Subject: ALLOY ROTOR HOUSINGS

 Paul,

 Can you or somebody on line tell me if anybody  does rotor housing exchange
 or if it
 is possible to re machine rotor  housings?
 I need to acquire two 13B housings as mine are unserviceable.  Good ones
 are becoming
 vary rare here in West Australia.

 I hear rumors to that effect  but I don't have any info or experience with
 reman rotor
 housings. My guess  it is not easy to do. I would think it necessary to
 un-plate the
 scared or  pitted chrome and use an NC mill to clean up the steel liners
 and  then
 re-plate the porous chrome  surface.

 Hi Gary

 Are you building an aircraft?

 Here is a source for reground rotor housings.

 You have to copy the link.

 Nothing was said about re chroming. for $125 I can't imagine they could afford to
 re-chrome. With out the porous chrome the life is in doubt.

 BTW porous chrome is an old idea that was used on naval radial aircraft engines in WW
 II. It has also been used on Lyc and Cont flat AC engines.

 Not sure if these guys had been mentioned.  They won't tell you how they
 do it but the price ($99/rotor) , last I heard, probably was worth
 taking the plunge.

 Don't use after market seals with these rotor housing. Steel on steel is a no no.

Hi Gary
I purchased a Renesis test engine some years back.
Some other guys here in Perth did the same.
I take it you've tried Rotomotion here in Perth?

Steve

How's the Glasair coming Steve? Any recent photo's?

Paul Lamar


Hi Steve,
John at Rotomotion is trying to source housings for me but so far not a lot of success.
Still hopeful
Thankyou Paul for your advice and all the info you share via this site.
Cheers
Gary

Your welcome. Perth is one of my favorite places in the world.
Here are some pictures taken at Serpentine airport.
Steve knows most of these people's names.
