Dane said it well, about putting one's self in the other guy's shoes. And I am sort of picking up what Jaro is saying. Not everyone has the luxury of unlimited patience and the amount of labor required to learn to do this in one piece, from where you stand, regardless of your limitless dedication to learning the technicalities and fundamentals... patterns, bucks, fibers, and what not... seems absolutely ridiculous. Stupid, from where I stand. But some folks are willing. My motivation comes from a job, not a hobby. So I learn on the fly without weeks of internet research and study. The advice reflects that.
I didn't realize you had a wire buck under the thing. That might be holding you back. I thought you were planning a flat around the lip. During the week, there isn't time for me to absorb everything but I tried. I think you can see though, that I recognized my / our novice limitations and that those are valid.
Understanding now about the lip, my advice about multiple pieces would change. Fast forward to now, and what I see is what I am usually told when I ask about wheeling: Keep going. In other words, you don't have enough depth in the 11-15 area, out near the numbers yet. And if it was me, I'd clamp it in that vise about where 8 would be and I would twist the whole thing a little. Then I'd open the jaws up, lay it over those and hit the backside because more bend is needed toward the front than you'll get by wheeling til doomsday.
Thats one reason I said the wire buck may hold you back. Imagine the part already attached to the quarter and what you would do at the lip to change the contour, instead of the other way around. That might provide the "A-ha!" for you.
I would also suggest that doing this the dumb way, in pieces, may provide necessary insight for you to build on that could enable you to graduate to a single piece version. A welded piece is no less a piece than one not. The only difference is bragging rights and frankly I think that is the main objective here, with this. So if you want to make a flare, I can probably help. If you want to fit in among the self proclaimed elite, you're on your own. We have communicated plenty in recent years for us to get a feel of one anothers' personalities.
All that having been said, dude just get a photo resizer app. I did. Because my device situation is complex like yours. But yeah, thats all you need to make that simpler, man. I am not going to suggest one, I just picked a well-rated free one from the ocean of resizing apps available for my type of phone, that had the desired features. Ended up rarely using it because I had to get away from this site before egos got the best of me. I am here now because yes, to some degree I took you under my wing a little. I'm a Pontiac nut and bodywork specialist. Could I make a flare? The only way the world could find out is for me to get a customer request.
Again, good luck. Hip shooting with no formal training here. Give it hell, Schroeder. I'd like to see a mark in your win column.
And I just invested another hour of prime weekend trying to assist you. Make it count!
