Generous offer,

It is much appreciated.

I too can do the drawings,
The dimensions are what I need also.
Just don't have the parts "in hand"
to get them.
My cad software has a "trace function"
I inserted the 2240 cut away photo/cad
rendering that Gil produced, and has been
seen many times in the various forums.


It was of course not to scale, but since
I knew what size diameter the air tube was,
I was able to scale it after it was traced.
It is not a great tracing, (may have to play with
the settings in it) but it did give
me a good reference. I will be extending the
length of the upper of the three tubes, and
keep the lower two at 12 inches long, I intend
to cut a support for the rear of the lower tubes
that will be anchored using the front grip screw.



EDIT: Here is another drawing showing tube placement,
& end cap options.
