Hi Paul,   The throttle bodies are now epoxied in the housings.  This
part of the process went smoothly.  The epoxy, Duralco 4525--- 500
degree,  is extremely slow to cure (8 hrs) and self levels nicely. It
would still flow 3 hours after mixing.  It was nice not to rush.   We
pumped it into the cavities with a syringe.   To back up a couple of
steps.  First, the housings were bored so that the throttle bodies
would have a light interference fit.  Prior to installation, the TBs
were given a light layer of epoxy and then they were driven into the
housing using a dead blow hammer and a piece of wood.  Once that epoxy
cured,  then one side of  the housing  cavity was filled and then after
that cured, the second side was done.  I have taken plenty photos that
I will publish with the final report next week after the insert is
trimmed flush with the rotor housing.  In the meantime here is one.
