MAX Update No. 24: New Front Fenders

2/19/2009 9:24:25 AM

Tags: MAX, 100 mpg, body,

MAX is getting its first 21st century body part fitted — a snug, low frontal area fender. Goodbye, classic charmer, hello, sports racer. When this project is done, we'll hardly recognize the old girl.

Don't worry, we're not throwing away any of the pretty stuff. We'll be able to swap back and forth between antique and zooty in a 10-hour day ... that is, once the zooty part is finished. Besides, the slicked-up version of this body may have some charm of its own.

So here you see the first new part out of the first new mold. In keeping with the keep-it-simple-keep-it-cheap philosophy, we're using one mold for both front fenders. We've put MAX up on blocks and removed the suspension spring from the right front wheel, so we can move the wheel up and down and see if/when/where it hits the fender. So far so good; once we have the fender positioned correctly we'll add the fender fairing (see Update No. 23 to understand what I'm talking about — it's the part that tapers back from the fender and blends into the rest of the body), then start building the “pontoon” that runs along the side of the car.

I think the front fender assembly will be the last MAX body part we build the old-fashioned way, where we measure drawings and saw templates and bend sheets and shape foam with big files and ... heck, even this part wasn't done totally the old-fashioned way — at least I had my Rhino CAD (computer aided design, if you're new here) drawings I could print full size and trace on the wood I was carving. Still, it took a loooong time.

Maybe not long if you're a redwood tree, but plenty long for a human being. I figure I can build a computer-operated foam carving machine quicker than I can sculpt a whole car by hand, and we'll soon see if I'm right. But right now, it's nice to see the streamlining starting to take shape in real, live, go-out-and-touch-it form.

hi Jack, Are you serious about building a 3-D router? If so, I have a whole bunch of stepper motors and leadscrews that would be useful in building a proto-type. If I remember right the leadscrews are about 12 inches long, and the stepper motors are about 2 inches in diameter, the standard 200 steps per revolution. Not near big enough for what you're doing, but I think you could drive them directly from the computer without using an SCR. I looked into it several years ago, and there were a couple of guys on the Internet that made router tables with a Dremel router. They were able to run it directly from the printer port, but I don't know how, or if they were able to get the third dimension. Anyway,if you need this stuff, I'd be glad to donate it to the clause. I'll send you the same message to your e-mail, I don't want to post mine here for fear of getting spammed. Best wishes, Tom
