Don Bedwell,

       Don did you get the stp file for the rotor housing?
       What do you think?

       Paul Lamar

       Paul,

       I have received many things in the last two days but I don't believe I
   have
       seen this. Who sent it?

       Don

       I
    did. Here it is again.

       Paul Lamar


       Thanks!

       Did you design it? Is it the latest version that Mr. Lin is using?

       Mazda designed the rotor housing. They cost about $400 new from your local
       Mazda dealer.  One of our subscribers did the 3D model. Yes it is the rotor
       housing Charles Lin is using.

       I have others as well.

       Here is just the end housings less the rotor
        housings.
       These are incomplete but useful for components inside cowl 3D's.

       I also have an aluminum version of just the back end housing.

       Paul Lamar



       Paul,

       I am trying to get just what Charles wants me to do. Will you send me any
       and all of the solids that you might have for the EzyCopter airframe and
       existing design with engine plus any other rotary models that you might
       have?

       Don Bedwell

       I have no solids for the
    EzyCopter airframe.
       I am sure Charles has some or perhaps just 2 D drawings.

       I did some aluminum end housing for Charles and he has them.
       His property.

       The main problems are building up a one rotor engine, installing
       the engine in the airframe and test flying it. Do you have an airframe
       or can you build one? If not Jerry Hey can help.

   Hey all,

   Just to note on the rotor housing part file. I have found some errors in
   the surface that will cause huge problems if someone tries to use this
   for machining. The rotor housing surface is not a series of
   discontinuous curves. The dimensions should be 240mm and 180mm if there
   was no offset and 246mm and 186mm with an offset. I don't have a housing
   to measure but I am pretty sure that a Mazda 13b engine uses a offset
   rotor housing surface and a non offset rotor surface. This means the
   dimensions should be
    246mm x186mm. By offset I mean a=3mm.  Maybe that
   is why the tension bolt holes don't look centered in the water channels.
   If this is wrong then the rest needs to be view with skepticism.

   I don't think it was intended to machine rotor housings Rob.
   It was/is cheaper just to buy what Mazda offers.

   Paul Lamar


Just saying to the folks that just because a model is being passed
around does not mean it is gospel that's all. For this model or any for
that matter.

Rob Woods

That is so true. For modeling engine installations however it's external
dimensions are easy enough the check.
