I'm doing a job which requires me to tap a hole in prep for a schrader valve

The thread, according to Schrader's website, is 0.206"-36tpi
This tap is not commonly available from stock.
I know that I can special order this tap, but seems to be an unnecessary
expense for a short run job
If anyone has any of these that they would like to sell, or knows of a
source, please contact me
Maybe a slightly different approach? What if the original part were redesigned
to accept a brazed-in tire valve? You can get a set of 4 all-metal tire valves
from Pep Boys for under $10, or could about 3 years ago anyway. Those of course
have the threads already in them.
Alternatively, you could try making a one-off tap.
