Hi all,
I'm definitly not a designer like you guys. I'm a technician.
I love the fedora logo and I thought i can laser the logo on little stainless
steel plates.
WNr. 1.4301 (X5CrNi18-10), AISI 304 (V2A)
material thickness between 5 and 15 mm
extra fine polished, for a noble look
I tried to import an svg. the problem is that this wouldn't be conform to my
metal laser machine (and other major laser-machines which is used in this
industry sector). i can import it, but i will miss my 0-polyline and i can't
define one or import one from svg.
my laser will cut a square in the size i resized the logo.
another problem is that there is no seperation of "f" and "8" so the
middle
plates of 8 will fall out and i have 3 pieces (2 middleplates and the
mainplate).
So I had to design my own from scratch, because I have a these problems with
the original logo.
This is my first try and I draw it in less than 5 minutes.
fedora has (principally) a very easy logo

The center of the logo is the center of the "f-cross"
- outer circle
o radius 125mm
o radius on the round edge 25mm
- inner circles f/8
o inner radius 35mm
o outer radius 50mm
o flat cutting is 15mm *
o radius on round edges are 5mm/each (of course)
- the seperation (f/8)
o radius 7.5mm
0 distance between circle centers are 15mm *
* I selected 15mm for the minimum distance of all laser-cuts, because it would
be more exact. the distance between the cuts should't be less than the
material thickness. btw this would make the plate logo more stable. (it can
be fallen down or you can try to press the inner-plates out with your
fingers, you will fail... :)
My only problem is:
You can recognize: "this is the fedora-logo."
but it hasn't the same aspect ratio and the strong separation (to keep the
middle in it).
I'm sure I would tresspass against the guidelines, if I will laser this
on a stainless steel plate :-( , or not?

A thought - I don't know what model laser machine you have, but the ones
I've seen do both engraving and cutting. Could you engrave the
"infinity" part and cut out the "f-cross" part? That would keep the
aspect ratio intact.
Another technique I've seen done involves creating slits for shading -
the distance between the slits can be less than the thickness of the
material, since the slits are so narrow, especially if the material is
as strong as stainless steel is.

It's a metal and steel plate laser. not one for filigree pieces.

nope

Double nope, i sketched it from scratch, just with sense of proportion.

why slits for shading and how? there are halfcircles building the
bridge. so.. the halfcircle-brigdes at the oter end are always in the other way.
makeing the halfcirclebridges flat and the middle bridge is just an is ugly,
like the solution to bring together the halfcircles.
ugly = )) ((
ugly = )) || ((
nice )) ((
I will try to make a prototype in a free minute. Tommorrow or next week.

Ages ago i played myself with a simplified version
(http://fedora.nicubunu.ro/artwork/logo/bubble_mono.svg) intended for
very cheap printing but it was pointed (and i understood) it is breaking
the logo usage guidelines.
However, in your case I don't really see a better option than you tried
(but i also lack any experience with laser cutting). Hope Mo and Paul
can get you more useful answers, since they are more suted to talk about
logo usage.

I can't speak to the logo usage/legal part of things, but a couple
engineering buddies with more laser experience than I've got concur: if
you can etch the "infinity" part, all problems are solved. (I've yet to
find a laser cutter that can't engrave, and they seem to be making
similar assumptions.)
