guess it's something like a special certification, but i guess it's kinda expensive, both for the process and for the material.. I think it would be a redundant operation.. U dont keep an airplane airworthy by strenghtening it, but with recurrent inspections.

Hi Alex:
No you missed what I was saying. I was mainly saying that if you machine the part, then it's not being built to the original specs. Stress concentrations could arise from work hardening on the milled part.

ok, but u can always redo it according to the original specs I guess. I know a couple of european workshops who might make it.
I'm still not fully convinced of the "old-NOS" formula, had some seatbacks with it and i dont wanna stumble in it anymore.

Hi Alex:
Being such a stressed part, you might have to have it tested alot of times until failure, and you'd need some high Quality Control standard to ensure no defects. If you were sure of your tests, then I suppose you could build a prototype pair. You could test them on your Harvard, and inspect for cracks every as required.
However, don't try it unless you are qualified to do it, and you'd want to make sure it's legal in your country.

I'd have a certified workshop to do it for me if necessary, mate

Ok Alex:
Just be very careful. Too bad Mr. Bela isn't on the board today, he can tell you a lot better than me.

Guys,
Every time there is a thread that is somewhat informative, it gets cluttered up by the same BS by the same 2 or 3 people who seemingly don't know the first darn thing about what is actually happeneing in the warbird community. This webpage can be very informative however you have to read thru garbage posts by the same people who have multiple posts on just about every topic. Steve P. mentioned somewhere else that many real warbird people won't post on the computer forums, I feel this is because it is just just opening yourself up to criticism by computer geeks who will debate and argue with you just for the sake of it then start telling you that it is there right to debate on a public forum because of the first ammendment. Every (most) informative topic ends up going the same way.
BTW: How do you guys have so much free time to spend on the computer, it's no wonder your T-6 (or any other) restorations will never get done.

To answer a few questions on this thread:
The masking and stripping took a good day to do right so you dont mees up your paint job. The inspection and recoating with primer took another. It is a tedious process. Maybe you should consider replacing old wing bolts with new ones while your doing this.
We made an entirely new stress panel in one case and it took more than a week to do it by someone who is very compitent.
The crack was along the wing spar area.
I have never personally seen a T-6 flown without wing attach fairings.
Also, you should look for corrosion just behind the gear door position on the inner attch point. Seems to be a common place for it.

And if I might add, the fairings are a breeze to remove. It took us a big 30 seconds total time to get them off and then back on the aircraft.

Hmmmm... Ever drilled titanium before? Titanium is also quite a bit stiffer than aluminum and has a significantly different coefficient of thermal expansion. Oh, and titanium is shockingly more expensive and significantly more difficult to form as well.HarvardIV wrote:A titanium attach angle would be awesome! Possibly Titanium could be riveted directly to Aluminum w/o dissimilar metals corrosion.
This sounds like a monumental engineering challenge to me!

Hi Stumac:
Since 2-3 of us are so wrong, please inform us on really is happening.

Well BDk we'll need SRPatterson and Stumac to show us the right way to do it.

Hello Chuck,
Don't forget to mag inspect the nuts and bolts! Looks a lot better in the Log Book too.

What a friggin idiot...
Harvard IV is either:
1. Some teenage kid who's never flown anything other than a PC, and who has nothing better to do than spend hours on the computer trolling. Or...
2. Someone who's entire knowledge of warbird restoration comes from boxes marked either Revell or Monogram. Or...
3. Some friggin idiot who's just getting in the way of some very serious discussions.
I believe there should be nothing diplomatic about this forum. Ban the little b*stard. Not for a week or two, but kick his stupid *ss off here for good. Come on Scott, it's time to lead WIX to a higher level. This kind of cr*p will kill the forum if you can't control it.
Fix this, and let's get back to some serious work...

careful with the snotty comments guys. If, in my opinion, someone is goading someone into an argument I will take action. Operative term here being in my opinion.. you are all adults, act like it. Banning is next...
