Have built heads, spark plug does connect with valve cage hole but should not be a problem as it only just breaks into.

will keep McMaster in mind if I need some tools.
Thanks for all your advice, I now have the job done by cutting thread on lathe using a bush to support end while cutting the thread.
Problem I have had with the #3-48 dies is that they are poorly made with excessive burrs on the cutting teeth and incorrectly sized thread size.
I have no issues otherwise with cutting threads in stainless.
i only have eight rods to put #3-48 threads on and may not ever use that thread size again.
have just learnt about something new, re. Coventry Die head, will keep this in mind for other jobs.
Hi,
Where can you buy a quality #3-48 die capable of cutting threads in stainless?
I have tried some Chinese wich were absolute crap, a KS brand made in Japan, it was no good either.
