What program are you using Robert so I can send you the aprropiate
file format. Also what excatly is this for? Who or what is KBR?

Hi Paul,

I too am looking for your 3D model of the 13B, 20B too if you have
one.
We're getting ready to start modeling the FWF and it would be a
great
help to start on your foundation.  We're using Vector Works and I
think
that a DXF file would work fine.

Also, did you ever get that adapter casting for the remote water
pump
made?  Can you send the DXF over for that too and we'll see about
making
some if not.

Thanks again for all your help,

Chris Cosman

In my experience DXf does not work for 3D. What 3D program are you
using?
I am confused about the term "adapter casting for the remote water
pump"

I have the casting pattern for the remote water pump housing.  I
made some
and sold all of the ones I made except a couple I kept for myself.

Are you referring to the part that bolts to the top of  block with
in and out
hose barbs? I never came up with a good drawing of that. A lot
depends
on which way you want to run the hoses.

Right you are, IGES is the format we need.  We're using Vector Works
for
the Mac.

The part the bolts to the top of the block was what I was looking for.

Matt just purchased a 3 axis CNC machine complete with plasma cutter
and
other fun attatchments, so we're eager to start making airplane parts
with it.

BTW Chris. It is easier to make that adapter you speak of out of 1/2
inch
plate and weld on tubing bends. A casting for that is real tough.
Probably
a couple of core boxes would be required.

Paul,  I too would like to have the drawings.  I have been using Vector
Works for a couple of years but have never advanced beyond the 2 D
stuff.   Maybe Chris can show me the way.  Jerry

That would be like the blind leading the lame! I just started working
with it.  But I am committed to figuring it out.  Hopefully I'll be able
to model as good as Paul someday.:)

Chris

Shucks!  Rhino makes it easy.
