   I am building a turbo normalized rotary right now. I want to have it
   totally completed in the next month. I am starting the engine mount
   this
   next week and will be making the oil pan accordingly. How is the actual
   S-Beam made. What material, etc. I appreciate any information you
   could
   send my way. I am convinced the rotary engine is the best
   powerplant for
   aircraft.

   Also, what material and thickness is the oil pan aluminum?

   I have read most of your information concerning your engine mounts. I
   agree that the S-beam is the best way to mount the engine. I will
   attach a picture of the engine I am mimicking regarding the turbo
   install.
   I am only normalizing the engine. I want to start the S-beam today.
   What
   are the dimensions on the bar. It looks like 3? wide or so. I have
   already
   ordered the Barry mounts. They should be here in a
   few days. Thank you very much for your help. I am mounting the
   radiator behind the seat in the fuselage for C.G. reasons. Thank
   both of
   you very much for all of the help!

   Here are the dims Todd.
   What kind of airplane are you building?

   Paul,

   Would you please send me a top screen shop showing all the hole
   dimensions
   for the oil pan? I want to program it into our CNC router and have the
   router punch the holes and cut out the plate. I'm also going to
   have the
   router cut out the sides and bottom of the pan. You don't by chance
   have
   any drawings showing dims for the entire pan do you?

   Also, I am ordering the tubing for the engine mount right now. What
   side
   and wall are the three main struts that triangulate each side of the
   S beam
   to the firewall. It is 5/8 .049 tubing?

   Thank you Paul,

   Todd

   This is all I have right at the moment Todd You will have to wait a
   couple
   of weeks until I get back home.

   Lower side tubes are 1 inch OD .049" wall 4130. Upper side tubes and
   most other
   tubes are 3/4 " OD .049 wall 4130.

   Paul,

   Would you have the same drawings for a 1987 13B,
   Turbo block?

   Jerry has told me that he will not provide the Shertz beam
   unless he has drawings for the oil pan, which he would sell with the
   beam.

   Makes sense as they should be a matched set.

   The application is for a Long-ez

   Thanks,
   Joe Graham


   I don't think we ever bothered to do a dwg of the 1991 turbo engine
   oil pan bolt pattern as people always had them lying around to
   use as a pattern.

   Here are some old obsolete dwgs of the pan without the bolt patterns.
   I would make it larger than this as you will gain some initial
   oil cooling advantages.

   These 3D long EZ dwgs are obsolete as well because of the new
   schertz beam. I'll be home in a couple of weeks and I can do
   some new ones.

If you don't have the old oil pan lying around to use as a template,
take a piece of paper that is large enough and make a rubbing like you
would of a tombstane or plaque. Ensure you don't make a mirror image of
the oil pan. They aren't symetrical are they? I'm too lazy to go out
into the garage and check.
