Paul and guys,

Thanks for the quick response.  This info has saved me an afternoon of
work.  Some good news.  I am now back in the saddle with free access to
a complete machine shop again.  Michiwa is now teaching at an industrial
art technical high school and their shop is well equipped but not used
between 15:00 to 19:00. Monday through Friday. I`ve ordered Aluminum
pipe and Teflon sheet, and Aluminum flat bar from Metals Online so I can
make up the P port housings and slide throttles.  I hope to make and
accurate step on the inner housing wall but the shop doesn`t have a
fly-cutter.    Guess I`ll have to make one or borrow one.

Doug.

Hi Doug;

Much easier and more accurate with a boring head arbour (queen's
english).  I think I paid $40-50 years ago.

Cheers

Thanks for the suggestion.  I confused the terms a bit.  Yes it seems we
have this tool at the shop.  I may buy my own as well if I can find out
what type of taper the end mill has..  The shop also has a mill with the
cutting axis in the horizontal position.  This will allow  making
angled-in P-ports as well as the pen type direct in housing injectors
much easier to bore as it is easier to clamp the housing laying flat.
