Paul, here is the prototype of your sheet metal Shertz Beam.
This
one
is mild steel, is only 15.5? between Barry Centers. I did it
to
see
what problems would present themselves. The stock oil pan was
used as
a fixture for positioning the side clips. The little lip on
the
pan
flange was ground off where it interfered. I reversed the
flange
on
the side clips in order to follow the curve of the pan. By
doing
so,
one bolt hole was picked up.The two outside end bolt holes
cannot
be
used unless the hat section is notched or a custom pan is
built.
Since the hat section exerts clamping pressure over this
corner
of
the pan flange, I don?t think the bolts are needed. I will
move
the
Barry centers closer to the end of the beam (1.25?) than I
have
them
in the prototype (2.5 inches). No real problems were
encountered
during construction.
Advantages:
1. No complecated machining.
2. Economical.
3. Retains stock oil pan if so desired.
4. Light weight. Bathroom scale says 5 lbs including Barrys.
The MMP fixture was easily modified to the Schertz beam.
Awaiting critical comments, but I think this thing is a
winner.

PS: I have a need for a 13B oil pan, a 20 B oil pan, and a
JUNK
13B
rotor housing. If anyone can help out with these items, it
would
be
most appreciated. I have checked the local wrecking yards
looking
for
a complete 13B junk engine to be used for fixturing. So far no
luck.
If anyone has a boat anchor 13B out here in the mid-west that
they
don't have a use for let me know.
Nice work Jerry. Perfect. That is the short version. Could be
as
much
as 30 inches long..
center of rubber bushing to center of rubber bushing. I am
happy
to
see it fits
the unmodified Mazda oil pan.

Paul, glad you like it. Is there any way using a similar
sheet
metal scheme a single Barry could be placed at the back- center
of
the
engine? It would be part of the welded up engine mount.
Perhaps
it
could be triangulated with the front barrys and lower firewall
bushings. Jerry
I'll have to think about that.

Hey, Jerry.....I have a pan in good condition....it is yours free
if
you
will pay the shipping. Paul Conner
Thanks Paul, yes I will pay the shipping. Easiest way is just to
mail
it to me at:

Hi, again, Jerry.....reading the posts it looks like a few oil pans
are
coming your way....will you still need mine? Paul Conner
Paul, I need two. Yours is one of them. Please send it. thanks
Jerry
Yes Paul he needs it for the Schertz beam static test. Please send.
