Don't know how I can help with the profiling, I no longer have access to any cad software or CNC cutters as I resigned from work few months back. So I can't digitize cardboard templates either Confused


There are things you can do without using a computer, you know...

You would use the profile gauge to find the profile.
Then, you would transfer the profile to a piece of cardboard,
using ancient tools called a "pen" or "pencil".

See, these were primitive "writing" instruments,
Before people had keyboards, they used these hand-held sticks that left a track when moved along on paper or other substrate.
Not only could they 'trace', or move along something to mark the edge, but they could also form written letters, even whole words and numbers.
All without a computer!

You would be surprised,
There are all kinds of tools out there, that don't even require a computer at all to operate.
They are called 'hand' or 'power' tools, and people do all kinds of things with them.


eh? whats paper?

yeah I know what pen is, its a drawing tool you can have on a CNC plotter.


Laughing

yeah Im too rough with hand measurements always get it wrong slightly. with CAD and set of verniers, dial indicator etc, CNC cutter to test proto types, I can get it accurate 100%.

I can do it your way, but its will probably be out somewhat and I have no means of checking the figures without cutting out a gauge tool of sort based on the figures.

Another idea would be to purchase a fiberglass rear apron panel from glassaction.com and use that as a template for the metal work. Cheap, available and molded straight off an NOS part. . .

Just another idea. . .


Oddly enough, Brent got one of those Glass Action rear aprons, and IIRC, the mid seam is flat in profile.
Brent was moving away, and we both were looking at it, and kind of laughing at it, thinking it largely worthless.
If only I could have guessed!

Way to think outside the box, Nate.
This ain't your first rodeo, eh?

Wonder how close those fiberglass aprons really are?
How to know if they didn't copy a bent one?
Wink


Dang, should have left it behind.

I know I still saved it, but unfortunately it's buried deep within a warehouse somewhere.

FWIW, I think the profile on it was pretty good and I wouldn't doubt it was made from a NOS one.

I think Gerson would make a killing selling these if he ever took them on.

From this thread, not too long ago:
http://www.thesamba.com/vw/forum/viewtopic.php?t=580004&highlight=apron

Doesn't it kind of look like the Mid Seam is flat in profile?


Looks are one thing; running my finger along a car that has never been out of the family and so I know 100% that it has not been hit, is another.

Not doubting anything at this point.
Thanks for checking you apron, your help is very much appreciated.

Are you 100% certain the the rear apron never got pushed or bumped in handling?
Never got wiggled or pulled upon?
Didn't get straightened a bit when the paint was done?

The Glass-Action site says something about "most aprons are damaged by people without the proper tools removing the engine" or some such. (their site won't load for me right now)

I know that when i was in high school i mangled all kinds of stuff without even trying.

Feel like an archaeologist, or forensic anthropologist.
Forensic anthroapologist? Confused

Maybe i will have to go to the rally this weekend after all.
i will be the one driving an oval, who spends the whole time making cardboard templates of everybody's apron! Laughing

Here it is...
"Most T3 rear aprons are beat up from someone removing the engine without the right tools".

And all this time i thought it was from installation of a quiet-pack exhaust!
Laughing

Hard to tell from such a small picture,
but,
it looks to have a bit of concavity along the Mid Seam,
and,
maybe,
a bit of Lower Buckle too?

Crazy as it might sound,
I vaguely remember looking at that glass apron and thinking that it just looked wrong somehow in shape.
Maybe i have never seen a good one, or have seen good ones, but never knew they were good...?

Yup, the only action back there was a stoplight tap on the right side that made the bumper JUST barely contact the fender bulge under the taillight. The apron was not touched. This car was my dad's, and then mine, so I know it's 100% original back there-- no bending, no bondo, no aftermarket exhaust, etc.
