I am getting pretty good at making inside curve flanges and ending up with a nice fit.
I do, however, plan to keep my day job.

Perhaps most exciting is that next week, I head to the East coast for the 4-day coach building class with Wray Schelin of Proshapers! (IMG:style_emoticons/default/smash.gif)

Very excited...

Hahaha this build is far from boring.
Your Mrs. and mine think alike.
I get told about my attitude in the garage sometimes as well.
One day I will understand this creation. I wish you would provide all of us tuning in
with blueprints and roadmaps. Heheh Carry on Chris!

Chris, Enjoy the class, I am sure you will pickup some new skills. I have a couple on them on my list, to do when I get a chance.

(My wife was gardening and poked her head into the shop at one point and said "No more "Goddamnits", please?")


(IMG:style_emoticons/default/av-943.gif) One evening my wife asked how the car project was going and I said it was going much better than I had expected. She said, "Really!? Then what's all the cussing?" I just grinned and said, "That's just part of the charm." I've instructed her that if the cursing stops, she should dial 911 because it surely means I've knocked myself unconscious.

Well, even yesterday's re-do #4 turns out to be another practice part. I want a taller flange so I can spot weld vs butt weld when I install the top piece. So... back to it. Again.

Here's a bit more detail of the how I made the piece.

Cut the blank, mark the bend line and use the bead roller to start tipping the flange.
The flange on this one is ~ 2x larger that the previous version so it took bit more effort to tip the flange. That's a fair bit of metal to move around.

Here's the first pass through the bead roller. You can see how tipping on an inside curve starts to curve the flat area of the material.

Pass # 2, more angle and more curving going on.

Third pass, almost there. Pretty curvy!I stopped here as I wanted to do some stretching to get it flatter ahead of the next bead rolling operation.

Note that the initial tipping was done with the thin top die and the large, flat lower.

A bit of stretching to get things to lay down a bit.

Stretch, check, stretch check, etc, etc...

Done!

What I didn't show was the final couple passes through the bead roller were using a wide, flat top die against the same flat lower to smooth the flange and crisp up the corner.

For the tool whores. A teeny little roll bender, just perfect for 1/8" rod.
Why would I want that? (IMG:style_emoticons/default/idea.gif)

Yes, it's April 1. No, this isn't an April Fool's joke. Tho I may end up thinking this was foolish.

I'm headed to the coach building class next week and I'm contemplating, just contemplating, mind you, giving a go to making an all steel wide body.

So as a complete waste of time, I started messing about, trying my hand at working up the beginnings of a wire frame...

The design would have to enable me to:

- run a radiator in each rear side scoop, ala the DP2 design pictured below.
(He's running an LS3 and having no cooling issues - and he has a muffler right behind each rad...)

- retain a fully functional front trunk. That'd actually be pretty neat and is a main driver for this silly idea

Yes, LOTS of things to think about and it may all be abandoned. But this build is, well, about the build.

Will it ever run? Who knows... Do I care? Not right now, too much fun in playing around and learning.

Trying not to let "perfect" get in the way of "0.1 is really, really close"...! (IMG:style_emoticons/default/lol-2.gif)
I can tweak it a bit but for now, I'll take it.

And with that top piece mocked in, I can start on the practice parts to work a design for how all the corners will come together. I'm determined to have that bead transition around all the flat panels but these corners are certainly going to be tricky.

I may have to enlist my bicycle building friend to help me learn how to braze and file so I can get the transitions to look good.

And with that top piece in, I could start "connecting the dots" and get a feel for what this thing will look like and how it'll work. Still not sure if the access panel will be one piece or a few.

And while it's not quite a blueprint, hopefully this will give a better idea of what I'm trying to do.
