Hello Steve,

I have seen pics of the plates by themselves along with installed ones
in planes with the hoses going different directions. I guess I am
confused as to where the coolant goes after the plug bosses. Does it
come in the middle and then split off fore and aft axially through the
other housings and then back to the center housing and that brazed bung
I see.

Also there has been much mention of your sheet metal housings. There was
discussions of getting some pics up some time ago but I haven't seen
them yet. Do you have those available? Also how much post machining wa
necessary with those housings after brazing? Did the creep at all in the
process? What material were they made out of and what was the brazign
brocess you used in terms of material and heat cycle?

Rob:  coolant flow was as you summarize. Regarding the furnace brazed
housings, as a general summary of the process, we made templates and
drawings for laser cutting and of plates and partitions by BBC Steel.   We
then fixtured housings and shipped for furnace brazing.  When they came back
we  machined and lapped the housings and shipped for nitriding.  After
nitriding, housings were final lapped.  To our surprise distortion in this
process was minimal.  It will be some time before I will be able to go
through the files and extract the photographic prints of the laser cut
pieces jigged and fluxed in various stages.  Meanwhile, I hope this general
information of the steps and process is helpful.
