Thanks Marcus - That one was done just to push the envelope with some new Hammer dies. (You would appreciate that I started with a 16X16 square of .063" 3003, and smooshed it out to 24" per side at .020" .... one annealing. And I always noodle out the dim changes = 60% reduction/thickness, 50% increase/edge length. Sorta at the upper limits, though I could push reduction more, it would only leave enough material to hold up the shine. ) I seem to get stuck with reverse shape stuff ... (mebbe should do a thread??) This one for a Beech Staggerwing ... P1010186 c.jpg P1010202 copy.jpg (airplanes can have some interesting reverse shapes.)

I wouldn't have thought it possible to create so much reverse curve. Mighty impressive. My attempts seem pretty feeble by comparison, I need to set the bar higher. Thanks for showing what is possible, with enough skill and experience.

The greatest impression I've gained from observing Kent "in action" is the tremendous focus and concentration he applies to the task at hand.
Your learning curve and the overall benefit you obtain from experience is greatly enhanced by focus and "situational awareness" YMMV

"Thank you!" to all you guys, Charlie, David, Marc, Peter, and Steve.
My first reverse was, I think I was a 3rd year apprentice, when I had to make a tail section of a Bugatti Atalante front fender - a very radical reverse that really twisted my noodle. What area to hit to make go in which opposite direction?? 1937 Bugatti Atalante HAC.jpg

Love the staggerwing. looks like the wingroot where it flows into the fairing for the retracted wheel. That is one helluva big panel to get to lie down everywhere! Did that start life as one piece Somebody here knows their business.
Guess you know Jim Younkin. He has bashed a few pieces of aluminum on staggerwings and others. Another hero of mine.

Beech Staggerwing, Jim Younkin, thumbnail dies
Quote:
Yes, I got it to lay down nicely all over. One piece, like orig. Got lucky early on when I started in the right areas. I got Jim to try our thumbnail shrink dies in 1995 - he was hand-rolling his Pullmax to make dimples. His Yoder was not set for shrinking, but it was set very well for his stretching. He is skeptical by nature so I just handed him the set of dies, told him how to set them and work them, and waited to see him at the next air event. He came galloping across the field when he saw me, exclaiming "these things are amazing, awesome, incredible!!!" (6 years after that he used them to make the polished 6061 round cowl for the H1.) I taught a 3day workshop at his place in 1998 and we had a great time together. When he asked me about making something in one piece or in multiples with welding and I responded with multiples and welding, he threw up his arms and exclaimed "Well, for you welding is a non-event!!!" Funny guy with a lot of smarts, loads of experience, and a ton of courage. Prof of EE at U of AR for decades. Patents on auto pilots kept his coin flowing.
