    Would any kind soul have a Cox cylinder head tap (17/32 UNEF) that I could buy or borrow, please? I live in Ireland.

    I have that very tap. I have in the past had people send parts to be tapped. If you want to send the part and pay the freight back I'll get the threads in there for you.

    Thanks JB.

    Steve, thanks for the offer. I'll wait and see what comes out of Guildford first.

    I did find one on the net for $54 but out of stock.

    Dave can you not single point cut the thread or if just cleaning an old one up make a simple tap?

    Will e-mail you too.
