Good one... I can sympathize with all of that.

It's all a part of the learning process. Previously we had a Triumph TR6 car. It used the standard 1/4", 3/8", 1/2" and so on nuts/bolts so I was comfortable with that, but I had to get used to calling the hood a bonnet, the trunk a boot, the windshield a windscreen in order to communicate with other LBC owners. My wife was helping me rebuild the front end one day when my son called to see what we were up to. She told him that she was "putting new gaiters on rack"...... all he said was "good grief, now my mom's talking Brit."

It's all a learning process

tnx
George

Now, there's a slant on Classic Vehicle Ownership, George; but at least you were working with familiar fixings. Your (US) NC & NF screws & nuts are, I believe, identically-pitched with our (Brit) UNC & UNF (Unified National Coarse & Fine) imperial threads.

It could've been worse for you. Had you owned a slightly earlier TR, or similar, you'd have been working with totally different BSW threads & spanners (sorry, wrenches!).

The language bit 'ain't no thang' really; entertainment, more than anything. I now even find myself calling my silencers 'mufflers' and my mudguards 'fenders': my mate back in Southampton, where I keep my CB250K, gave me a puzzled look when I told him to expect a delivery, from David Silver Spares, containing a pair of mufflers, and that I'm intending to pull off the fenders & other brightwork for re-chroming locally!

I know you mentioned, in an earlier post here, that "... maybe it's best to just let this thread (doh!) die out for now."; well, my friend, oh no it isn't! The reason I mentioned the hydraulic problems in my previous post is to not only highlight the fact that North America needs to be dragged -- albeit kicking and screaming -- into the scope of the International Standards Organisation (Britain accepted ISO threads and actively started the transition in the mid-sixties, gradually dropping all imperial threads in the ensuing years), but to add some oil to the equation, possibly turning it into another 'oil debate' with some screwie overtones........

My favourite subject! I spent the last 10 years travelling across the Atlantic on engineering projects. Our American cousins are slowly getting the hang of it. The Canadians got the message years ago but it will be a long time before the US adopts International standards.

Did you know that BSP is actually an ISO thread now? Even our close neighbours in the EU struggle with preferred ISO sizes. Those Italians and Germans seem to have their own local metric standards for screw threads when it suits them. My Gilera was covered in whacky sizes.

Only the Brits though, could end up with a mixture of BSF, Whitworth, UNF and Metric on the same vehicle. No wonder they stopped giving away toolkits with cars in the UK.

I've just performed a piece of heresy by putting a 26 tpi 55 degree thread on some CL77 shock bodies I am restoring. My old Myford lathe cuts imperial threads only and I am too mean to buy a metric leadscrew.
