If you get it to work and you have a screen capture program that will
allow you to convert to a gif file<<

Here's what I get...looks like VCADD can't do it all, either.  Many of the
multi colored lines and text were too fine to show up in a screen capture,
so I converted them all to black, and size1.  There still appear to be lines
that VCADD didn't translate accurately, and not having seen the original,  I
can't tell what really belongs there.

For just uploading to the group, to have a look, it may be OK. Also, VCADD
converted the text to Arial, 0.25 inch, so many of the dimensions are too
large for the place they are supposed to go.  There were two dimensions that
extended several feet to the right of the drawing, so I deleted those before
I converted it so I could capture a view with as much of the main drawing as
possible.

It looks like drawings 2 and 3 are the same, but with a few more dimensions
and some hatching on 2.

Not sure if you can use these, so, take a look before they're uploaded to
the list.  I also saved them as .dwg files, so if you'd like to take a look
at them in all their color, I can zip them up to you, too.

Thanks Harley. They look useable.

>From the looks of it Ed you still had a bending moment on the
vac pump shaft. You need two bearings side by side and a flex
coupling to get all the bending and bearing shear loads out of 
the aircraft vac pump shaft when driving it with a belt. It is 
and would be a pain in the butt to do properly I know.
