is it just me, or is the national insignia way too big ?

Yo "Bolt"...Not sure this is a good time to be "nit-picking" the man's baby.

I gotta' agree with Wrench...I'd do a flush repair instead of a patch. Find yourself a GOOD aluminum welder. I used to work for a guy that could make damage like that practically invisible.

ps..You know me. I'm not afraid to "axe" questions. What's a "cart full of table"?

2000 series aluminum is not weldable

When (not if, WHEN) you find out who did this, I have a solution to improve the driver's attention span. It's called "negative reinforcement". Tools required:
- steel radio antenna from 1979 or earlier American vehicle
- slip joint pliers to remove same from vehicle
Walk the offending driver over to the punctured B-25, have him remove his pants, then whip him in the sack with the antenna several times while loudly exclaiming "DO NOT EVER TOUCH MY F*(&ING AIRCRAFT AGAIN!!!" Naturally, other forms of "wall to wall punishment" are highly encouraged as well. Using such reinforcement methods, the odds of him banging into your Mitchell in the future would be significantly reduced, I promise you. Well, that's what *I'D* want to do, anyways.
Sorry to see your bird get punctured, I hope you can get it straightened out...

That alloy is not weldable from an aircraft repair standpoint. You could make it look OK but it would not have equivalent strength to an undamaged part.

Jack,
I know your pain and your disbelief that this could happen. I had an incident some years back when I was pushing the Skyraider with 3 guides watching when I hit the wing tip nav light on the Strikemaster, I wasn't aware of a problem until I heard a very loud "POP" that was the lens breaking....thank god I was going very slowly......I am sure you will get to the bottom of it and make any needed "adjustments".

Ok, let's start a Jack Patch fund. I'm in..........
Some people, keep your ears open, somebody will let it slip...

That's why I don't throw the chocks anymore. A perfect up and over..... took out the strobe on a 414 one time....

[b]THE ALUMINUM ALLOY SERIES
Here's a list of aluminum alloys, their characteristics, and their typical
applications as listed by the Aluminum Association.
Series Characteristics Uses
1000 Series Using 99% or higher purity aluminum, the compositions in this series are usually strain hardened. They resist corrosion well, and have high thermal and electrical conductivity.
2000 Series Copper is the alloying element of choice here. Heat treating yields properties similar to mild steel. Sometimes they are artificially aged for even higher strength. Sometimes combined with 6000 or 7000 series alloys to increase corrosion resistance. 3000 Series Alloys in this series are coupled with manganese. They have good corrosion resistance and formability. NOT heat treatable.5000 Series Magnesium, one of the few metals lighter than aluminum, is used here. The resulting non-heat treatable alloys feature moderate to high strength. Extremely weldable, they are also very corrosion resistant.6000 Series Both magnesium and silicon enter the mix for this series, making them heat treatable and extremely versatile (especially the 6061 alloy). Formability, corrosion resistance, and high strength top the list of desirable characteristics. Body panels; bumper face bars; fasteners; body components (both extruded and sheet); driveshafts and driveshaft yokes; bumper reinforcements; brake housings; fuel delivery systems; luggage racks; and more
7000 Series Zinc is the main ingredient, although small amounts of magnesium and/or copper can be thrown in for special applications. All alloys in this series are heat treatable and have extremely high strength.

I'm very sorry to hear about this Jack!! Here's what she looked like four weeks ago on December 4th, 2006. It was about 9:30 AM and they were getting ready to back her outside to make room for a staff/volunteer Christmas party.

That sucks Jack. I keep thinking, the B-25 sits very high. In relation to the tow vehicle..............pushing backwards or forewards, how the hell do you miss a stack of tables that high to enflict dammage on the nacell???
Lynch party and Hang the bastard!
Another dead beat are parrents who allow there kids to walk on fabric covered airplanes!!!

This really sucks Jack! I hope you find the culprit and manage to fix the plane without too much hassles...
