad that you uncovered this and are correcting it. Kudos to you Mark. Actually it sent shivers up my spine as I read it, having had a very expensive lesson in this very same phenomenon some years ago. The good part about it was that it occurred in the cast iron pipes running from my kitchen sink drain downstairs under my basement floor, and did not happen in an airplane. The previous owners of my home were devout do-it-your-selfers, and they must have poured every kind of chemical down that kitchen sink you could think of, including Crystal Drano, et. al.

When the sewer smell in the basement became so bad that we could not stand it any more, I called the plumbers. $10,000.00 later they dug up all the severely corroded cast iron pipe to reveal completely corroded bottoms, and in some cases there there BB holes where the crystals had settled and eaten directly through the pipe.

From that day on I hoped that nobody would every have to experience that sort of thing. It makes me shudder to think that you probably would not have had any type of warning or real indication that something was wrong with the push rods in the plane until the very moment of critical failure. Very glad you caught this.

Vans, please change your wording for "liquid primer" in the plans, in addition to the myriad of other changes to instructions that fellow builders have pointed out for years, but I digress.........

Yikes, nice recovery to an honest mistake.
It would be interesting to to cut the tubes open lengthwise and see just what happened internally. Just out of sheer curiosity.

Default Liquid what?

Don't think I've ever heard of 'Liquid Plumber' here in Australia.... though we have similar products under different brand names ('Drano' to name one), so luckily I did not get that confusion.....

Default Liquid plumber

Charlie,

Thanks for having the guts to share. We've all had those moments where we did something similar. I've had a couple of those "why did they do it that way" moments, and almost always it was because I was misreading the plans or just motoring along and the old noggin wasn't fully engaged. Good reminder to us all to go back and double check and get a second opinion if we're not sure.

Dale

Default Fatigue

Mark,

Thanks for sharing this wonderful story. I'm sure it took some guts to post this! As others have already stated, We've all made mistakes in the building of our aircraft however, Your comical and innocent miss reading of the plans has put a smile on the faces of many people Around the world this morning. I'm THANKFUL you caught your mistake now and we're reading about it on Vans Air Force rather than an NTSB report. Your story illustrates one extremely important point, one should never ever under estimate the effects of fatigue! Perhaps you should pass your story on to the folks at Vans aircraft, surely they would get a chuckle too and they might use it to illustrate the importance of only tackling our projects with a fresh and well rested mind. In the builders manual where it states liquid primer they should add (NOT liquid plumber!.... Yes it's been done).

I know that more than once I read something in the plans and the brain processed something else and something had to be re-done $$. Don't be too hard on yourself Mark and thanks for sharing. Lots of people will not admit to making a mistake.

Default Two now- infamous call signs ...

[quote=SteinAir;760920]So I was all geared up to laugh about your story, then someone kindly reminded me that I'm the idiot who stuck my hand into a running propeller; so bad things can happen to good people...ESPECIALLY when you're fatigued or tired (I could "point" this out from experience, but my pointer finger makes less of a point now)!

Mark and Stein are special guys to display their mistakes right here in front of God and everyone. I have great respect for them both. And never have I seen two guys get call signs so quickly - or perfectly. "Rooter" and "Pointer" (I also heard Stein was elected captain of his bowling team after his incident. Any truth to that?)

I'm close to that part of the build. I will be reading very carefully. Thanks for the heads up!

It's all in how you read instructions..........
