Lynn and all,

Lynn you are so right on (as usual) about the long drawn out

speculation and guesstimates as to the proper sizes for "TES" seals

for the Rotary........That is why I shipped a side housing to "Creavey"

for proper sizing of both length and cross section..........The Rotary

group always appreciates your knowledge and insight about this

engine that we all are fans of...........

Best Regards
