Paul, I have had some time to get back to my CAD education with Alibre.
  I'm working out the cowl profiles, and was wondering if you had some
  simplified models of
  the 13b in combination with the RD-1c and Doddridge plate. I was hoping to
  kinda stick
  them in to make sure everything clears. I'm using the extended mount
  dimensions for the
  lightweight version of the 13b on the Zenith CH-640.

  Try some of these.

  -----------------------------------

  Here is what the jpgs renderings look like from that igs file I just
  sent.

  I have a model of your engine and motor mount.
  Send me a sketch of what you want the cowl to look like
  and I will send some renderings and igs if you wish.

  -----------------------------------------------------
  Here is the Rhino model I have.

  Looks like the best place for the rad
  is underneath  with your extended MM.

  C. Smith,  I am attaching a rhino file of the Mazda 13B which I got from
  the
  newsletter. It is dimensionally accurate and I have used it on three
  fusaloge designs since I got it.  You can erase any or all of the motor
  mount tubes or rotate and extend them to your hard point locations.
 Besides
  being dimensionally accurate it does not add significantly to the drawing
  file size. I saved the dimensions of Jeff's motor mount plate when it was
  being reviewed on the newsletter but have not done a solid model of it.
 The
  attached file has a Schertz beam mount but can be swapped for Jeff's plate
  since the attached file is an assembly drawing of the individual parts and
  can be edited.

  Too big to publish George. Alibre probably won't load
  3dm files anyway. Export it as igs and zip it to reduce
  the size and send that.

 Paul, no problem saving to Iges in Rhino 4 but I don't know how to make a
 zip file. Is that some sotr of a right mouse click thing in windows
 vista.   If so how do I do
 it.
 GG

 In Windows XP you click on it with the right
 mouse button and choose send to compressed (zip file)

Paul,  I got the 3d of the engine converted, used the default style. It  is
one of 60 igs/iges formats available. I got to  the compress to zip and
e-mail page. It wanted a control panel mail icon configuration, that didn't
recognise the web address, the new contact menu wants 12 items, none of
which anyone would have. I got this file off the newsletter so could you
possibly post it again. It was posted about april this year. If not C. Smith
can send me an e-mail address to my yahoo mail at   george-grimes7@yahoo.com
and I can send the igs file to him as well as a JPEG of Jeff's Psru plate
with the dimensions to draw it.

So you did not find zip in your OS?
Are you using XP or something else. This MS changing their OS
is driving me crazy. They took so much stuff out just to make more money
selling it to you later.

I sent that one already in zip form.
Here it is again along with the jpgs of it.

Some people won't get it as some ISP's consider it a virus carrier.
