If at all possible...throw the plastic in the garbage, install the hinge and latch on a 0.15" sheet of 2024, pass by comparison to original equipment, done.
Does it really matter if it adds half a pound?
One thing I could contribute that hasn't been mentioned is that the general policy at DeHavilland Canada, according to their sheet metal design manual, was such that features for which alignment was critical were simply not shown on the scale "undimensioned" drawing, and were shown on the NHA...

Why do you want to seal the cracks? The basic problem is that concrete in tension always cracks, and there's nothing you can do about it. Fibres make the cracks smaller, possibly to the point that they are invisible to the naked eye.

google says that if you want to glue glass to metal, you use this:

They say it's some sort of acrylate which is cured by UV. Acrylics I think are pretty stiff (high E)...among the highest modulus non-thermoset polymers anyway. I...
Hi JZuk,
Respectfully, I'm not sure I agree with you...
Et is a function of stress, and in the vicinity of the compressive yield stress, the tangent modulus is equal to the elastic modulus (by definition).
Ie at Fcy, Et=~E = 10.5x10^6 psi
Solving for (Sigma)cr using C5.1, k=4, v=0.3, and t/b...
Do I trust a mechanic to do a repair? Well...I trust a mechanic to bolt two parts together. I have a really hard time trusting him to glue two parts together.
The problem is that A) bonded joints are more sensitive and they are MUCH MORE DIFFICULT to inspect for flaws or imperfect bond than...
MNLiason some of those presentations are pretty cool, thanks for the link. The UAL one is great, and I would have really liked to have seen the Boeing presentation. It's very interesting that there hasn't been any damage reported yet to any 777 CFRP floor beams.
SWComposites: getting these...
Ok I'm just curious and throwing this out there to express my curiosity...
That 787 is going to be flying pretty soon, and they've spent the last five years hyping up how easy to inspect it will be, ie that if you can't detect any damage by tap-test, it's ok. That got me thinking...
That CAN'T...

"If you want to change an individual view from A to B, but leave some other views at A ... I believe you are out of luck."
That's not true, there is a way to (sortof) do it:
Make a copy of the drawing file. Do what zirtapoz suggests with that second drawing...
I'm not really fixated, I was just curious about a particular subject that I didn't understand, hope thats ok! :)
rb1957, you got me on the right track, making me sit down and think, well, what IS the deflection of the beam? Especially mentioning that your test structure never reached a...
Ok, just for nomenclature: a square tube as a beam has a compression face, a tension face, and two 'webs'. I'm talking about a 2.5 square tube with 3/16 wall. But more generally, it could ANY section, even a solid one.
I'm saying that, ok, I have to prove the section is stable in order to claim...
Hey everybody...
So, I have a square-section tubular beam in pure bending.
Plastic bending theory tells me that my applied moment is below the allowable. However, plastic bending is for stable sections...So I need to show that the tube doesn't cripple, or even if it does, it can still withstand...
You guys are way off!
If you don't heat treat after welding, you don't have a 6061-T6 frame, you have a 6061-??? frame. It is NOT going to be as strong as -T6, regardless of what filler you use. It'll probably lose 50% of it's strength, or more.
For certification of aircraft racks we use 8 ksi...
