Does anyone here know of a good source I can try to get a Tap & Die
set for the British Fine Pipe Whitworth, etc., etc., fasteners?
I had my tanks dipped and then they sat for quite some time. So
there’s some of the coating and a speck of rust in the threads for
the tank fittings that I’d like to clean out prior to trying to
screen in the brass fittings.–

Sorry to say they don’t seem to be readily available anywhere in UK
at the moment. About the only place I’ve found them are at auto
jumbles where sometimes a stall will have a mixed box of old
equipment and foraging about sometimes throws up a useful size.
Unless of course anyone knows different?–

Snap On is probably an option, although they usually want a kings ransom
for their tools. Try a search for King Dick brand tools, I thought there
was a British tool dealer in the Midwest somewhere, but the name and
place escapes me.

If I recall, the brass threads at the bottom are fairly large
diameter. I think you can use a thread guage from ant tap and die
set and scrape the threads by hand to get the material off. For
that matter, you can make a scraper to do one thread at a time.
The threads form a 60 degree angle.–

They’re in Michigan and do mail order.–

I thought the US SAE fine thread was so close to the UK Fine thread
that they were interchangable. Am I wrong? I know I have replaced
several Jag fine thread bolts with SAE fine thread bolts and have
had no problems thus far. They seem to match up when held together
meshing the threads or runing a nut on them to check for
compatibility.

So far, just FYI, I’ve run into no threads that aren’t matched by what we get
here in the US in a hardware store as coarse, fine, or metric. And, as most
of you may know, I’ve has a personal relationship with most of the fasteners
on both our cars!–

Thanks guys for all the opinions, er ah ‘‘options’’ (yeah, that’s
what I meant). I’ll be trying any and all avenues I can to get the
correct Tap to use for my project.
I find myself agreeing more with Alex on the point that there are
definitely differences in the SAE vs British threads. But I guess
I am yet to be fully educated on the issue. I just know that I
don’t want the fuel to start leaking at the tank fitting because I
used ‘‘something close enough’’ (even though that might be a good
enough fix). It’s that ‘‘purrfectionist’’ in me that wants
it ‘‘stock’’ if possible.
When I get a resolution, I’ll post so we have a record here.
Thanks again!–

Jamie, that’s what plumber’s teflon tape is for!

Can’t comment on what you’ve run into Alex, but there are some
incompatible threads on Jags
The Unified National system used on our era of Jags matches
American and many British threads, although these are definitely
not the same in their original form. There were problems in WW2
with supposed ‘Imperial’ fasteners not being transferable between
British equipment and US equipment. American bolts had flat-
bottomed groves between screw threads, which interfered with
British round-topped nut threads. Likewise, British round topped
bolts wouldn’t fit American nuts properly although many things
can be forced and doubtless were in the heat of battle.
UNF/UNC fasteners were developed with a round-bottom groove to fit
the British threads, and a flat-topped thread to fit the American
threads, so they not only fit with themselves but with either
system. Thank NATO spec for sorting that lot out. We may be ‘two
nations divided by a common language’ but at least we can screw
each other properly…LOL
However, on Jags the BA (mostly electrical) and Whitworth threads
(e.g. in diff casing) are not compatible with US fasteners IMHO, as
the thread angles are 47.5 and 55 degrees respectively. BSP threads
are also incompatible with American fasteners I think. Doesn’t mean
you can’t cobble something together but it’s not the same as the
correct fit. (BSF/BSC/UNF/UNC/SAE and Metric are all 60 degree
thread angle).–

Thanks for the laborious detail Peter, but I’m down to a handful of unvisited
fasteners on both cars and have yet to experience screwing issues.
