Paul - I was informed that you could help me get an engine mount designed
and fabricated for my turrentine/renesis 4 port project. the original
owner
built a very nice integral oil pan/bed mount plate which I would like to
use. kevin Lane
Can you send me a picture of it.
Here is my design for an RV7A. The 6A would be similar.
The bell housings is the new Larry Childs version.
This is the asymmetrical version with the water rad on the cool
side. I can also do a symmetrical version with the rad under
the engine.

The shertz beam type arrangement seems to allow the exhaust pipes to
easily
pass thru inside the mount tubing, rather than outside, and provides a
good
mounting points for radiators etc. perhaps my situation would use double
beams, fore and aft. I haven't thought thru the exhaust system yet. on my
prior 20b I had the std. 3 to 1 type (Tracy has it now on his rv-8).
again,
I'll have 3 (4?) exhaust tubes to deal with. one preliminary idea was to
use rad exit air to cool augmented exhaust, altho the space may prove too
tight or curvy. I would be open to the possibility of converting my plane
to a -6, should that make life simpler up front. kevin
That is one of the better oil pan mounts I have seen. The pan is welded to
the plate
which solves the extra oil leak problem. What is the length, depth and
width?
It is a challenge I would like to take and see if I can come up with a
simple
mount. The main problem with these things is 90% of the load is taken by
the two front rubber bushings. I'll work on something now guessing on the
dimensions
for now.
What Jerry Hey does is start with an abbreviated "A" mount that he gets
from
Van's motor mount supplier. He then builds the Schertz beam mount off
that.
Last 2 pictures.

Looks like this will work. That aluminum plate loses 20% of its strength
at 200 F and it is kind of thin around 3/8th inch thick. Should be 1/2
inch.

paul - beautiful illustrations. i have training in Chief Architect, 3D
design software. you need to be using these sophisticated pkgs daily or you
begin to forget many things. i tried the free rhino once, but didn't spend
a lot of time with it. i actually beat my way thru autocad 3D helping mike
mcgee look into an accessory case/dynafocal mount concept. wow, was that
maddening. rhino wasn't as intuitive as i had hoped, like sketch-up (which
i have only just messed with an hour).
an additional plate sandwiched to the existing would be the easiest fix,
or just start over, building a higher capacity pan.
Kevin Lane
Thanks. I use Rhino almost daily and I am still learning tricks after
about 5 years of using it.
A higher capacity pan is a good idea as it takes longer to heat 12 quarts
instead of only six quarts on take off. Take off and climb out is where
most people have trouble with oil overheating.
