Ed Anderson and Perry Mick,

         I have contacted Chuck Dunlap about his use of the TES O-rings in his

rotor oil seals..........He got the TES O-rings from Paul L. and the sizes were

what Paul called out at that time.......I am looking for further size and/or

operational info I can get from anyone using the TES O-rings in the rotor

seals........Chuck said that he thought that both of you were currently using

them in your engines........I would appreciate input you can give concerning

their use in your flying engines.........

       I recently shipped a 13B side housing to "Creavey Seal" to settle once

and for all the question of sizes for the coolent TES O-ring seals........ I know

that there is some question in the group as to the need for them particularly

the outer coolent seal as it does not see as much heat as the inner seal.......

      The choice as to the use of these seals is up to the individual........I just

want to make sure that the correct size information is available to all of the

Rotary group.........

     I now have correct size information for the coolent TES O-rings and the

last piece of the puzzle is verification of the rotor oil seal TES O-ring sizes !!

     All info to this point indicates that the oil seal sizes that Paul L. called

out are correct........When all is verified I will stick my neck out and publish

my findings !! FWIW
