hi Paul,

while you are at mazda i would sure like to have a picture of the
trokoid grinding machine.  my oldest son has built two of them and we

are getting ready to reman. the damaged rotor housings, so are curious
as to how the OEM

machinery is made. how are the sides of the housings finished after

the chrome is applied?   wish i could take the tour with you but we are
poor boys ha ha.

thanks a bunch   walt.

Here is an intersting article that explains some of the process. Very
Interesting. It's a bit large at 359KB, but worth it. If Paul does not
publish it, let me know and I will post it on my web site.
