Hand grind a few flutes onto an old pipe plug and use it as a ****ing

What old pipe plug? The local hardware stores only carry blumbing
fittings in plastic, brass, cast iron and some (?) kind of zinc-plated
steel.
I'd have had to order something anyway.... It aint an emergency though.
Don't think the metal in pipe plugs is good enough. You *could* turn
some tool steel between centers and then cut flutes and harden to make
a tap. But, I'd just shop eBay for the real thing.
I thought he had said he was wanting to tap aluminum but looking back I
guess that's not really clear.
