While I have absolutely no relationship with Hayes (I think I spoke with

them

on the phone once), I am going to take the liberty of speaking for them

and

several other small businesses that provide rotary related parts and

service.

I recognize everyone's desire to save money, and the further admirable

desire

of this group to really understand the technical aspects of rotary

aviation

engineering. But please all recognize that small businesses count on

selling

their products and services at a reasonable profit to stay alive. If

Hayes is

offering proven o-rings, and has invested the time, effort, and $$ to
identify the proper configuration, supplier, etc, backed up by

experience in

a large number of rebuilds, then I submit you should BUY the rings from

him

rather than asking him to tell you where you can buy them without paying

him

the small markup that pays for him to learn what works and what doesn't.

While I do advocate a free exchange of information, you should all

recognize

that the small businesses that have developed this information with a

sizable

investment of time and money should be supported by your patronage.

Sincerely,
Jon Lauter
Rotary Power Marine Corporation

Well said Jon. I think it unlikely they will tell you anything Ken.

I am going to order my engine from Hayes, I was just interested in the
diameter of the TES o-rings. The engine I have currently is for my mock up
and core trade in. Both of you are right I never thought of it that way.
