So send me a ticket. ;)

rennch 06-11-2007 06:23 PM

Well...maybe we could talk website too, and I'll write the whole thing off when the time comes.

Where are you?

Zeke 06-11-2007 06:34 PM

Being a carpenter for 37 years has given me some unique intuition as to how things align. I'll bet some bodyshop guys would LTAO at some of the stuff I do when it comes to measuring and setting up. Let me offer another thought or 2. Use templates, paper, wood or otherwise. And a cloth seamstress tape is a very good tool for finding dimensions on compound curves.

We should take this off line.

rennch 06-11-2007 06:36 PM

Indeed...but it looks like I can't PM you. I might still have your email addy...

nononono - leave this on-line. This is rare tech for pelican.

eimkeith 06-12-2007 02:35 AM

oh yeah - large.

Chuck Moreland 06-12-2007 07:27 AM

Looking good. That's an interesting aero treatment you've got on the roof.

Chuck - that's proprietary - don't even think about it.

rennch 06-12-2007 10:33 AM

Keith...I wasn't suggesting that we take the whole discussion offlist...just the one where I was trying to bribe Milt into flying here and helping me with my project. :)

Hey Keith,

I have a buddy coming over today to help with the welding of the flares. Do you happen to have those numbers?

Thanks!

Glad to hear you got some local help. You can always brings pics and measurements back here to the forum. You get free help from multiple sources w/o any bribes. ;)

I'm actually thinking of videotaping it and putting it on the 2syllableword.com website as the first of my downloadable tutorials....

eimkeith 06-14-2007 10:34 AM

whoops, forgot about that - let me get you those measurements.

eimkeith 06-14-2007 12:37 PM

This is how we (Zuffenhaus) hang a 930 flare on a 911:

(make certain the flare is tight against the roll at the bottom of the 911 body - very important)

Disregard the outer edge of the flare you are installing - only the arch (of the wheel opening) is relevant to positioning.

First measurement (A) is from the edge of the taillight opening to the lower rear corner of the arch. Straight line dimension is 365mm.

Second measurement (C) is from the inner rear edge of the jack hole to the lower front corner (at line) or the arch. Straight line dimension is 470mm.

Now, the depth measurements!

First, depth from Fender A to Frame A (at the rounded boss of the lower bumper/valance support rod) is 325mm.

Straight line dimension of point B (top of arch) to inner frame directly behind it (over the top of the tire) is 365mm.

http://forums.pelicanparts.com/uploa...1181852682.jpg

And Fender C to Frame C at point indicated is 330mm.

Aside from that, I try to tweak the flare up until it is similar in height to the SC/Carrera flare behind it, for good clearance when the car is lowered.

I position the flare and use 3 or so self-tapping sheetmetal screws to secure it to the original fender. I use a ziz-wheel (abrasive cutting disc) to start a cut at the TOP of the 930 flare. Then I use a pneumatic body saw to cut about 6 inches in either direction and tack as I go, down each side of the flare. If you've fit the flare properly, it will not walk or wrinkle on you and will line up at the bottom edge when you arrive there. If not, minimal tweaking is possible. Upon completion of the cutting, the old fender section will fall out (unless you've tacked it, in which case it can be motivated to displace itself fairly easily.)

That should get you a well-hung 930 rear fender flare. I'm still working on the 930 to RSR thing...

(BTW, these images/measurements are from a factory 930, in case you were wondering.)

rennch 06-14-2007 12:46 PM

Wow. Thanks Keith. You are a rock star.

rennch 06-14-2007 01:54 PM

keith...quick question. Do you cut through both the flare and the body, or do you essentially trace around the outside of the flare with the body saw?

rennch 06-14-2007 02:03 PM

Can I assume these numbers work for an early car as well?

eimkeith 06-14-2007 05:01 PM

We cut at the edge of the flare (unless the shape is goofy - occaisionally that is the case), meaning we cut just inside the perimeter of the flare - cutting both pieces of metal simultaneously for an exact fit.

I'm assuming by early you mean SWB? - and if that's the case, I'm assuming that if you are flaring a SWB you are also converting it to LWB. So, yes.

Zeke 06-14-2007 05:15 PM

No, he has a '69.

Keith, I don't think anyone has nailed it as precisely as you. Great writeup!

eimkeith 06-14-2007 05:35 PM

ok, cool - all that should be the same for a '69. or earlier, if you are converting to LWB.

BTW, I slept at a Holiday Inn Express last night.
